public class GridControlBase : ScrollControl, IDisposable, ICancelModeProvider, ISplitterPaneSupport, IScrollBarWrapperContainer, ISupportUpdating, ISupportIntelliMouse, IQueryFocusInside, INonClientPaintingSupport, IThemedControl, ICreateNewWindow, IGridModelSource, IGridWindowlessSite, IGridWindowlessObject, IFindParentForm, IThemeProvider, IVisualStyle
Remarks

GridControlBase implements a view on a GridModel. Several views can be opened for the same model. Changes in GridModel are reflected immediately among all views.

The GridModel provides storage for all data and settings associated with the grid. The GridControlBase implements user interaction and display of the data.

GridControlBase is a user control that is derived from ScrollControl. It lets the user scrolls through grid data with mouse or keyboard. The grid displays a large number of cells where each cell can have its own unique formatting and cell type.

GridControlBase also offers a wide range of events that let you customize the default behavior of the grid at run-time.

Constructors

GridControlBase()

Initializes a new instance of the GridControlBase class.

Declaration
public GridControlBase()

GridControlBase(GridModel)

Initializes a new instance of the GridControlBase class and attaches it to an instance of the GridModel class.

Declaration
public GridControlBase(GridModel model)
Parameters
Type Name Description
GridModel model

The GridModel this control is associated with.

Fields

firstPaint

Declaration
protected bool firstPaint
Field Value
Type Description
System.Boolean

m_bInvertRect

Used internally.

Declaration
protected bool m_bInvertRect
Field Value
Type Description
System.Boolean

recalcScrollBars

Declaration
protected ScrollBars recalcScrollBars
Field Value
Type Description
System.Windows.Forms.ScrollBars

SupportsPrepareViewStyleInfo

By default, the grid will make a copy of any style object before painting and call the PrepareViewStyleInfo event. Changes made to the style object will then be discarded after the painting. Same with DrawCell and other events. Having a copy of the style allows you to change the style object just for drawing purposes. If you do not have any need for this and want to increase scrolling performance of the grid, try setting this property false. But be aware this is only experimental for now ...

Declaration
public bool SupportsPrepareViewStyleInfo
Field Value
Type Description
System.Boolean

Properties

AllowColumnResizeUsingCellBoundaries

Gets or sets a value indicating whether to allow resizing of columns through standard cell boundaries. For GridListControl, it is true by default.

Declaration
public virtual bool AllowColumnResizeUsingCellBoundaries { get; set; }
Property Value
Type Description
System.Boolean

AllowDrawItemRaiseExceptionCatched

Gets or sets a value indicating whether to AllowDrawItemRaiseExceptionCatched. Used internally.

Declaration
public bool AllowDrawItemRaiseExceptionCatched { get; set; }
Property Value
Type Description
System.Boolean

AllowFixFocusWhenCurrentCellIsEditingInMouseUp

Gets or sets a value indicating whether if you press the mouse button inside the grid and release the mouse the grid checks whether the current cell is in editing mode. If that is the case it will make sure that focus is moved to the current cell control. This ensures the grid will properly return focus to the current cell if a message box is shown and closed in a custom event handler.

If this behavior causes problems you should set this property false. One known issue we found is when you open another MDI form within a CellDoubleClick event, in which case the focus would be set back to the original form. If you run into such a situation set this property false.

Declaration
public bool AllowFixFocusWhenCurrentCellIsEditingInMouseUp { get; set; }
Property Value
Type Description
System.Boolean

AllowHScrollOnMouseWheel

Gets or sets a value indicating whether the horizontal scrolling should be enabled on Mouse wheel.

Declaration
public bool AllowHScrollOnMouseWheel { get; set; }
Property Value
Type Description
System.Boolean
Remarks

When it is set to true, it will perform the horizontal scrolling when mouse wheeling occurs with the System.Windows.Forms.Keys.Shift key is pressed. It also allows to scroll horizontally without using the System.Windows.Forms.Keys.Shift key when the vertical scrollbar is disabled.

AllowProportionalColumnSizing

Gets or sets a value to resize the columns proportionally fit its content.

Declaration
public bool AllowProportionalColumnSizing { get; set; }
Property Value
Type Description
System.Boolean

Gets or sets a value indicating whether to allow resizing of rows through standard cell boundaries. No support for GridListControl.

Declaration
public virtual bool AllowRowResizeUsingCellBoundaries { get; set; }
Property Value
Type Description
System.Boolean

AllowTextBoxAutoSize

Gets or sets a value indicating whether to force cell renderers to ignore the GridStyleInfo.AutoSize property and do not automatically resize cells while typing.

Declaration
public bool AllowTextBoxAutoSize { get; set; }
Property Value
Type Description
System.Boolean

AllowViewStyleCacheBaseStyleValues

Gets or sets a value indicating whether the grid can enable caching style property values of GetViewStyleInfo styles when accessed the first time. This will make accessing the same property repeatedly faster (e.g. style.CellValue or style.ReadOnly might be accessed multiple times from different routines for the same style object).

Declaration
public static bool AllowViewStyleCacheBaseStyleValues { get; set; }
Property Value
Type Description
System.Boolean

BackColor

Specifies the background color for the grid.

Declaration
public override Color BackColor { get; set; }

Capture

Gets or sets a value indicating whether System.Windows.Forms.Control.Capture of the parent control with window handle (see GetWindow()).

Declaration
public bool Capture { get; set; }
Property Value
Type Description
System.Boolean

CellRenderers

Gets the collection of GridCellRendererBase objects for the current grid view method.

Declaration
public GridCellRendererCollection CellRenderers { get; }
Property Value
Type Description
GridCellRendererCollection
Remarks

Cell renderers will be created on demand by calling the CreateRenderer(GridControlBase). Each renderer is associated with a GridCellModelBase object that holds its data and has knowledge how to instantiate a renderer and associates it with a grid view.

A renderer is created for each grid view but renderers (of the same cell type) share the same GridCellModelBase instance even though they belong to different grid views.

Examples

The following examples show how to get a reference to the renderer for a specific cell.

            GridStyleInfo style = Model[rowIndex, colIndex];
            GridCellRendererBase renderer = CellRenderers[style.CellType];

CurrentCell

Gets GridCurrentCell object that provides storage for current cell information and manages all current cell operation such as activating, deactivating, saving, editing, and moving the current cell.

Declaration
public virtual GridCurrentCell CurrentCell { get; }
Property Value
Type Description
GridCurrentCell
Remarks

CurrentCell gives you a one stop interface for all current cell related operations. This is useful for an Intellisense-based programming environment since you do not have to dig through many unrelated functions.

Events for the current cell will be raised by the GridControlBase itself. The grid offers many events for the current cell that let you customize the current cell's behavior at any stage of operation.

You can find out about the current cell's position by querying the RowIndex and ColIndex properties of the CurrentCell object in GridControlBase. The HasCurrentCell property tells you if the grid has an active current cell. The HasCurrentCellAt(Int32) method lets you find out if the current cell is at a specific row and column index.

See MoveTo(Int32, Int32, GridSetCurrentCellOptions, Boolean) for a discussion about the order of events that you receive when the current cell is moved.

Examples

The following example shows how you can customize the behavior of the current cell and highlight the whole row of the current cell instead of just the current cell itself.

        /// Current cell will be moving from one position to another.
        protected override void OnCurrentCellMoving(GridCurrentCellMovingEventArgs e)
        {
            e.Options |= GridSetCurrentCellOptions.BeginEndUpdate;
            // Instead of GridSetCurrentCellOptions.BeginEndUpdate we could also
            // sandwich the call in a Begin/EndUpdate pair ourselves ...
            //BeginUpdate(BeginUpdateOptions.InvalidateAndScroll);
        }
        /// Completes a current cell's MoveTo operation indicating success.
        protected override void OnCurrentCellMoved(GridCurrentCellMovedEventArgs e)
        {
            base.OnCurrentCellMoved(e);
            //EndUpdate();
        }
        /// Completes a current cell's MoveTo operation indicating failure.
        protected override void OnCurrentCellMoveFailed(GridCurrentCellMoveFailedEventArgs e)
        {
            base.OnCurrentCellMoveFailed(e);
            //EndUpdate();
        }
        /// Highlight the current row.
        protected override void OnPrepareViewStyleInfo(GridPrepareViewStyleInfoEventArgs e)
        {
            if (e.RowIndex > this.Model.Rows.HeaderCount && e.ColIndex > this.Model.Cols.HeaderCount
                && CurrentCell.HasCurrentCellAt(e.RowIndex))
            {
                e.Style.Interior = new BrushInfo(SystemColors.Highlight);
                e.Style.TextColor = SystemColors.HighlightText;
                e.Style.Font.Bold = true;
            }
            base.OnPrepareViewStyleInfo(e);
        }
        /// Refresh the whole row for the old position of the current cell when it is moved to
        /// a new row or when current cell is deactivated stand-alone.
        protected override void OnCurrentCellDeactivated(GridCurrentCellDeactivatedEventArgs e)
        {
            // Check if Deactivate is called stand-alone or called from MoveTo and row is moving.
            if (!CurrentCell.IsInMoveTo || CurrentCell.MoveToRowIndex != CurrentCell.MoveFromRowIndex)
            {
                RefreshRange(GridRangeInfo.Row(e.RowIndex), GridRangeOptions.MergeAllSpannedCells);
            }
            base.OnCurrentCellDeactivated(e);
        }
        /// Refresh the whole row for the new current cell position when the current cell is moved
        /// to a new row or when current cell is activated stand-alone (and there was no activated current cell).
        protected override void OnCurrentCellActivated(EventArgs e)
        {
            // Check if Activate is called stand-alone or called from MoveTo and row is moving
            base.OnCurrentCellActivated(e);
            if (!CurrentCell.IsInMoveTo || CurrentCell.MoveToRowIndex != CurrentCell.MoveFromRowIndex

Gets or sets a value indicating whether UseGdiPlusRightAlignedTextWorkaround implements a work-around for a GDI+ known issue with right-aligned text and DrawString.

Declaration
public static bool UseGdiPlusRightAlignedTextWorkaround { get; set; }
Property Value
Type Description
System.Boolean
Remarks

When you have cells with right-aligned text some words are not aligned at the right border as you would expect. This is because of GDI+ designed behavior, and the degree of the problem varies from font to font. You can see this behavior for example with regular System.Windows.Forms.Label controls. Since Essential Grid relies on GDI+, it exhibits the same behavior. Besides using a Mono spaced Font, some include using either anti aliased string drawing or explicitly measuring the string width and not relying on DrawString to draw the text right-aligned.

When you enable UseGdiPlusRightAlignedTextWorkaround then the static cell renderer will use the measure string width workaround. However, this will slow down drawing of right-aligned text.

Methods

BeginUpdate(BeginUpdateOptions)

Suspends the painting of the control until the EndUpdate() method is called.

Declaration
public override sealed void BeginUpdate(BeginUpdateOptions options)
Parameters
Type Name Description
BeginUpdateOptions options

Specifies the painting support during the BeginUpdate, EndUpdate batch.
Overrides
Remarks

When many paint are made to the appearance of a control, you should invoke the BeginUpdate method to temporarily freeze the drawing of the control. This results in less distraction to the user, and a performance gain. After all updates have been made, invoke the EndUpdate method to resume drawing of the control.

Pass BeginUpdateOptions if you do not want to do a complete Refresh of the control and instead want to have certain regions of your control be invalidated or scroll the contents of control.

If you call BeginUpdate() and then later EndUpdate(), the control will know if a paint is pending and only refresh the control if a paint is pending. Either call to ShouldPrepareUpdate, Invalidate or a WM_PAINT message during the BeginUpdate EndUpdate block will signal the control that a paint is pending.

GetNextCurrentCellPosition(GridDirectionType, ref Int32, ref Int32)

Determines the next position for the current cell for a given direction. Normally, cells that are not marked as enabled with Enabled will be skipped but you can hook into this mechanism by implementing an event handler for QueryNextCurrentCellPosition.

Declaration
public bool GetNextCurrentCellPosition(GridDirectionType direction, ref int rowIndex, ref int colIndex)
Parameters
Type Name Description
GridDirectionType direction

The GridDirectionType that specifies the direction of the current cell movement.

True if an enabled cell was found; False otherwise.
Remarks

This method will raise the QueryNextCurrentCellPosition event. In your event handler, you can call QueryNextEnabledCell(GridDirectionType, ref Int32, ref Int32) from your QueryNextMoveCell event handler to find out about the next enabled cell and then decide on further criteria if the suggested cell is good.

See the SampleGrid class in the grid pad sample for an example.

UpdateWithCustomPaint(Rectangle, PaintEventHandler)

Allows you to perform a quick Invalidate / Update pair on the grid without executing any of the grids default paint code. Instead you can provide your own routine to update invalidated areas in the grid.

Declaration
public void UpdateWithCustomPaint(Rectangle r, PaintEventHandler customPaintDelegate)
Parameters
Type Name Description
System.Drawing.Rectangle r

The Rectangle
System.Windows.Forms.PaintEventHandler customPaintDelegate

The customPaintDelegate
Examples

The following example lets you draw a small portion of the grid bypassing the grids paint handler (and it trying to recalculating layout cells and other precautions it takes when handling the Paint method).

When compared to calling DrawClippedGrid this approach is a bit slower but it avoids flickering since it can take advantage of the WinForms own double-buffering mechanism.

In OnPaint the grid checks InUpdateWithCustomPaint and if it is true then the grids Paint method will only call the delegate and immediately return.

gridTableControl.UpdateWithCustomPaint(bounds, new PaintEventHandler(TableControl_CustomPaint));
void TableControl_CustomPaint(object sender, PaintEventArgs e)
{
    Rectangle clipBounds = Rectangle.Truncate(e.Graphics.ClipBounds);
    gridTableControl.DrawClippedGrid(e.Graphics, clipBounds, false);
}

UpdateWithDrawClippedGrid(Rectangle)

Allows you to perform a quick Invalidate / Update pair on the grid without executing any of the grids default paint code. Instead the grid will only call DrawClippedGrid from its Paint handler and immediately return.

When compared to calling DrawClippedGrid using a cached graphics context this method is a bit slower but it avoids flickering since it can take advantage of the WinForms own double-buffering mechanism.

Declaration
public void UpdateWithDrawClippedGrid(Rectangle clipBounds)
Parameters
