    Syntax
    public class GridDropDownCellModel : GridTextBoxCellModel, ISerializable, IDisposable
    Remarks

    You typically access cell models through the CellModels property of the GridModel class.

    A GridDropDownCellModel can serve as model for several GridDropDownCellRenderer instances if there are several GridControlBase views for a GridModel.

    See GridDropDownCellRenderer for more detailed information about this cell type.

    Constructors

    GridDropDownCellModel(GridModel)

    Initializes a new GridDropDownCellModel object and stores a reference to the GridModel this cell belongs to.

    Declaration
    public GridDropDownCellModel(GridModel grid)
    Parameters
    Type Name Description
    GridModel grid

    The GridModel for this cell model.

    Remarks

    You typically access cell models through the CellModels property of the GridModel class.

    GridDropDownCellModel(SerializationInfo, StreamingContext)

    Initializes a new GridDropDownCellModel from a serialization stream.

    Declaration
    protected GridDropDownCellModel(SerializationInfo info, StreamingContext context)
    Parameters
    Type Name Description
    System.Runtime.Serialization.SerializationInfo info

    An object that holds all the data needed to serialize or de-serialize this instance.

    System.Runtime.Serialization.StreamingContext context

    Describes the source and destination of the serialized stream specified by info.

    Properties

    SupportsChoiceList

    Gets or sets a value indicating whether cells with this cell type should fill the drop-down list with items from the choice list or data source in GridStyleInfo.

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

    If you implement a custom combo box or drop-down list and you do want the item list to be independent from cell settings (and share the same item list among all cells with this cell type) you should set SupportsChoiceList to be False.

    Methods

    CreateRenderer(GridControlBase)

    Throws NotImplemented exception.

    Declaration
    public override GridCellRendererBase CreateRenderer(GridControlBase control)
    Parameters
    Type Name Description
    GridControlBase control

    The grid control.

    Returns
    Type Description
    GridCellRendererBase

    NotImplemented exception.

    Overrides
    GridTextBoxCellModel.CreateRenderer(GridControlBase)

    GetObjectData(SerializationInfo, StreamingContext)

    Implements the ISerializable interface and returns the data needed to serialize the cell model.

    Declaration
    public override void GetObjectData(SerializationInfo info, StreamingContext context)
    Parameters
    Type Name Description
    System.Runtime.Serialization.SerializationInfo info

    A SerializationInfo object containing the information required to serialize the cell model.

    System.Runtime.Serialization.StreamingContext context

    A StreamingContext object containing the source and destination of the serialized stream.

    Overrides
    GridStaticCellModel.GetObjectData(SerializationInfo, StreamingContext)

    OnQueryPrefferedClientSize(Graphics, Int32, Int32, GridStyleInfo, GridQueryBounds)

    Calculates the preferred size of the cell based on its contents without margins and any buttons.

    Declaration
    protected override Size OnQueryPrefferedClientSize(Graphics g, int rowIndex, int colIndex, GridStyleInfo style, GridQueryBounds queryBounds)
    Parameters
    Type Name Description
    System.Drawing.Graphics g

    The System.Drawing.Graphics context of the canvas.

    System.Int32 rowIndex

    The row index.

    System.Int32 colIndex

    The column index.

    GridStyleInfo style

    The GridStyleInfo object that holds cell information.

    GridQueryBounds queryBounds

    graphical bounds

    Returns
    Type Description
    System.Drawing.Size

    The optimal size of the cell.

    Overrides
    GridStaticCellModel.OnQueryPrefferedClientSize(Graphics, Int32, Int32, GridStyleInfo, GridQueryBounds)

    Implements

    System.Runtime.Serialization.ISerializable
    System.IDisposable
