Constructors

DataGridCheckBoxSelectorCellRenderer()

Initializes a new instance of the DataGridCheckBoxSelectorCellRenderer class.

Declaration
public DataGridCheckBoxSelectorCellRenderer()

Methods

OnCreateDisplayUIView()

Creates the display view (checkbox) for a data row or header.

Declaration
protected override StackLayout OnCreateDisplayUIView()
Returns
Type
Microsoft.Maui.Controls.StackLayout
Overrides
Syncfusion.Maui.DataGrid.DataGridCellRenderer<Microsoft.Maui.Controls.StackLayout, Microsoft.Maui.Controls.View>.OnCreateDisplayUIView()

OnCreateEditUIView()

Creates the edit view (same as display view since checkbox is not editable).

Declaration
protected override View OnCreateEditUIView()
Returns
Type
Microsoft.Maui.Controls.View
Overrides
Syncfusion.Maui.DataGrid.DataGridCellRenderer<Microsoft.Maui.Controls.StackLayout, Microsoft.Maui.Controls.View>.OnCreateEditUIView()

OnInitializeDisplayView(DataColumnBase, StackLayout)

Initializes the display view (called when rendering a data row cell). This renderer only handles data rows. Headers are handled by DataGridCheckBoxSelectorHeaderCellRenderer. Selection synchronization is now handled via RaiseSelectionChangedEvent interception in the DataGrid class.

Declaration
protected override void OnInitializeDisplayView(DataColumnBase dataColumn, StackLayout view)
Parameters
Type Name Description
Syncfusion.Maui.DataGrid.DataColumnBase dataColumn
Microsoft.Maui.Controls.StackLayout view
Overrides
Syncfusion.Maui.DataGrid.DataGridCellRenderer<Microsoft.Maui.Controls.StackLayout, Microsoft.Maui.Controls.View>.OnInitializeDisplayView(Syncfusion.Maui.DataGrid.DataColumnBase, Microsoft.Maui.Controls.StackLayout)

OnUnloadViews(DataColumnBase)

Unloads the views and unsubscribes from events to prevent memory leaks and stale event handlers.

Declaration
protected override void OnUnloadViews(DataColumnBase dataColumn)
Parameters
Type Name Description
Syncfusion.Maui.DataGrid.DataColumnBase dataColumn
Overrides
Syncfusion.Maui.DataGrid.DataGridCellRenderer<Microsoft.Maui.Controls.StackLayout, Microsoft.Maui.Controls.View>.OnUnloadViews(Syncfusion.Maui.DataGrid.DataColumnBase)

OnUpdateCellValue(DataColumnBase)

Updates the cell value when the underlying data changes. This is called by the DataGrid when refreshing cells.

Declaration
protected override void OnUpdateCellValue(DataColumnBase dataColumn)
Parameters
Type Name Description
Syncfusion.Maui.DataGrid.DataColumnBase dataColumn
Overrides
Syncfusion.Maui.DataGrid.DataGridCellRenderer<Microsoft.Maui.Controls.StackLayout, Microsoft.Maui.Controls.View>.OnUpdateCellValue(Syncfusion.Maui.DataGrid.DataColumnBase)
