Creates a new view or reuses the existing view if reusing can be applied here

Declaration
protected override UISwitch CreateOrRecycleDisplayUIView()
Returns
Type Description
UIKit.UISwitch

Returns a created new view or reuses the existing view if reusing can be applied here
Overrides
Syncfusion.SfDataGrid.GridVirtualizingCellRendererBase<UIKit.UISwitch, UIKit.UISwitch>.CreateOrRecycleDisplayUIView()

OnCreateDisplayUIView()

Creates a new UIKit.UISwitch view.

Declaration
protected override UISwitch OnCreateDisplayUIView()
Returns
Type Description
UIKit.UISwitch

A new UIKit.UISwitch view.
Overrides

OnInitializeDisplayView(DataColumnBase, UISwitch)

Initializes the column element of a Syncfusion.SfDataGrid.DataColumn object with the given UIKit.UISwitch and required values.

Declaration
public override void OnInitializeDisplayView(DataColumnBase dataColumn, UISwitch view)
Parameters
Type Name Description
Syncfusion.SfDataGrid.DataColumnBase dataColumn

The dataColumn containing the details of the column.
UIKit.UISwitch view

A UIKit.UISwitch view to be hosted inside the column element.
Overrides

OnUnloadViews(DataColumnBase)

Called from UnloadViews(DataColumnBase) after a cell is scrolled out of view. GridVirtualizingCellRendererBase<T1, T2> overrides this method and either removes the cell renderer visuals from the parent canvas or hide them and reuse it later in same canvas depending on whether AllowRecycle was set.

OnUpdateCellValue(DataColumnBase)

Updates the toggle value of the UIKit.UISwitch.

Declaration
protected override void OnUpdateCellValue(DataColumnBase dataColumn)
Parameters
