Description
By default, when RadGridView is in edit mode, and the user changes the current cell, the new cell enters in edit mode automatically. In some cases, clients may want to change this behavior and end the editing process once the user left the current cell. This behavior is represented in the MS DataGrid control. This article describes how one can achieve the same editing behavior as in MS DataGrid.
Solution
To achieve the desired behavior where cell editing ends upon navigating to another cell, you can customize the GridRowBehavior of RadGridView. This involves creating a custom GridRowBehavior and overriding the OnMouseDownLeft method.
Here is a custom GridDataRowBehavior implementation:
public class CustomGridDataRowBehavior : GridDataRowBehavior
{
protected override bool OnMouseDownLeft(MouseEventArgs e)
{
GridCellElement cellElement = this.GetCellAtPoint(e.Location);
if (cellElement != null)
{
this.GridViewElement.EditorManager.CloseEditor();
}
return base.OnMouseDownLeft(e);
}
}
To apply this custom behavior, register it with your RadGridView. This custom behavior closes the editor when navigating away from a cell. The CellBeginEdit event will trigger for every new cell the user navigates to.
// Example of how to register the custom behavior
gridView.GridBehavior = new CustomGridDataRowBehavior();
