How to trigger the SelectionChanged event by Keypress in WinForms GridControl?
1 min read
SelectionChanged event
The SelectionChanged event gets raised when we move the CurrentCell to another cell by mouseclick. But it doesn't get raised when we move the CurrentCell by keypress.
Solution
To trigger selectionchanged event when key pressed you can either use ListBoxSelectionMode as one or enable selection in CurrentCellMoving event.
C#
//Method 1
this.grid.ListBoxSelectionMode = SelectionMode.One;
//Method2
this.grid.CurrentCellMoving += new GridCurrentCellMovingEventHandler(grid_CurrentCellMoving);
this.grid.SelectionChanged += new GridSelectionChangedEventHandler(grid_SelectionChanged);
void grid_CurrentCellMoving(object sender, GridCurrentCellMovingEventArgs e)
{
this.grid.Selections.Add(GridRangeInfo.Row(e.RowIndex));
}
void grid_SelectionChanged(object sender, GridSelectionChangedEventArgs e)
{
if (e.Reason == GridSelectionReason.SelectRange)
{
MessageBox.Show("SelectionChanged Event fired");
GridRangeInfo range = e.Range;
}
}
VB
'Method 1
Me.grid.ListBoxSelectionMode = SelectionMode.One
'Method2
AddHandler grid.CurrentCellMoving, AddressOf grid_CurrentCellMoving
Me.grid.SelectionChanged += New GridSelectionChangedEventHandler(grid_SelectionChanged)
Private Sub grid_CurrentCellMoving(ByVal sender As Object, ByVal e As GridCurrentCellMovingEventArgs)
Me.grid.Selections.Add(GridRangeInfo.Row(e.RowIndex))
End Sub
Private Sub grid_SelectionChanged(sender As Object, e As GridSelectionChangedEventArgs)
If e.Reason = GridSelectionReason.SelectRange Then
MessageBox.Show("SelectionChanged Event fired")
Dim range As GridRangeInfo = e.Range
End If
End Sub
