Right Click to select Row

[User (Old forums)]

#14294 |

I have the following code for selecting a row by right clicking. The first time I right click on a row, it will take a few seconds before the row is selected. After that, right clicking on any row will select the row instantly. Any ideas why???

In Form Load:
GridControl5.BeginInit()
Dim row4 As Xceed.Grid.DataRow
For Each row4 In GridControl5.DataRows
Dim cell As Cell
For Each cell In row4.Cells
AddHandler cell.MouseDown, AddressOf Data_MouseDown
Next cell
Next row4
GridControl5.EndInit()

Private Sub Data_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs)
If e.Button = MouseButtons.Right Then
Dim row As Xceed.Grid.Row = Nothing
row = CType(sender, Xceed.Grid.DataCell).ParentRow
If Not (row Is Nothing) Then
If row.CanBeCurrent Then
GridControl5.CurrentRow = row
GridControl5.CurrentRow.BringIntoView()
GridControl5.SelectedRows.Clear()
GridControl5.CurrentRow.IsSelected = True
End If ‘Assing grid.ContextMenu based on CurrentRow (other code)
End If
End If
End Sub

Thanks

I don’t know why it takes so long, could be adding all those handlers. A better implementation might be:

Don’t do anything in the form load and add a mouse down event handler to the whole grid
<PRE>
Private Sub GridControl5_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs)
If e.Button = MouseButtons.Right Then
Dim clickedCell As Xceed.Grid.Cell = DirectCast(GridControl5.GetVisualGridElementAtPoint(e.Location), Xceed.Grid.DataCell)
If Not (clickedCell Is Nothing) Then
Dim clickedRow = clickedCell.ParentRow
If Not (clickedRow Is Nothing) And clickedRow.CanBeCurrent Then
GridControl5.CurrentRow = clickedRow
GridControl5.CurrentRow.BringIntoView()
GridControl5.SelectedRows.Clear()
GridControl5.CurrentRow.IsSelected = True
End If ‘Assing grid.ContextMenu based on CurrentRow (other code)
End If
End If
End Sub
</PRE>

I think that’s right, my Vb.NET code maybe a little sloppy but you get the idea.
