How to get the selected text from a TextBox cell?

2 mins read

In order to get the selected text from a TextBox cell in WinForms Grid Control, the TextBox renderer has to be acquired from the CurrentCell renderer inside the CurrentCellStartEditing event.

Code Snippet


// form()
// Trigger the required event.
gridControl1.CurrentCellStartEditing += gridControl1_CurrentCellStartEditing;
void gridControl1_CurrentCellStartEditing(object sender, CancelEventArgs e)
    GridCurrentCell cc = this.gridControl1.CurrentCell;
    if (cc.Renderer is GridTextBoxCellRenderer)
       GridTextBoxCellRenderer renderer = cc.Renderer as GridTextBoxCellRenderer;
       renderer.TextBox.MouseUp += TextBox_MouseUp;
void TextBox_MouseUp(object sender, MouseEventArgs e)
    TextBox text = sender as TextBox;
    if (text.SelectionLength > 0)



' form()
' Trigger the required event.
Private gridControl1.CurrentCellStartEditing += AddressOf gridControl1_CurrentCellStartEditing
Private Sub gridControl1_CurrentCellStartEditing(ByVal sender As Object, ByVal e As CancelEventArgs)
 Dim cc As GridCurrentCell = Me.gridControl1.CurrentCell
 If TypeOf cc.Renderer Is GridTextBoxCellRenderer Then
    Dim renderer As GridTextBoxCellRenderer = TryCast(cc.Renderer, GridTextBoxCellRenderer)
    AddHandler renderer.TextBox.MouseUp, AddressOf TextBox_MouseUp
 End If
End Sub
Private Sub TextBox_MouseUp(ByVal sender As Object, ByVal e As MouseEventArgs)
 Dim text As TextBox = TryCast(sender, TextBox)
 If text.SelectionLength > 0 Then
 End If
End Sub
