How to capture Mouse and Key events when the text box cell is in an active edit state in WinForms GridControl?

Platform: WinForms |
Control: GridControl

TextBox cell events

The embedded text box gets the mouse actions when the text box is active. You can subscribe to the embedded textbox's events that are inside a cell by accessing it by using the cell's renderer. Refer to following code examples.


//In Form_Load()
// Creates a text box cell renderer object.
GridTextBoxCellRenderer textBoxCellRenderer = (GridTextBoxCellRenderer)this.gridControl1.CellRenderers["TextBox"];
//Invokes the MouseDown and KeyUp events of the text box
textBoxCellRenderer.TextBox.MouseDown += new MouseEventHandler(textbox_MouseDown);
textBoxCellRenderer.TextBox.KeyUp += new System.Windows.Forms.KeyEventHandler(this.textBox_KeyUp);           
private void textbox_MouseDown(object sender, MouseEventArgs e)
    //Writes the MouseDown action
private void textBox_KeyUp(object sender, System.Windows.Forms.KeyEventArgs e)
    //Writes the KeyUp event



'In Form_Load()
'Creates a text box cell renderer object.
Private textBoxCellRenderer As GridTextBoxCellRenderer = CType(Me.gridControl1.CellRenderers("TextBox"), GridTextBoxCellRenderer)
'Invokes the MouseDown and KeyUp events of the text box
Private textBoxCellRenderer.TextBox.MouseDown += New MouseEventHandler(AddressOf textbox_MouseDown)
Private textBoxCellRenderer.TextBox.KeyUp += New System.Windows.Forms.KeyEventHandler(AddressOf Me.textBox_KeyUp)
Private Sub textbox_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs)
     'Writes the MouseDown action
End Sub
Private Sub textBox_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs)
     'Writes the KeyUp event
End Sub
