Reply To: Numeric Combobox Editor with AllowFreeText=True

For the KeyPress event, you need to subscribe to it when the editor actually becomes active, and for the QueryInputKey and QueryInputChar, you need to subscribe to the ones that are on the CellEditorManager.

e.g. :

Dim t_CboNumber As New Xceed.Grid.Editors.ComboBoxEditor
t_CboNumber.TemplateControl.Items.Add(1)
t_CboNumber.TemplateControl.Items.Add(5)
t_CboNumber.TemplateControl.Items.Add(10)
t_CboNumber.TemplateControl.Items.Add(15)
t_CboNumber.TemplateControl.Items.Add(20)
t_CboNumber.TemplateControl.AllowFreeText = True

GridControl1.Columns( 3 ).CellEditorManager = t_CboNumber

AddHandler GridControl1.DataRowTemplate.Cells( 3 ).KeyPress, AddressOf CellKeypress

AddHandler GridControl1.Columns( 3 ).CellEditorManager.QueryInputKey, AddressOf Col3_CellEditorManager_QueryInputKey

AddHandler GridControl1.Columns( 3 ).CellEditorManager.ActivatingControl, AddressOf Col3_CellEditorManager_ActivatingControl

AddHandler GridControl1.Columns( 3 ).CellEditorManager.DeactivatingControl, AddressOf Col3_CellEditorManager_DeactivatingControl

//HANDLERS

Private Sub CellKeypress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs)
If IsNumeric( e.KeyChar ) then
e.Handled = False
Else
e.Handled = True
End If
End Sub

Private Sub Col3_CellEditorManager_QueryInputKey( ByVal sender As Object, ByVal e As Xceed.Grid.Editors.QueryEditorInputKeyEventArgs )
Dim editor as WinComboBox = CType( e.Control, WinComboBox)
System.Diagnostics.Debug.WriteLine( “in QueryInputKey” )
End Sub

Private Sub Col3_CellEditorManager_ActivatingControl( ByVal sender As Object, ByVal e As Xceed.Grid.Editors.CellEditorEventArgs )
Dim editor as WinComboBox = CType( e.Control, WinComboBox)
AddHandler editor.TextBoxArea.KeyPress, AddressOf editor_KeyPress
End Sub

Private Sub Col3_CellEditorManager_DeactivatingControl( ByVal sender As Object, ByVal e As Xceed.Grid.Editors.CellEditorEventArgs )
Dim editor as WinComboBox = CType( e.Control, WinComboBox)
‘this needs to be done, if not, subscriptions will pill up every time the editor is activated
RemoveHandler editor.TextBoxArea.KeyPress, AddressOf editor_KeyPress
End Sub

Private Sub editor_KeyPress( ByVal sender As Object, ByVal e As KeyPressEventArgs )
System.Diagnostics.Debug.WriteLine( “in KeyPress of editor” )
End Sub
