Accessing the Editors and Changing their Properties.

Since the editors are created each time when the user starts edit operation, they can by accessed in the CellEditorInitialized event. The following example shows how you can access some of the editors and change their properties.

void radVirtualGrid1_CellEditorInitialized(object sender, VirtualGridCellEditorInitializedEventArgs e)
    var dateTimeEditor = e.ActiveEditor as VirtualGridDateTimeEditor;
    if (dateTimeEditor != null)
        var editorElement = dateTimeEditor.EditorElement as RadDateTimeEditorElement;
        editorElement.Format = DateTimePickerFormat.Custom;
        editorElement.CustomFormat = "dd/MM/yyyy";

    var dropDownListEditor = e.ActiveEditor as VirtualGridDropDownListEditor;
    if (dropDownListEditor != null)
        RadDropDownListEditorElement element = dropDownListEditor.EditorElement as RadDropDownListEditorElement;
        element.DisplayMember = "Name";
        element.ValueMember = "Name";

        element.DataSource = GetTable();

    var textBoxEditor = e.ActiveEditor as VirtualGridTextBoxEditor;
    if (textBoxEditor != null)
        var editorElement = textBoxEditor.EditorElement as RadTextBoxEditorElement;
        editorElement.TextBoxItem.ForeColor = Color.Red;

Private Sub radVirtualGrid1_CellEditorInitialized(ByVal sender As Object, ByVal e As VirtualGridCellEditorInitializedEventArgs)
    Dim dateTimeEditor = TryCast(e.ActiveEditor, VirtualGridDateTimeEditor)
    If dateTimeEditor IsNot Nothing Then
        Dim editorElement = TryCast(dateTimeEditor.EditorElement, RadDateTimeEditorElement)
        editorElement.Format = DateTimePickerFormat.Custom
        editorElement.CustomFormat = "dd/MM/yyyy"
    End If
    Dim dropDownListEditor = TryCast(e.ActiveEditor, VirtualGridDropDownListEditor)
    If dropDownListEditor IsNot Nothing Then
        Dim element As RadDropDownListEditorElement = TryCast(dropDownListEditor.EditorElement, RadDropDownListEditorElement)
        element.DisplayMember = "Name"
        element.ValueMember = "Name"
        element.DataSource = GetTable()
    End If
    Dim textBoxEditor = TryCast(e.ActiveEditor, VirtualGridTextBoxEditor)
    If textBoxEditor IsNot Nothing Then
        Dim editorElement = TryCast(textBoxEditor.EditorElement, RadTextBoxEditorElement)
        editorElement.TextBoxItem.ForeColor = Color.Red
    End If
End Sub
