Customizing Editor

Updated over 6 months ago

The appearance and behavior of property grid editors can be changed programmatically. This can be done in the EditorInitialized event. EditorInitialized is fired when the editor is created and initialized with a predefined set of properties.

The following sample demonstrates how to change the default font of a BaseTextBoxEditor in RadGanttView:

C#

private void GanttViewElement_EditorInitialized(object sender, GanttViewItemEditorInitializedEventArgs e)
{
    BaseTextBoxEditor editor = e.Editor as BaseTextBoxEditor;
    if (editor != null)
    {
        ((RadTextBoxElement)editor.EditorElement).Font = new Font(FontFamily.Families[12], 12, FontStyle.Bold);
    }
}

VB.NET

Private Sub GanttViewElement_EditorInitialized(sender As Object, e As GanttViewItemEditorInitializedEventArgs)
    Dim editor As BaseTextBoxEditor = TryCast(e.Editor, BaseTextBoxEditor)
    If editor IsNot Nothing Then
        DirectCast(editor.EditorElement, RadTextBoxElement).Font = New Font(FontFamily.Families(12), 12, FontStyle.Bold)
    End If
End Sub

Mask Editor

The following sample demonstrates how to change the default font of a GanttViewDateTimeEditor in RadGanttView and apply MaskDateTimeProvider with a custom format for time:

C#

private void GanttViewElement_MaskEditorInitialized(object sender, GanttViewItemEditorInitializedEventArgs e)
{
    GanttViewDateTimeEditor dtEditor = e.Editor as GanttViewDateTimeEditor;
    if (dtEditor != null)
    {
        dtEditor.CustomFormat = "hh/mm/ss";
        MaskDateTimeProvider dtprovider = ((BaseDateTimeEditorElement)dtEditor.EditorElement).TextBoxElement.Provider as MaskDateTimeProvider;
        dtprovider.AutoSelectNextPart = true;
    }
}

VB.NET

Private Sub GanttViewElement_MaskEditorInitialized(ByVal sender As Object, ByVal e As GanttViewItemEditorInitializedEventArgs)
    Dim dtEditor As GanttViewDateTimeEditor = TryCast(e.Editor, GanttViewDateTimeEditor)

    If dtEditor IsNot Nothing Then
        dtEditor.CustomFormat = "hh/mm/ss"
        Dim dtprovider As MaskDateTimeProvider = TryCast((CType(dtEditor.EditorElement, BaseDateTimeEditorElement)).TextBoxElement.Provider, MaskDateTimeProvider)
        dtprovider.AutoSelectNextPart = True
    End If
End Sub
