Event Data

The CustomizeTemplate event handler receives an argument of the CustomizeTemplateEventArgs type. The following properties provide information specific to this event.

Property Description
Context Returns the context in which the Template to be customized was created.
Template Provides access to the Template to be customized.


A Pop-up Window Show Action displays a pop-up Window with a specified View. In a Windows Forns application, the PopupForm or LookupForm Template is used, depending on whether a Detail or List View is included. In an ASP.NET Web application, the Dialog.aspx page is used as a Template. To customize the pop-up Window's Template, handle the CustomizeTemplate event that occurs after assigning the Template to the Window. Use the handler's CustomizeTemplateEventArgs.Template parameter to access the Template.

The following code snipped demonstrates a sample CustomizeTemplate event handler implementation. The code displays Actions from the PopupActions category at the top of the pop-up window, in Windows Forms applications.

using DevExpress.ExpressApp.Templates;
using DevExpress.ExpressApp.Win.Templates.ActionContainers;
using DevExpress.XtraLayout;
private void MyPopupAction_CustomizeTemplate(object sender, CustomizeTemplateEventArgs e) {
    foreach (IActionContainer container in e.Template.GetContainers()) {
        if (container.ContainerId == "PopupActions" && container is ButtonsContainer) {
            LayoutControl layoutControl = (LayoutControl)((ButtonsContainer)container).Parent;
            layoutControl.Dock = System.Windows.Forms.DockStyle.Top;
