ShowViewStrategyBase.ShowViewInPopupWindow Method

Show the specified View in a popup dialog with OK and Cancel buttons.

Namespace:DevExpress.ExpressApp
Assembly:DevExpress.ExpressApp.v17.2.dll

Expanded Syntax

Parameters

view
Type: View
A View to be shown in a popup.
okDelegate
Type: Action
A System.Action delegate to be executed when the OK button is clicked. This parameter is optional.
cancelDelegate
Type: Action
A System.Action delegate to be executed when the Cancel button is clicked. This parameter is optional.
okButtonCaption
Type: String
A string specifying the custom caption of the OK button. This parameter is optional.
cancelButtonCaption
Type: String
A string specifying the custom caption of the Cancel button. This parameter is optional.

Expanded Remarks

The ShowViewInPopupWindow method displays the dialog containing the specified View and two buttons - OK and Cancel. Both these buttons close the dialog. Additionally, if the okDelegate and cancelDelegate handlers are specified, they are executed when the corresponding button is clicked. The following code displays the Contact List View in a popup:

Here, Application is the XafApplication object. For instance, it can be accessed using the Controller.Application, ActionBase.Application or Frame.Application property.

Expanded Web Application Specifics

The ShowViewInPopupWindow method provides a platform-agnostic way to display popup dialogs from your code. However, there are certain specifics in ASP.NET applications:

  • The ShowViewInPopupWindow method can be used on XafCallbackManager callbacks initiated by the RaiseXafCallback script. It cannot be used on callbacks of controls (e.g., grid sorting).
  • It is impossible to pause the current request to wait for the user input.
  • Main window is not refreshed when the Cancel button is clicked.
