Popup Control for ASP.NET Web Forms - How to return values from the content page and close the pop-up window on the client or server

This example demonstrates how to add an editor to the popup control's ContentUrl page, get the editor's value, and close a pop-up window on the client or server.

Overview

On the parent page, create a popup control and specify its ContentUrl property. Add an input element to the page and handle its OnClick event to invoke a pop-up window.

<input id="btnShowPopup" type="button" onclick="OnBtnShowPopupClick();" value="Show Popup" />
<dx:ASPxPopupControl ID="popup" runat="server" ClientInstanceName="popup"
    ContentUrl="~/PopupContent.aspx" .../>

On the ContentUrlPage, create a text box editor and two buttons. Create the HidePopupAndShowInfo function that hides the pop-up window and displays the editor's value in an alert message. You can call that function on the client and server.

function HidePopupAndShowInfo(closedBy, returnValue) {
    popup.Hide();
    alert('Closed By: ' + closedBy + '\nReturn Value: ' + returnValue);
}
