Introduction

The UpdateProgress control enables you to provide feedback about the progress of partial-page rendering. For postbacks or initial page rendering, UpdateProgress control content is not displayed.

The page can contain multiple UpdateProgress controls. Each one can be associated with a different UpdatePanel control. Alternatively, you can use one UpdateProgress control and associate it with all the UpdatePanel controls on the page.

The UpdateProgress control renders a div element that is displayed or hidden depending on where a postback originates and whether the AssociatedUpdatePanelID property of the UpdateProgress control is set.

Associating an UpdateProgress with an UpdatePanel Control

You associate UpdateProgress controls with an UpdatePanel control by setting the AssociatedUpdatePanelID property of the UpdateProgress control. When a postback event originates from inside an UpdatePanel control, any associated UpdateProgress controls are displayed. If you do not set the AssociatedUpdatePanelID property, the UpdateProgress control displays progress for any asynchronous postback that originates from inside any UpdatePanel control. It is also displayed for any controls that are triggers for panels.

The AssociatedUpdatePanelID property has the following effect on UpdateProgress control behavior:

When the AssociatedUpdatePanelID property is not set, the UpdateProgress control is displayed for the following postbacks:
- Postbacks that originate from inside any UpdatePanel control.
- Postbacks that originate from controls that are asynchronous triggers for any UpdatePanel control.
When the AssociatedUpdatePanelID property is set to an UpdatePanel control ID, the UpdateProgress control is displayed for postbacks that originate from inside the associated UpdatePanel control.

If the AssociatedUpdatePanelID property is set to a control that does not exist, the UpdateProgress control will never be shown.

If the ChildrenAsTriggers property of the UpdatePanel controls is set to false and a postback originates from inside an UpdatePanel control, any associated UpdateProgress controls will still be displayed.

Specifying the Content of the UpdateProgress Control

Use the ProgressTemplate property to specify the message that is displayed by an UpdateProgress control. If the ProgressTemplate property is empty, nothing is shown when the UpdateProgress control is displayed.

The template can contain HTML and markup. For example, you can display an animated image that notifies the user that the postback is processing. You can also display a button that the user can click to stop the partial-page update. Additionally, you might want to prevent all other postbacks while one is in progress. The following example shows client script that you can use to accomplish these tasks.

</html>

You can use the example code by setting the onClick attribute of an HtmlButton control to "AbortPostBack()".

Putting UpdateProgress Controls on the Page

UpdateProgress controls can be inside or outside other UpdatePanel controls. The display of the UpdateProgress control's template does not depend on where the UpdateProgress control is located. In a nested UpdatePanel control, a child panel is inside a parent panel. In that case, a postback that originates from inside the child panel causes all UpdateProgress controls associated with the child panel and the parent panel to be displayed. If a postback originates from an immediate child control of the parent panel, only the UpdateProgress controls that are associated with the parent panel are displayed.

Customizing When UpdateProgress Controls Are Displayed

By default, the UpdateProgress control waits 0.5 seconds (500 milliseconds) before it displays its contents. This helps prevent the control from flashing if an asynchronous postback is very quick. You can specify the delay by setting the DisplayAfter property.

If you need finer control over when an UpdateProgress control is displayed, you can provide client script for the beginRequest and endRequest events of the PageRequestManager class. In the beginRequest event handler, you can display the DOM element that represents the UpdateProgress control. In the endRequest event handler, you can hide it.

You must provide client script to display an UpdateProgress control when a target UpdatePanel control is updated in the following circumstances:

When a postback from a control is registered as an asynchronous postback trigger for the panel, and there is an UpdateProgress control on the page. However, the AssociatedUpdatePanelID property is not set to the panel's ID.
When postbacks from controls are registered as asynchronous postback controls by using the RegisterAsyncPostBackControl method of the ScriptManager control.

Applying CSS Styles

The UpdateProgress control accepts expando attributes. This makes it possible to set a CSS class on the HTML elements that the controls render. For example, you might create the markup shown in the following example:

<asp:UpdateProgress runat="server" class="myStyle">  
</asp: UpdateProgress>

The markup in the previous example renders HTML similar to the following when the page runs:

<div id="ctl00_MainContent_UpdateProgress1" class="myStyle">  
</div>
