Manager to display progress in an ASP. NET AJAX application. The Page. Request. Manager class handles the partial page updates of the Update. Panel. This class defines client events that you can use during an asynchronous request cycle. Let us see how to use some events of this class to display progress to the user while the Update. Panel updates its contents. Drag and drop a Buttonbtn. Invoke and Labellbl. Text control inside the Update. Panel. Also add a lt dividdiv. Image inside the Update. Panel. This div will contain a. On the button click, perform a time consuming task. In our case, we have set a delay of 3 seconds by using Thread. Sleep3. 00. 0.  C    protectedvoid btn. InvokeClickobject sender, Event.

Manager and then wire up the initialize. Request and end. Request events to execute, when an async postback begins and ends respectively. When the user initiates a postback by clicking on the button kept inside the Update. Panel, we set a delay of 3 seconds. To display progress to the user, we handle the Initialize. Request at the client side and set the div. Image to visible. This shows up the. The button that caused the postback is disabled during this event, so in order to prevent users from hitting the button again. Note Remember that you cannot have simultaneous async postbacks using ASP. NET AJAX. When the async postback completes in our case when 3 seconds are over, the end. Request event gets fired. The div. Image is set to invisible, there by hiding the gif image and the button is enabled again. Method 2 Using the Update. Progress control to display progress in an ASP. NET AJAX application. Another very simple option to display progress during an async postback is to use the Update. Progress control. You can use this control to display status information to the user, while the Update. Panel updates its content. In the example below, we use the same. Update. Panel is updating its content. For understanding purposes, we have emulated a time consuming operation by setting a delay of 3 seconds by using Thread. Sleep3. 00. 0 on the button click. C    protectedvoid btn.
