In general, you should only have Update Panels areound areas where you wish to do partial updates.Don't wrap your entire page within an Update Panel, and don't be afraid to use several panels, since this will give you more control of which areas update and when they do it.aspdotnet-suresh offers C#articles and tutorials,csharp dot net,articles and tutorials, VB. Now you can ask questions directly to me on my new site ASPForums. While registering we need to provide the Control name along with the data item for the control which we want to render. we can call args.get_data Items()to retreive the data from the dataitem collections.If we click on Button1 now, it will update the text of Label1, but though we have registered the Label2 with the script manager still its value will not be reflect. After that we have set the Control Value by from the data item collection using .
The Content Template tag is required, since it holds the content of the panel.
The Update Panel control is probably the most important control in the ASP. It will AJAX'ify controls contained within it, allowing partial rendering of the area.
We already used it in the Hello world example, and in this chapter, we will go in depth with more aspects of the control.
This thing is quite simple when we are trying to update any control which is inside the updatepanel itself. We have one Button say Button1, which is also inside the Update Panel.
But, The problem may come when we want to update the controls which are outside of Update Panel and we need to update the same while updating then control inside updatepanel. Now, our requirement is to update the Label2 while we are updating Label1 by Clicking Button1.
