Using a Repeater inside of UpdatePanel with UpdateProgress

Question

User879393986 posted

Hello there, I am using ASP .NET 4.0 using C#.  I have a web form where all of my layout exists within an UpdatePanel.  Inside it I have the following:

Panel for entering search criteria with textboxes and search button

UpdateProgress with animated .gif

Panel with a Repeater that gets populated according to my first sproc (using the search criteria) - inside each row is a LinkButton that when clicked calls my second sproc and populates a Panel within the Repeater row.  I am populating the Panel in the code-behind in the ItemCommand event of the Repeater.  I use the CommandArgument on the LinkButton for my second sproc.  I have a CollapsiblePanelExtender to animate the Panel that contains data from my second sproc.

I have it working but not the way I want.  When the search button is clicked the UpdateProgress does show my animated .gif.  However, when the LinkButton is clicked within the Repeater datarow my second sproc takes about 6 seconds to process.  I want to have an UpdateProgress that shows an animated .gif when this occurs.  I tried to fix this by implementing a second UpdatePanel but I could not get the UpdateProgress to fire at all.  Any help would be greatly appreciated.  Thanks in advance.

I have this all working now.

After much digging I found this: http://stackoverflow.com/questions/8716362/how-to-do-asyncpostbacktrigger-for-the-linkbutton-in-the-repeater

I was able to use this in my Page directive: ClientIDMode="AutoID"

I also ended up adding an ImageButton to my Repeater datarow, and whether I click on the LinkButton, ImageButton, or Search button I get the desired result now - the UpdateProgress fires and displays the animated .gif file.

My UpdateProgress resides inside of my UpdatePanel and has an AssociatedUpdatePanelID set to the ID of my UpdatePanel.

I hope this helps someone.

Hi xanalyth,

Why you try to use the ClientIDMode as "AutoID" model?

Doing so allowed my UpdatePanel to see the LinkButton control within the Repeater.  Without it I would get an error stating that the control was not found.  I did try the code in the first answer in that link that I posted and it worked okay.  However, the second answer states that using the AutoID is a better match for what I was trying to do - so I went with that solution instead.

Thanks.
