GridView RowDataBound event makes my GridView slow

Question

I have a PopupExtender that shows some information when a button in the GridView is pressed. This button exists on every row.

I also have a DropDownList present in every row that is populated by querying a database. I do this because it may be populated with different items depending on the row.

The problem I have is that the PopupExtender is slow to pop-up because of the RowDataBound event of the GridView that repopulates the DDLs from the database when the PopupExtender's associated button is pressed.

How can I make the PopUpExtender pop-up faster?

You may need to consider jQuery Dialog instead of Asp.Net ajax popup extender. http://jqueryui.com/dialog/.

Also, do you really need gridview, You can try ListView control instead of GridView.

I'm looking into jquery dialog now. I will test the ListView but why would it be faster ? – UrsulRosu Jun 20 '13 at 07:18
AJAX Popup extender use postback to open/close the dialog window... jQuery UI will be handling this in client side. – Deepu Madhusoodanan Jun 20 '13 at 07:21
I require postback to get the information that is shown inside the AJAX Popup. It may be different for each row. – UrsulRosu Jun 20 '13 at 07:25
That is fine, you can use jquery ajax to do a postback and get the content based on the id or what ever parameters and render in jquery ui dialog window. for ex: Open some thing like this. – Deepu Madhusoodanan Jun 20 '13 at 07:28
On postback will the GridView be rerendered ? Because that is where is the slowness -> Database query for the DDLs in the grid. Generally the grid won't have many items but for 10 items there is a big delay – UrsulRosu Jun 20 '13 at 07:33
if you use jQuery ajax post, it wont rendered gridview again, it will hit only a specific custom method. – Deepu Madhusoodanan Jun 20 '13 at 07:40
Thanks! I'm trying to implement this now! – UrsulRosu Jun 20 '13 at 07:42
