I have a gridview inside UpdatePanel.
Inside gridview there is a dropdownlist and a button on each row. On button click I am opening a panel through Modal popup extneder.
Inside that pop up there is again a dropdownlist. I am adding an item into this dropdownlist based on the selection from the dropdown inside gridview.
But first time this inserted item is not getting reflected in the dropdownlist. But after one postback this item is getting reflected.
Please let me know how to fix this. I tried UpdateMode conditional and always but didn't worked. If I am not clear let me know.
I've created a dynamic button from another control outside of the update Panel. The button is given an ID and such. When the button is click, a postback occurs and I've re-created this button during Page_Init, Page_PreLoad, and Page_Onload and NONE of them is preserving the value.
The only way for me to find the control was to look at the Page.request.form's allkeys and compare the string with a any text string that contains: Button. Because I ID'd teh button as: ButtonRow_0Col0. But the actual ID is null. However, when traversing through page.request.form, the allkeys shows that ID with no problem.
So how come the actual ID is lost after a partial postback yet, the page.request.form's allkeys can pull out its allkey's value??
I have been writing C# code for about 3 years now and have never had this happen.
I am using an asp:repeater (inside an update panel):
<asp:Repeater runat="server" ID="rptRedFolderDocs" OnItemDataBound="rptDataBound">
inside the repeater I have a button with a click event with server side code.
When the page loads, the repeater is databound to a datatable popuplated from SQL connection. The repeater is NOT bound on postback. I wanted the data to persist.
When the button is click
Iuse UpdatePanel for my pages, clients requested to view pages without flickering.
So, I put all component in update panel, but after that, export and printing for Crystal Reports stoped to work. If I put report viewer outside of updatepanel its working.
Have anyone this problem? There's some solution for this?

I am displaying large amount of data in gridview,the gridview placed within updatepanel,every 1sec i am refreshing updatepanel using ajax timer.my problem is while displaying large data the cpu performance is low,pls give idea to increase cpu performance..
I have one Panel on ascx control to which I have attached one Modal popup extender. On this panel I have one RadioButtonList control which having SelectedIndexChanged on which I have made CheckBoxLists visible True/False.
I want to add Update panel to this Panel . So when I handled the SelectedIndexChanged event there should be no total page post back, only Panel updates should be happen.
Please do reply..
I'm having a somewhat odd issue, I'll do my best to explain it.
The UpdateProgress loading notification appears on the first postback but not on the second, even though both of them function correctly. The buttons that trigger both postbacks are async postback triggers in the update panel, and both are inside the ContentTemplate.
It's not a huge problem, but it causes some confusion, has anybody ever seen this issue before?
