Trigger for Update Panel with Multiple Content Sections on Master Page

Can I use an UpdatePanel in one Content section on a content page with a trigger in another Content section of the same content page?

I have a master page with multiple ContentPlaceHolders which I am using as the template for various pages with a search section and a results section. The search section is contained in one ContentPlaceHolder and the results is contained in another. The content page search section contains an ASP.NET button control (id="btnSubmit") and the content page results section contains an Atlas UpdatePanel containing a Trigger which I would like to tie to btnSubmit. I have tried declaratively to make btnSubmit the trigger, as well as programmatically. When the page loads, I get a "ControlID of trigger must reference valid control" error either way. I have tried substituting btnSubmit.ClientID.ToString inside the trigger definition and this does not work either.

I have another master page/content page combination where both the trigger and the update panel are in the same ContentPlaceHolder/Content section, and I have no problem getting Atlas to work. I am using the April CTP of Atlas.I made a similiar post... I hope I will get a replyhttp://forums.asp.net/1450493/ShowThread.aspx#1450493 from here

Triggering an Updatepanel (b) based on a gridview rowcommand which is inside a UpdatePanel

Hi there,

I have two sections on my aspx page which contain two grids on an aspx page. User and UserDetails.

User section has atab control which contains an update panelupUsers which contains the gridviewgvUsers. I have another grid in a different updatepanelupUserDetails this contains a grid toogvUserAccessKeys. I want to refresh the second updatepanelupUserDetails (basically trigger it) based on the RowCommand in the gvUsers which is in the first update panel. I was able to do this till I added the tab control.

Now it cannot find the gvUsers controlID when I write the trigger.

So is it possible to trigger a different UpdatePanel based on a gridview Control rowcommand event from inside a AjaxControlKit tab control.

Thanks in advance for any suggestions.

Hi,

I have a similar problem, except that I am loading UserControls with GridView dynamically into the TabPanels. The GridView have buttons that should fire RowCommand. The TabContainer is within an UpdatePanel. My RowCommand event is not firing, did you find any solutions to your problem?

Thanks.

Hook the gvUsers RowCreate Event, Find the Button using the FindControl. Once Found, create asyncpostbacktrigger programatically set the control id to the found button id and add the trigger in the second update panel trigger collection.
