I'm wondering why I can't find the updatepanel control in my codebehind file Page_Load event. I have several gridviews, each in their own accordion control/pane, all inside an updatepanel (which I was planning to split into one for each accordion when I finally get one UpdatePanel working). I guess it is probably something of which I am ignorant. -
upFull = (UpdatePanel) this.Page.FindControl("upFull");
-
// the previous line returns null so please be gentle with the beatdown :)
-
gvMyWG = (GridView)upFull.ContentTemplateContainer.FindControl("gvMyWG");
-
-
gvMyGG = (GridView)upFull.ContentTemplateContainer.FindControl("gvMyGG");
-
//Next thing I do is call a static method and pass all grids by reference to set all gridview datasources to a SqlDataReader that is getting multiple result sets (MARS).

Are your update panels in the MasterPage?
Or are your update panels in a regular ASP page or Web User Control?
If so, you shouldn't have to use the FindControl to locate your GridViews.
Frinavale,
Thanks for your response. I am sorry I wasted your time. Evidently I did write this properly the first time around, but I kept getting a compiler error when passing GridViews via reference. "Object not set to an instance" so I figured I was doing something wrong (because they were within the UpdatePanel). That's when I started with the "please god let this work because I am falling behind" code :). This isn't the first time that I have written the code properly but the IDE chokes when and gives me build errors. It seems like it is caching it somewhere and refuses to update it when I do a clean solution/rebuild.
Once again thanks for your help.
Evidently, I stepped on my "jump to conclusions mat" and celebrated too soon. After I deleted my class variables which were part of the "please god" code, I am now getting the original error message again. "The name gvMyGridView does not exist in this context".
Here is the control hierarchy:
MasterPage
ContentPage
ContentPlaceHol der
UpdatePanel
Accordion
GridView
In the page_load event I am just trying to pass each gridview by reference to a static method so they can be bound to a Sqldatareader. I guess I will try ripping out the UpdatePanel for now.

I have a page with a LoginView which contains a Gridview and a

I'm having a bit of a proooblem.
I have a gridview which has a checkbox as one of the templatecolumn's. When it is checked, it hides a textbox containing a DateTime templatefield (visible="false" which I set in the RowDataBound Event).

Hi,
I am new to implementing Asynchronous javascript in asp.net (or any framework) and have come across a problem.
In a user control I have an accordion with a nested updatepanel, the trigger is a link button in the header. I have read several posts that suggest I need to add the ControlID in the codebehind, so I have and I don't get any errors, but also there's nothing loading into the updatepanel.
Here's the code;

Hi All,
I am implementing a custom gridview control, that emits some javascript to blink a row whenever a new row is added in gridview. The gridview is inside the <asp:updatepanel> for parital page rendering. The problem is when I put the gridview inside the updatepanel, I don't see the HTML table that is created as a result from rendering the gridviewcontrol and thus when new row is added, it does not blink, however when i just put the...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
