Update Trigger and GridView problem

Hi!

I have an Accordion on my page. In one AccordionPane, i have an UpdatePanel containing a GridView and a button under. When i try to access my gridview in the code-behind, i encounter a problem. The trigger of my button doesn't work, the method associated with my button isn't called. If i click a second time and the button, it postback my page and i lose all the data and the page. if i click a third time, the trigger associated with the button finally works.

I only get this problem when i try to access my GridView in my page.

I add my code and underlined the line which causes the problem, i remove it everythin works fine

*/

}

if (HiddenModify_NavigationMode.Value =="2")

{

int l_intMonitoringMandateId =Convert.ToInt32(HiddenModify_MonitoringMandateId.Value);

monitorings.GetMonitoringMandateByMonitoringMandateId(l_intMonitoringMandateId);

gainOptions.GetMandateOptionsByMonitoringMandateId(l_intMonitoringMandateId);

HiddenModify_GainMandateOptionId.Value =Convert.ToString(gainOptions.GetMandateOptionFromIndex(0).MandateOptionId);

GridView gridViewGainOption_StartSecurities = (GridView)AccordionPaneGainOption.FindControl("GridViewGainOption_StartSecurities");

The problem comes if I add the line above

//sellDetails.GetMandateOptionDetailsByMandateOptionId(Convert.ToInt32(HiddenModify_GainMandateOptionId.Value));

//gridViewGainOption_StartSecurities.DataSource = sellDetails.TABLE;

//gridViewGainOption_StartSecurities.DataBind();

AccordionPaneSignaletique_DataBind();

AccordionPaneGainOption_DataBind();

}

}

}

Does anyone know what i can do? Can i add the trigger of the updatePanel in the code behind in the pageload method ?

Thanks in advance,

I've been looking for this problem for all my weekend and i found what was the problem!!!!!!!

The problem comes from the Accordion component, during the Page_Load, the Accordion and the child component doesn't exists, but in my case i didn't get any error of "not found controls".

I found a fix on this page :

Thanks a lot to this guy!

i just added Accordion.FindControl("nothing") on a Page_Init and it works great now!
