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

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!
