using c#.net/asp.net 2005.
I have a collapsiblepanelextender that is working well when the user clicks on the "expand" and "collapse" buttons on the screen, however I would like to programmatically expand and collapse the collapsiblepanelextender in the c# code-behind. Has anyone done this before?
I am typing the name of the collapsiblepanelextender in the code behind function and intellisense is not even showing that control as being a control that I can access from the aspx page so not certain why this is happening.
when I look in the aspx page the collapsiblepanelextender has a red squiqqly error line under it that says (when you mouse over it): "element 'collapsiblepanelextender' is not a known element. this can occur if there is a compilation error in the website"
but the panel works well when the user clicks it to expand and collapse and there are no compilation errors on the page, otherwise the page would not run, does this make sense?
