I have read all the posts I could find which covers this often discussed topic, but have not been able to find anything which covers my scenario, so please bear with me.

A) I have a button which shows the popup via server in code behind (I cannot use client code to do this in this case)   I would like to use an updatepanel to only draw the modalpopup.

B) I also have buttons inside the popup which case postbacks.  I would like to have the popup stay open when the buttons are pushed.

 

I know how to accomplish each of the above independently.

A) Enclose the popup in an updatepanel, and define the button as a trigger.   Works.

B) Inside the popup, enclose the buttons which cause postbacks.  Works.  The popup stays open.

But when A and B are done together, A works, but B does not.  When buttons are pushed, the popup disappears.

Is it because an updatepanel is nested in another one?  I cannot think of a solution. 
 

Please post the exact html markup.

Hi Profnachos,

It is recommended to use this kind of page layout.

<UpdatePanel UpdateMode="Conditional">

<Panel tied to ModalPopupExtender> <UpdatePanel UpdateMode="Conditional">Buttons here.<UpdatePanel> </Panel>

 <ModalPopupExtender></ModalPopupExtender>

<Buttons which triggers UpdatePanel and show the ModalPopupExtender>

</UpdatePanel> 

Best regards,

Jonathan

hi,

the solution provided by Jonathan should work.

just want to add there is no need to put second updatepanel  <UpdatePanel UpdateMode="Conditional">Buttons here.<UpdatePanel>

as first updatepanel is enough.

Still if it doesnt solve ur problem...u can write modal ModalPopupExtenderID1.Show() [modalpopup id of the panel that u want to show] as the last line of submit button.

Thanks
