DropDownList Value not changing with UpdatePanel and ModalPopupExtender
- by Richard
Greetings,
I have an asp.net webpage with an modalpopupextender inside of an updatepanel. When I click Ok on the popup, I can get the textbox values from the popup just fine, but the DropDownLists have the old/default value, not the new value I have selected for them.
All the controls on the popup are set to enableviewstate = true, and autopostback = false (I just want to make the trip to the server when I click the ok button, not every time I change the value of the popups).
Here is the relevant code.
