PopUp problem
-
Hi! I have a page (say parent page) which has a button(Button1). When the user clicks on 'Button1', a popup screen(child page1) pops up. This child page has a lot of controls. When the user clicks on one of the buttons on this child page , the childpage1 closes and the values entered in child page are displayed on the parentpage controls. I have implemented this using showModalDialog() , __doPostBack() (for the button Button1) and Page.GetPostBackEventReference(Button1 ,string.Empty). The part mentioned above is working absolutely fine. Now, on the same parent page, I have one more button (Button2), which when clicked also opens another pop up page(child page2). In this child page2, I have drop downlist & listbox. The dropdownlist has autopostback (= true) which fills up the listbox. My problem is that, it doesn't fill up the listbox. I have run the debugger within the code-behind , and found that , the items get filled in the listbox but it never shows on the screen. I have implemented this page also with the above mentioned method. I don't understand what the reason is. Can anybody please suggest. Thanks and regards, ap.
