Hi virender,
What I should do is the following. I should work with a SessionVariable.
Ok, so you have your table.aspx (the popup) and the test.aspx ( the opener).
What should all be set:
-
on the opener, you already assign SessionVariable to the textbox-text. But the SessionVariable hasn't been set yet so the text is just empty. (make sure that with the instantiation of the SessionVariable you assigned it an empty string or whatever, just make sure it's not NULL --> to avoid null reference errors)
-
Now you open the popup, this is where your listitem will be selected.
-
Now you have to store the selected item in your sessionVariable. Something like Session("MyCrossPageVar") = item.text (or whatever)
-
Now just one more thing needs to happen: Close the popup, and refresh the opener
-
When the opener is refreshed, the SessionVariable (which has a new value) is assigned again to the textbox and that's how the value came from the popup to the opener
-
To close the popup and refresh the opener, you should execute some javascript on the popup page. The code has to be something like this:
function closePopupAndReloadOpener() { if (opener && !opener.closed) { opener.location.reload(); } window.close(); }
Please give it a try!
If you have further questions or remarks I'd like to hear them.
Greetz,
Wim

u can use window.opener to access the textbox in the parent window to set the value of textbox before closing the window and if id of textbox is dynamically generated send it in the query string to the popup page
