I want to open a window on a button click (favorite is ImageButton) and do some searches there.
The search should be in a grid view and give the information back directly into a textbox.
How is this possible? (best would be without javascript directly)
Client-side Option:
Server-side Option:
Postback your window that is open, save the data somewhere so that is retrievable by the other page, emit javascript:
window.opener.submit();self.close();on it’s postback to cause your other page to then postback and the open window to close. Have your code-behind retrieve the data needed and change your TextBox.
