Hi there,
programming with Visual Studio 2005 and ASP.NET 2.0 I want to open a modal
dialog from Default.aspx.
I searched the net and many newsgroups but I couldn't find any solution.
First I tried using two aspx pages with standard controls and all those
post-backs and their attributes OnClientClick. Since this didn't work, i
reduced it to a default.aspx page opening a pure html-page as a modal
dialog.
On the second form I am using a input control of type "submit" and a little
client side script "Sub Submit1_onclick " which sets the return value and
calls "window.close() ". But instead of closing the modal dialog and
returning to the caller window, it opens a new internet explorer instance
showing the same controls as the modal dialog window. Very annoying!
All I can do to close the modal dialog is clicking the white cross on the
red background in the right corner of the dialog's window. This will close
the dialog and return to the caller's window but has several drawbacks: the
return value gets lost and the user cannot choose between Ok and Cancel.
Here's my code:
======== Default.aspx =============== =============== =======
