DoPostBack from Popup (Child) Window

Hello,

I have a custom control that is used to select a location from a list
of locations. When put on the page it creates an asp:textbox (used to
display the name of the location), a hidden field (which stores the
primary key of the location from the DB) and an image button. When you
click the image button a popup is created that allows you to select an
item from a complex screen (tabbed interface, etc).

The important thing is that when you have selected the location you
wish and click on the "Select" button in the popup it tries to call
_doPostBack on the Parent Window and then close itself. This works
fine as long as you have some form elements on the page the "force"
asp.net to put the __doPostBack function on the page. But, if you
don't have these items then __doPostBack is not created on the page,
and the child window fails by trying to call a parent method that
doesn't exist.

I need a way to force the "parent" page to create the __doPostBack
method whether it thinks it needs it or not.

I looked into GetPostBackClie ntEvent, but I don't think I can use it
since I am in a child window.

Any suggestions?

Thanks.

I am using RegisterClientS criptBlock
and in it I use window.opener.d ocument.forms[0].submit();
this will allow the parent window to post back.

Hello Ather,

Thanks for the quick response. However, in my case I can not just
submit the form as there may be Validators on the "parent" page. I did
find a solution for your future reference.

I perform the following call inside the container page which houses
the child control:

Page.GetPostBac kClientEvent(LC 1, "")

LC1 refers to the child control. This forces asp.net to put the
__doPostBack client javascript onto the page.

Thanks again for your help.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
