I hava a button to pop up a child window, on the event on close on that pop up window,  i will assign a value to a textbox on the parent window. After assign, i will close the child window.

But I got problem, if the textbox on parent window is visible, i can assign the value, BUT if the textbox is not visible, I cant assign and close the child window, and I need that textbox to be invisible, please advice me.

"window.opener.Form1." & _
HttpContext.Current.Request.QueryString("ctrlNameHidden") & ".value = '" & _
strDTM & "';window.close();"

Thanks You.

Hi,

I dont think assigning values to hidden text box is possible.

Why dont you use hidden controls instead? I am sure it will work.

Do let me know in either case.

Cheers!

Please mark as answer if it helps!

You can use an asp:textbox control don't set it to visible="false" on the server.  Rather add a style attribute to set it's visibility to hidden.

e.g. 

       ctrlNameHidden.Attributes.Add("style", "display:none;")

put this in the page load event 

Your could also use something like this

<input type="hidden" id="ctrlNameHidden" runat="server">

Hope this helps
