Modal Popup moving data from popup to parent

Posted By:      Posted Date: September 02, 2010    Points: 0   Category :ASP.Net
I have one page with a panel that makes up my ModalPopup. On the ModalPopup there is an updatepanel with a textbox and a button in it.There is a textbox on the "parent" page and I want to click the button on the modalpopup and move the data from the popup textbox to the parent textbox. So far, no joy. I have a line in the code behind to move the data between textboxes and I have also tried javascript to do the same thing but I am not able to make this happen unless i click the button twice.Any help is appreciated.

Modal Loading Popup on Async Postback

Hi everyone, I have a web application that does some complicated data retrieval tasks and so I am trying to show a modal dialog box with a loading message when the tasks begins. I am using ASP.Net 3.5, the jQeury popup I am using is bPopup. Firstly, I have a table where the rows can be clicked. Im am using a script from http://bloggingabout.net/blogs/mveken/archive/2008/01/02/performing-async-postback-from-javascript.aspx to do an async postback from the table row. Here is my functionfunction Server(eventName, eventArgs) { $("#<%=lDiv.ClientID %>").openPopup(); var prm = Sys.WebForms.PageRequestManager.getInstance(); if (!Array.contains(prm._asyncPostBackControlIDs, eventName)) { prm._asyncPostBackControlIDs.push(eventName); } if (!Array.contains(prm._asyncPostBackControlClientIDs, eventName)) { prm._asyncPostBackControlClientIDs.push(eventName); } __doPostBack(eventName, eventArgs); } so the $("#<%=lDiv.ClientID %>").openPopup();  opens up my loading modal and then the server starts doing its thing. When the server finishes though how would I then close the dialog box? I just need to call one line of code like $("#<%=lDiv.ClientID %>").closePopup(); Thanks for your help
