How to rerturn value from showmodaldialog

Using the following javascript code you can return a variant value from modaldialog window to parent window.
When you call showModalDialog you do this:
Code:
var oReturnValue = window.showModalDialog("subDoc.html",argsVariable, "dialogWidth:300px; dialogHeight:200px; center:yes");
Within showModalDialog, assuming your textboxes have IDs of "txtForename" and "txtSurname":
Code:
function terminate()
{
var o = new Object();
o.forename = document.getElementById("txtForename").value;
o.surname = document.getElementById("txtSurname").value;
window.returnValue = o;
}

Then continuing in your main window:
Code:

alert(oReturnValue.forename + "\n" + oReturnValue.surname);

Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "AjaxControlToolkit.Properties.Resources.NET4.re

Error Message:


Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "AjaxControlToolkit.Properties.Resources.NET4.resources" was correctly embedded or linked into assembly "AjaxControlToolkit" at compile time, or that all the satellite assemblies required are loadable and fully signed

Resaon :


AjaxControlToolkit’s control load reference refers to the base System.Web.UI.Control method which is present as a part of the ASP.NET AJAX Libraries and those libraries are referenced only when the ScriptManager is referenced in the page.

Solution:


Add ScriptManager in the page and this error would be resolved.

<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
