Show confirmation dialog from the code behind ASP.NET
I want to show confirmation dialog from code.
I have a comfirm A dialog, when I click OK on A, this is a call to method B in the hind code (using ajax post: url / B and B - the method has a webmethod attribute).
In method B I want to show another dialog and the code is flowing: (B - AlertInformLogOut)
[WebMethod]
public static void AlertInformLogOut(string alertId, string option)
{
//TODO: Open call schedule
var page = HttpContext.Current.Handler as Page;
// PopUp alert notify info
if (page != null)
{
page.ClientScript.RegisterStartupScript(page.GetType(), "script", "AlertSetDialog(" + new JavaScriptSerializer().Serialize(new AlertInformEntity()) + ", 'AlertInforms');", true);
//ScriptManager.RegisterClientScriptBlock(page, page.GetType(), "script", "AlertSetDialog(" + new JavaScriptSerializer().Serialize(new AlertInformEntity()) + ", 'AlertInforms');", true);
}
}
problem: The dialog is not displayed.
Can anyone tell me why and I can show a dialog from a method with a webmethod attribute.

The problem is, as I recall, the WebMethod does not update the page, unlike the ASP: update panel callback.
Since you are using the jQueries ajax function , use a callback instead of trying to do it on the server side.
$.ajax({
type: "POST",
url: url+"/UpdateAlertInfo",....,
success: /*Call you Confirm Function Here */
}
You may want to consider using $. post () instead of
