Is there a way to determine if an <asp:UpdatePanel />
has performed an Ajax postback similar to how we can use...
if(!Page.IsPostBack) { ...snip }
... to determine if a postback from a button submit is taking place.
I'm trying to detect Ajax requests from jQuery, but it's picking up UpdatePanel requests as well which I want to exclude eg...
if (Request.IsAjaxRequest() && !Page.IsUpdatePanelPostback)
{
// Deal with jQuery Ajax
}
I don't know if this will work any better than your solution, but have you tried?:
if (ScriptManager.GetCurrent(Page).IsInAsyncPostBack)
{
Control ctrl = GetControlThatCausedPostBack(Page);
if (ctrl is UpdatePanel)
{
//handle updatepanel postback
}
}
private Control GetControlThatCausedPostBack(Page page)
{
//initialize a control and set it to null
Control ctrl = null;
//get the event target name and find the control
string ctrlName = Page.Request.Params.Get("__EVENTTARGET");
if (!String.IsNullOrEmpty(ctrlName))
ctrl = page.FindControl(ctrlName);
//return the control to the calling method
return ctrl;
}
