I was doing so ASP.Net 2.0 callbacks (see an overview here: http://dotnet.sys-con.com/read/192509.htm), and kept getting this error when I did a document.location redirect on the ReceiveCallback JavaScript function.
Microsoft JScript runtime error: '__pendingCallbacks[...].async' is null or not an object
Looks like a flagrant Microsoft bug: http://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=101974
People have different suggestions
What worked for me is the setTimeout. However, I needed to pass a parameter to the variable, so I used a technique like so:
var _gRValue;
function ReceiveCallback(rValue)
{
_gRValue = rValue;
window.setTimeout('__ReceiveCallback(_gRValue)',0);
}
function __ReceiveCallback(rValue)
{
//Do stuff here
} //end of method
To handle the nature of setTimeout, I stored the returned data in a member variable.
Thank you! This works great.
Thanks! This works for me, too.
Some EndCallback event handler for ASPxGridView:
function(s, e) {
if (grid1dirty){
grid1dirty= false;
window.setTimeout("grid2.PerformCallback('')",0);
}
