Hello Markus,

Please copy this code-snippet to your project and let me know whether the problem still occurs.

<script type="text/javascript">

function requestStart(sender, args)

{

alert("Request Start!");

}

</script>

<telerik:RadAjaxManager

ID="RadAjaxManager1"

runat="server"

ClientEvents-OnRequestStart="requestStart">

....

</telerik:RadAjaxManager>

Kind regards,
Daniel

Hi Team,

I am working on Telerik R3 2020.3.915.45 with .NetFramework 4.8.

I am having issue with RadGrid Client Events followed the steps with Migration from RadGrid for ASP.NET To ASP.NET AJAX.

But Still ClientEvents are not getting fired.

<script type="text/javascript">
var _pendingItemDetailWindowActive = false;
var sortColumnHash = [];

function PendingItemDetailWindowOver() { _pendingItemDetailWindowActive = true; }

function PendingItemDetailWindowOut() { PendingItemDetailWindowClose(); }

function PendingItemRowMouseOut(rowIndex) {
this.Rows[rowIndex].Control.style.backgroundColor = "";
}

function PendingItemRowMouseOver(rowIndex) {
if (this.Rows[rowIndex].Control.className.indexOf("disabled") == -1) {
this.Rows[rowIndex].Control.style.backgroundColor = "#DFDFDF";
this.Rows[rowIndex].Control.style.cursor = "hand";
}
}

function PendingItemRowSelecting(row) {
if (row.Control.className.indexOf("disabled") != -1)
return false;
}

function PendingItemRowSelected(row) {
var radWindow = test.Utilities.WindowUtil.openRADWindow("PendingItemEditWindow", "Portlets/ConnectDataQualityManager/PendingItemEdit.aspx?id=" + row.KeyValues["Guid"]);
radWindow.Restore();

var close = document.getElementById("CloseButton" + radWindow.Id);
close.onclick = CloseRadWindow;
}

function CloseRadWindow() {
if (confirm("Clicking OK will close the Detail Window. Warning: Any selections that have been made will be lost. Click Cancel to return to the Detail window.")) {
test.Utilities.WindowUtil.closeRADWindow("PendingItemEditWindow");
}
}

function PendingItemEditWindowCallBack(radWindow, returnValue) {
if (returnValue == "Canceled" || returnValue == "Accepted" || returnValue == "Rejected")
RebindPendingItemRadGrid();
}

function PendingItemEditWindowClose() {
RebindPendingItemRadGrid();
}

function PendingItemDetailWindowOpen(source, key) {
var radWindow = test.Utilities.WindowUtil.openRADWindow("PendingItemDetailWindow", "Portlets/ConnectDataQualityManager/PendingItemDetail.aspx?id=" + escape(key));

var contentFrame = radWindow.GetContentFrame();
contentFrame.onmouseover = PendingItemDetailWindowOver;
contentFrame.onmouseout = PendingItemDetailWindowOut;

var position = FindPendingItemDetailWindowPosition(source);
radWindow.MoveTo(position[0] + 30, position[1] - 300); //+ source.offsetHeight);
radWindow.SetSize(600, 300);

_pendingItemDetailWindowActive = true;
}

function PendingItemDetailWindowClose() {
setTimeout("PendingItemDetailWindowEvalClose()", 1000);
