in the OnClientItemClicked event the clickedMenuItem is null and the hidden form field which is set in the RowContextMenu is null? Am i using the right event?

in RowContextMenu "hiddenClientID" is correctly set to the ClientID key field

// process content menu

function RowContextMenu(sender, eventArgs) {

var colIndex = eventArgs.get_domEvent().target.cellIndex;

var rowIndex = eventArgs.get_itemIndexHierarchical();

var masterTable = sender.get_masterTableView();

cell = masterTable.getCellByColumnUniqueName(masterTable.get_dataItems()[rowIndex], "ClientID");

var ClientID = cell.innerHTML; //

document.getElementById("hiddenClientID").value = ClientID;

var radGridClickedRowIndex = document.getElementById("hiddenClientID").value;

var menu = $find("<%=RadContextMenu1.ClientID %>");

var evt = eventArgs.get_domEvent();

if (evt.target.tagName == "INPUT" || evt.target.tagName == "A") {

return;

}

var index = eventArgs.get_itemIndexHierarchical();

sender.get_masterTableView().selectItem(sender.get_masterTableView().get_dataItems()[index].get_element(), true);

menu.show(evt);

evt.cancelBubble = true;

evt.returnValue = false;

if (evt.stopPropagation) {

evt.stopPropagation();

evt.preventDefault();

}

function contextMenuItemClicked(sender, args) {

var clickedMenuItem = args.get_item().get_value();

var radGridClickedRowIndex = document.getElementById("hiddenClientID").value;

var grid = $find('<%= RadGrid1.ClientID %>');

var masterTableView = grid.MasterTableView;

var row = masterTableView.get_dataItems()[radGridClickedRowIndex];

var cell = masterTableView.getCellByColumnUniqueName(row, "ClientID");

if (clickedMenuItem == "Edit") {

editClient();

}

if (clickedMenuItem == "Calendar") {

AddAppoint(cell.innerHTML);

}


<telerik:RadContextMenu ID="RadContextMenu1" runat="server" OnClientItemClicked="contextMenuItemClicked"             EnableRoundedCorners="true" EnableShadows="true" Skin="Metro">

duh, operator error. I did not sent a value="" in the context menu

also, since the hidden form field had the ClientID Key, all I needed to do was this:

function contextMenuItemClicked(sender, args) {

var clickedMenuItem = args.get_item().get_value();

var radGridClickedRowIndex = document.getElementById("hiddenClientID").value;

if (clickedMenuItem == "Edit") {

editClient(radGridClickedRowIndex);

}

if (clickedMenuItem == "Calendar") {

AddAppoint(radGridClickedRowIndex);

}
