Hello Sir,

I need to fire an event back to server so that I can know which GridItem selected by user. I used the script code as:

function OnItemSelected(grid)
{
var item = grid.getSelectedItem();
var value = item.getCell(2).getValue();
var info;

if (chkCell.getValue() == 0)
{
info = "Selected Item Index: " + item.getIndex() + value;
}
else
{
info = "Selected Item Index: " + item.getIndex() + value;
}
var div = document.getElementById("divCurrentInfo");
div.innerHTML = info;
eo_TriggerServerEvent("gridMaster",
"any_value, this argument is not used",
info);

The Server side code is as following:
protected void gridMaster_Command(object sender, CommandEventArgs e)
{
string msg;

msg = e.CommandArgument.ToString();
}

After I run it, it has en error on client side as: Object doesn't support this property or method.
Then I go into the debug mode of client script, it is display the error is in the :

Object doesn't support this property or method eo_web.ashx?id=41fa4079-c07d-4021-b0da-a37f2945922d, line 6 character 23424

Please help to give me an workable example to trigger an event from client side to server side. Thank you very much.
