UPDATE: I was able to get the value of column, but I have another question:
I have the following, how do I open up a link to a new window without getting the "sys.webforms.pagerequestmanagerparsererrorexception: the message received from the server could not be parted" error? I'm trying to assign a http link.
protected void gridAdmiral_ItemCommand(object source, GridCommandEventArgs e)
if (e.CommandName == "Open")
string id = ((GridDataItem)e.Item).GetDataKeyValue("ID").ToString();
string url = GetOpenLink(id);
"window.open('" + url + "','_blank')");
