Yea, I figured out how to call the control and set its value grand. The problem that I am getting is: "Object reference not set to an instance of an object".
Let me explain what I am trying to do, I aquired the Janus Web Grid for .NEt from Janusys. This grid allow you to group data according to a specific field. What I was trying to do is insert a checkbox on the top of each group, which would then allow me to select all the checkboxes in that group (that working - used javascript from Janusys). Now I am trying uncheck the checkbox for a particular group if after checking it, i uncheck one of the checkboxes under the group.
Any suggestions.
