Hello Jennifer,

LINQ is one of the example that we can use. Fortunately, I use LINQ. We can use any other way to bind data in ClientBinding. For another sample, I have attached another simple sample using dataset. In this sample, I am not validate the data yet, so WebCombo just retreive all data from dataset. 

As far as I know, WebCombo MultipleSelection feature is created just like multipleSelection in MS outlook. So it can't handle MultipleSelection with drop down, but if you want, you can create a feature request for this feature.

Hope this helps.

Hi Roger,

It is impossible to change the header columns in prepareDataBinding Event like that. WebGrid could read the code but cannot render it.
To change header column, I suggest you to set the inner text in column only on client side. You can remove your WebGrid PrepareDataBinding Event, and then change the client side code with this following code:

 function ViewByType(type, thisControl) 
       {
            var grid = ISGetObject("grid");

            document.all["hid_type"].value = type;

            thisControl.className = "HoverLinkSelected";

            if (type == '0') 
            {
               document.getElementById("type_criterion").className = "HoverLinkNormalFontSize";
               // add this code to changes header column
               grid.RootTable.Columns.GetNamedItem("CategoryID").GetElement(WG40.COLHEADER, WG                40.HTMLDIV).parentNode.childNodes[1].innerText = "ISBN Code";
            }
            else {
                document.getElementById("type_book").className = "HoverLinkNormalFontSize";    
                // add this code to changes header column
                grid.RootTable.Columns.GetNamedItem("CategoryID").GetElement(WG40.COLHEADER, WG                40.HTMLDIV).parentNode.childNodes[1].innerText = "Book Code";            }
            //remove this method
            //grid.Refresh();
        }	

Hope this helps.
