If we have a client template on a column, is there an easy way to have the multi filter use that value?

 

columns.Bound(c => c.Logon).Filterable(f => f.Multi(true)).ClientTemplate("#= FullName #")

 

We want FullName in the filter dropdown.

Hello Marc,

The Grid does not provide this functionality out of the box.

A possible solution for achieving the desired behavior is handling the filterMenuInit event. In the event handler function, get the list of node values and update the text using the same logic as the client template.
For example, the code might look like:

filterMenuInit: function(e){
  e.container.children().first().children().each(function(e){
    var label = $(this).find("label");
    var text = label[0].lastChild.nodeValue;
     
    label[0].lastChild.nodeValue = changeLabelText(text);
  });
},
 
 
//...
 
function changeLabelText(text){
  if(text==="Select All") return text;
 
  return text + " +templateText";
}

For a runnable example, check this Dojo: http://dojo.telerik.com/exubA

I hope the above helps.
