I am trying to retrieve the filter client-side to pass to a dialog window being displayed.  I am calling the get_filterExpression() method on the MasterTableView but an empty string is being returned.  Is this a bug or does it require something special.

function GetFilterData() {  
 
    var filterString = "";  
      
    var filter = $find(GridMasterView).get_filterExpressions();  
    for (var i = 0; i < filter.length; i++)  
        filterString += filter[i].get_columnUniqueName() + "~" + expression.get_fieldValue() + "~";  
          
    return filterString;  
          

Please let me know how I can accomplish this.

Thanks

Stephen

Hello Graham,

Here's a forum link which discusses on how to get your filter expression on client. This should probably help you out.

So effectively what you are saying is that the function to get the filter expression client-side doesn't work.  This solution is basically a hack to bypass the client-side function.  However, how does this work in an ajax situation where only the grid is updated?

Hello Stephen,

RadGrid's client-side filtering and sorting expressions are maintained only for client-side binding. They are not mirrored from and to the server-side properties. Therefore, the post that Princy referred to, demonstrates the only way you can access server-side properties on the client, i.e. by saving them to hidden inputs.
