Hi,
I am trying to use the declarative client binding method to bind radgrid using webservice. I am having trouble passing the custom argument. When i use the standard 4 arguments everything works. Once i add my custom argument it stops working. i don't get any error, grid doesn't even call the webservice.

Here is what i have in ASPX...

    
            <telerik:RadGrid ID="RadGrid1" AllowSorting="true" AllowPaging="true" AllowFilteringByColumn="true" 
        
                        AutoGenerateColumns="false" runat="server">  
        
                        <MasterTableView > 
        
                            <Columns> 
        
                                <telerik:GridBoundColumn DataField="DocID" HeaderText="DocID" /> 
        
                                <telerik:GridBoundColumn DataField="Title" HeaderText="Title" /> 
        
                            </Columns> 
        
                        </MasterTableView> 
        
                        <PagerStyle Mode="NumericPages" /> 
        
                        <ClientSettings> 
        
                            <DataBinding Location="http://localhost/iProWS/GetGridData.asmx" 
        
                                SelectMethod="GetDataAndCount" EnableCaching="true"  /> 
        
                                <ClientEvents OnDataBinding="RadGrid1_DataBinding" /> 
        
                        </ClientSettings> 
        
                    </telerik:RadGrid>

Here is the java script

    
            function RadGrid1_DataBinding(sender, args)  
        
                    {  
        
                         var methodArguments = args.get_methodArguments();  
        
                         methodArguments.WhereCond = "myValue";  
        
                         args.set_methodArguments(methodArguments);  
        
                   }

i tried to use as listed in the demo, but no luck

    
            function RadGrid1_DataBinding(sender, args)  
        
                    {  
        
                        var myMethodArguments = new Object();  
        
                        myMethodArguments.WhereCond = "myValue";  
        
                        args.set_methodArguments(myMethodArguments);  
        
                   }

Here is the Webservice

    
             <WebMethod(EnableSession:=True)> _  
        
            Public Function GetDataAndCount(ByVal startRowIndex As Integer, ByVal maximumRows As Integer, ByVal sortExpression As List(Of GridSortExpression), ByVal filterExpression As List(Of GridFilterExpression), ByVal WhereCond As String) As Dictionary(Of String, Object)  
        
                    Dim data As New Dictionary(Of String, Object)()  
        
                    data.Add("Data", GetData(startRowIndex, maximumRows, sortExpression, filterExpression, WhereCond))  
        
                    data.Add("Count", DirectCast(Session("Count"), Integer))  
        
                    Return data  
        
                End Function

I greatly appreciate if someone can figure out what i am doing wrong. I looked this post which shows the same as demo but for some reason it's not working for me.

Thanks,
