RadGrid bug: this._dataSource[...] is null or not an object"

To populate a grid, I call an asmx web service and get back the following JSON string from the JavaScript deserializer:

[{"CustomerId":"ALFKI","ContactName":"Maria Anders","ContactTitle":"Sales Representative","Address":"Obere Str. 57","City":"Berlin","Region":"","PostalCode":"12209","Country":"Germany","Phone":"030-0074321","Fax":"030-0076545"}]

This is grid which is consuming the data:

<telerik:RadGrid ID="GridCustomers"

runat="server"

AllowFilteringByColumn="true"

GridLines="None"

AllowPaging="true"

AllowSorting="true">

<DataBinding Location="http://localhost/Niit/CustomerServices.asmx"

EnableCaching="true"

SortParameterType="Linq"

SelectMethod="GetCustomers"

SelectCountMethod="GetCount">

</DataBinding>

</ClientSettings>

<telerik:GridBoundColumn SortExpression="CustomerId" DataField="CustomerId" HeaderText="Customer ID" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

At run time, I get an exception in the Telerik JavaScript file when this line of code is executed:

var x=this._dataSource[y][t]; // this line appears before "function U()"

This is the value of this._dataSource in the watch window:

this._dataSource = "[{"CustomerId":"ALFKI","ContactName":"Maria Anders","ContactTitle":"Sales Representative","Address":"Obere Str. 57","City":"Berlin","Region":"","PostalCode":"12209","Country":"Germany","Phone":"030-0074321","Fax":"030-0076545"}";

Any ideas as to why I'm getting this exception?

Thanks in advance.

User Control access controls in the hosting Page with master page

Hi All,

I am working on a case which is copying the example

Grid / Editing with external form

In which the grid is in a user control (ascx) and the external form is in the hosting page(aspx). However my .aspx is using masterpage.

I got reference error when try to access controls in the hosting page from the .ascx like:

this.Page.FindControl("pnlExternalForm").Visible = true;//code in .ascx

pnlExternalForm is in the hosting .aspx page

The codes works fine if I put them into a case without masterpage.

I think the code is right, but just not work

Any idea?

TIA

Jerry

Setting the controlparameter of a ListBox which points to same RadGrid where the Listbox is used

I'm having trouble with the controlparameter of a ListBox which points to same RadGrid where the Listbox is used.

I want to populate the Listbox depending on the selected value of the Grid, so I've set a controlparameter in the datasource of the ListBox which points to the selectedItem of the Grid. However, the controlparameter always gets the default value. If I set the controlparameter to another grid (not the grid which is the parent of the ListBox) it works fine.

    
            <GRID id=g1 Datasource = DS1>  
        
                <VIEW> 
        
                <EDIT> 
        
                    <LISTBOX Datasource=DS2></LISTBOX> 
        
                  </EDIT> 
        
            </GRID> 
        
            <DS1> 
        
                ...  
        
            </DS1> 
        
            <DS2> 
        
                <selectparameters> 
        
                    <asp:ControlParameter ControlID="g1" DefaultValue="0" Name="id" PropertyName="SelectedValue" Type="Int32" />   
        
                </selectparameters> 
        
            </ds2>

                        OnClientContextMenuItemClicking="BeforeClientContextHandler" Height="60%"></telerik:RadTreeView>         
                        <TABLE cellSpacing="2" cellPadding="0" width="260">         
                        <TR>         
                          <TD onclick="AddControlsPostBack(<%= AllControlsTree.ClientID %>);" >Cell xxx

                        </TABLE>
