Hi,

I'm trying to get a grid to load its data from the client side after the parent control has been initialised.

I'm trying to use the set_datasource method to populate the grid with data from a JSON serialised DataTable from a webservice.

I want the grid to create its columns automatically from the datatable if possible.
However, when I call get_masterTableView(), null is returned.

Is what I'm trying to do possible, and if so where am I going wrong?

Thanks in advance.

Regards,
Little Jimi

Code follows:

    
            function performSearch() 
        
            { 
        
                SelectorService.GetData(0,10000000, 
        
                   ... [snip] ..., 
        
                   UpdateGrid, SearchFailed); 
        
            } 
        
            function UpdateGrid(result) 
        
            { 
        
                var tableView = $find("<%= RadGrid1.ClientID %>").get_masterTableView(); 
        
                tableView.set_dataSource(result); 
        
                tableView.dataBind();                 
        
            }

    
                    <asp:Panel ID="GridPanel" runat="server" Style="font-size: x-small; clear: both; 
        
                        padding: 4px 2px 2px 2px;" ScrollBars="Auto" Height="200px" Width="444px"> 
        
                        <Telerik:RadGrid ID="RadGrid1" runat="server" SkinID="Selector" EnableViewState="false" 
        
                            AllowPaging="true" AllowSorting="True" AllowFilteringByColumn="true" GridLines="None" 
        
                            AutoGenerateColumns="true" OnColumnCreated="RadGrid1_ColumnCreated"> 
        
                            <ClientSettings> 
        
                                <ClientEvents OnRowSelected="RowSelected" OnRowDblClick="RowDblClick" /> 
        
                                <Selecting AllowRowSelect="true" EnableDragToSelectRows="true" /> 
        
                            </ClientSettings> 
        
                        </Telerik:RadGrid> 
        
                    </asp:Panel>

Hello,

When the grid is bound client-side you can access its items only on the client as they are created on the client. On the other hand on the server the grid is not bound, just declared and no items are created there.
If you want to manipulate the grid on the server, you need to bind it server-side. Or with the client-side bound grid, you can try using client code to achieve your goal.

It will also be null, and the grid's "GridCreated" client-side event will never be fired, if the grid's MasterTableView does not have an "ID" defined. If your grid was created in the markup of the Page/UserControl, you will have to add Code to the Page/UserControl's "Init" event and set the ID from the code-behind because you are NOT allowed to enter it in markup. This is probably the root cause of the whole thing, because all other Telerik controls allow you to add the ID property in markup (take the RadDatePicker.DateInput control for example).
