Hi,

I'm just evaluating the RadControls an trying to figure out how to get the value of a cell from a RadGrid if I use ItemTemplates.
I read this article from the manual but it doesn't work as espected.
This is my grid and JS code:

    
                    function RowSelected(sender, eventArgs) { 
        
                        var MasterTable = sender.get_masterTableView(); 
        
                        var row = eventArgs.get_gridDataItem(); 
        
                        alert(MasterTable.getCellByColumnUniqueName(row, "ID").innerHTML); 
        
                    }

    
            <telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" GridLines="None" 
        
                            Skin="Office2007" ShowHeader="False"> 
        
                            <ClientSettings> 
        
                                <Selecting AllowRowSelect="True" /> 
        
                                <ClientEvents OnRowSelected="RowSelected" OnRowCreated="RowCreated" /> 
        
                            </ClientSettings> 
        
                            <MasterTableView AllowAutomaticUpdates="True" DataSourceID="SqlDataSource1" HorizontalAlign="Left"> 
        
                                <Columns> 
        
                                    <telerik:GridTemplateColumn UniqueName="Other"> 
        
                                        <ItemTemplate> 
        
                                            <span style="display: block; float: left;"> 
        
                                                <%# Eval("by")%></span> <span style="display: block; float: right;"> 
        
                                                    <%# Eval("date")%></span> 
        
                                            <br /> 
        
                                            <span style="font-weight: bold;"> 
        
                                                <%# Eval("subject")%> 
        
                                            </span> 
        
                                        </ItemTemplate> 
        
                                    </telerik:GridTemplateColumn> 
        
                                    <telerik:GridTemplateColumn UniqueName="ID"> 
        
                                        <ItemTemplate> 
        
                                            <%# Eval("ID")%> 
        
                                        </ItemTemplate> 
        
                                    </telerik:GridTemplateColumn> 
        
                                </Columns> 
        
                            </MasterTableView> 
        
                        </telerik:RadGrid>

I'm able to get the id, but the problem is, that all columns are displayed (I retrieve about 10 columns from DB while showing only 3) using the markup but I need to display a selection of them with a custom template and retrieving data of other columns which are not displayed (for instance ID).
If I define a new ItemTemplate after the closing <columns> tag the grid is displayed correctly but I cant access the id.

Cutting a long story short I'm looking for a clean and clientside way to access the content of specific cells which are not displayed.
I don't like something like <span style="display:none"> <%# Eval("ID")%></span> and MasterTable.getCellByColumnUniqueName(row, "Info").document.getElementByTagName('span')[int].innerHTML because this is a dirty workaround.

Any help is highly appreciated.

Kind regards Jay
