I have a RadGrid with a datatable as it's source.
I have AllowCustomPaging set to true.

    
                <telerik:RadGrid runat="server" ID="RadGridSearchResults" 
        
                PageSize="50" AllowPaging="true" AllowCustomPaging="true" 
        
                OnNeedDataSource="RadGridSearchResults_NeedDataSource" Skin="Default"> 
        
                <PagerStyle Mode="NextPrevNumericAndAdvanced" /> 
        
                </telerik:RadGrid>

The code for my code behind method RadGridSearchResults_NeedDataSource just fills and returns a datatable with the following columns:

    
                dataTableSearchResults.Columns.Add("recipeId", typeof(string)); 
        
                dataTableSearchResults.Columns.Add("ingredientsIds", typeof(string)); 
        
                dataTableSearchResults.Columns.Add("country", typeof(string)); 
        
                dataTableSearchResults.Columns.Add("author", typeof(string)); 
        
                dataTableSearchResults.Columns.Add("style", typeof(string)); 
        
                dataTableSearchResults.Columns.Add("friendly", typeof(string)); 
        
                dataTableSearchResults.Columns.Add("name", typeof(string));

Once the RadGrid is databound, I run the following:

    
                var expression = GridGroupByExpression.Parse( 
        
                "recipeId [Recipe], count(recipeId) ingredientsIds [Ingredients]
        
                Group By recipeId"); 
        
                this.RadGridSearchResults.MasterTableView.GroupByExpressions.Add(expression); 
        
                this.RadGridSearchResults.GroupingEnabled = true;

I would expect my radgrid to then look like the one they have here once you click on the 'Group by expression' button:

Instead, it looks like this:

After Load

Only looking right after I click the 'sort' button:

After Clicking Sort

Any clue? I even tried invoking sort manually but that was not successful.
