Hi
I am using in-line <GroupByExpression> and it is working well apart from the fact that I can't get the Group Header to show up.

The code I am using is below:

    
               <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" GridLines="None">  
        
                    <HeaderContextMenu CausesValidation="False">  
        
                        <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                    </HeaderContextMenu> 
        
                    <MasterTableView GroupLoadMode="Client">  
        
                            <Columns> 
        
                            <telerik:GridBoundColumn  datafield="ThreadID" datatype="System.Int32" headertext="ThreadID" 
        
                                sortexpression="ThreadID" uniquename="ThreadID" readonly="True" visible="False">  
        
                             </telerik:GridBoundColumn> 
        
                            <telerik:GridBoundColumn  datafield="Title" datatype="System.Int32" headertext="Title" 
        
                                sortexpression="Title" uniquename="Title" readonly="True">  
        
                             </telerik:GridBoundColumn> 
        
                            <telerik:GridBoundColumn  datafield="Type" datatype="System.Int32" headertext="Type" 
        
                                sortexpression="Type" uniquename="Type" readonly="True">  
        
                             </telerik:GridBoundColumn> 
        
                            <telerik:GridBoundColumn  datafield="Publish" datatype="System.Int32" headertext="Publish" 
        
                                sortexpression="Publish" uniquename="Publish" readonly="True" visible="False">  
        
                             </telerik:GridBoundColumn> 
        
                               </Columns> 
        
                        <GroupByExpressions> 
        
                            <telerik:GridGroupByExpression> 
        
                                <GroupByFields> 
        
                                    <telerik:GridGroupByField FieldAlias="Type" FieldName="Type" FormatString="" HeaderText="Type" /> 
        
                                </GroupByFields> 
        
                            </telerik:GridGroupByExpression> 
        
                        </GroupByExpressions> 
        
                    </MasterTableView> 
        
                    <FilterMenu> 
        
                        <CollapseAnimation Duration="200" Type="OutQuint" /> 
        
                    </FilterMenu> 
        
                    <ValidationSettings EnableValidation="False" /> 
        
                </telerik:RadGrid>

Any help appreciated.

Thanks

Hello Richard,

The SelectFields collection determines the information that is displayed in the group header. So inorder to display the GroupHeader you would have to set the GridGroupByExpression>SelectFields as shown below:
aspx:

    
            <GroupByExpressions> 
        
                <telerik:GridGroupByExpression> 
        
                     <GroupByFields> 
        
                            <telerik:GridGroupByField FieldAlias="Type" FieldName="Type" FormatString="" HeaderText="Type"/>               
        
                     </GroupByFields> 
        
                     <SelectFields> 
        
                           <telerik:GridGroupByField FieldAlias="Type" FieldName="Type"/>               
        
                     </SelectFields> 
        
                </telerik:GridGroupByExpression> 
        
            </GroupByExpressions>

Thanks
Princy.

group3-and-4-do-not-sum-up-total-or-display-header.png

Hi Princy,

I have a similiar issue, i have four categories groups. I see the headertext and totals for the first two. the 3rd and 4th group i cannot see the title. I am worried that its not summing the groupbyexpression because total is always 0, but it should be (2) and (2). I will paste my radgrid code below.

<telerik:RadGrid RenderMode="Lightweight" ID="RadGrid2" runat="server" PageSize="30" AutoGenerateColumns="False"
