Problems with GroupByExpressions

[Manuel]

Hi,

I have a problem with SortOrder for SelectFields in GridGroupByExpressions when i change to "Descending". Only works for "Ascending". 

When i change to "Descending" i got an error at the designer in VS .NET. i attached an image with the error.

The code for the grid is:

<GroupByExpressions>
                    <telerik:GridGroupByExpression>
                        <GroupByFields>
                            <telerik:GridGroupByField FieldName="OrderNumber" />
                        </GroupByFields>
                        <SelectFields>
                            <telerik:GridGroupByField FieldName="OrderNumber" FieldAlias="OrderNumber" HeaderText="Ordem"
                                SortOrder="Ascending" />
                            <telerik:GridGroupByField FieldName="OrderID" FieldAlias="OrderID" HeaderText="Ítens"
                                Aggregate="Count" />
                            <telerik:GridGroupByField FieldName="ProductAmount" FieldAlias="GroupTotal" Aggregate="Sum"
                                HeaderText="Total" />
                            <telerik:GridGroupByField FieldName="OrderStatus" FieldAlias="OrderStatus" HeaderText="Status" />
                        </SelectFields>
                    </telerik:GridGroupByExpression>
                </GroupByExpressions>

Hello Manuel,

SortOrder specifies how group values are sorted. Its value can be "Ascending" or "Descending". This property is only used for fields in the GroupByFields collection. Also check this help documentation which explains the same.
aspx:

<GroupByExpressions>
     <telerik:GridGroupByExpression>
     <SelectFields>
      <telerik:GridGroupByField FieldName="OrderNumber" />
     </SelectFields>
     <GroupByFields>
      <telerik:GridGroupByField FieldName="OrderNumber" SortOrder="Descending" />
    </GroupByFields>
  </telerik:GridGroupByExpression>
</GroupByExpressions>

Thanks,
Shinu.
