GroupByExpression with fixed or Enum values

[Delvis]

I have  a GridTemplateColumn bind to “State” data field and the values are fixed or Enum type:

<telerik:GridTemplateColumn DataField="State" DataType="System.Byte" DefaultInsertValue="1"

    UniqueName="StateColumn" GroupByExpression="State Group By State">

    <EditItemTemplate>

        <telerik:RadComboBox ID="StateRadComboBox" runat="server"

SelectedValue='<%#Bind("State")%>'>

            <Items>

                <telerik:RadComboBoxItem runat="server" Text="Active" Value="1" />

                <telerik:RadComboBoxItem runat="server" Text="Inactive" Value="2" />

                <telerik:RadComboBoxItem runat="server" Text="Erased" Value="3" />

                <telerik:RadComboBoxItem runat="server" Text="Pendent" Value="4" />

            </Items>

        </telerik:RadComboBox>

    </EditItemTemplate>

    <ItemTemplate>

        <asp:Label ID="StateLabel" runat="server"

Text='<%# … a logic to get text based on numeric value '></asp:Label>

    </ItemTemplate>

</telerik:GridTemplateColumn>

When forms a group show the numerical value (State: 1, State: 2, State: 3 or State: 4). How can I show your description instead of the numerical value (State: Active, State: Inactive, State: Erased or State: Pendent)?

 

I have the same problem when use GridDropDownColumn and ObjectDataSource:

<telerik:GridDropDownColumn DataField="State" DataSourceID="StateObjectDataSource"

    ListTextField="TextValue" ListValueField="ByteValue" UniqueName="StateColumn"

    DataType="System.Byte">

</telerik:GridDropDownColumn>

Any help?

Hi Delvis,

When you set the GroupByExpression property for a GridTemplateColumn instance, a common problem is that RadGrid cannot get the value from the header text for that column and display it in the GroupHeaderItem. More about grouping could be found at the following help article.
Additionally I prepared a small sample and attached it to this forum post. Give it a try and let me know about the result.

Hi Kostadin,

I appreciate your response. The example I provided does not solve the problem I have. I need an example based on my scenario.

Thanks,

Delvis

Hi Delvis,

I prepared a small sample based on your code and attached it to this thread.. Give it a try and let me know how it differs from your real setup.
