Rad Grid - Group By - DropDownColumn text instead of value

[Justyn]

GridGroupByExpression exp = GridGroupByExpression.Parse("group by " + name);
GridGroupByField field = new GridGroupByField();
field.FieldAlias = "Group";
field.FieldName = name;
exp.SelectFields.Add(field);
rg.MasterTableView.GroupByExpressions.Add(exp);

I have a rad grid that I am creating dynamicaly.
The grid has a drop down box control in it along with other fields such as text.

GridDropDownColumn gdc = new GridDropDownColumn();
gdc.Visible = visible;
gdc.DataField = uniqueName;
gdc.HeaderText = headerText;
gdc.ListTextField = "Value";
gdc.ListValueField = "ListValueId";
gdc.UniqueName = uniqueName;
gdc.DropDownControlType = GridDropDownColumnControlType.DropDownList;

When I group by the drop down column, I get it grouped by the value instead of the text. 

Is there a way to specify which one?

I need value and text to be different so making them the same is not a solution.

Hello Justyn,

This scenario is not currently supported by RadGrid. The GridDropDownColumn can be sorted by the DataField(ListValueField) only.

Hi,

Is this functionality still not supported? I am trying to achieve this.

Thanks in advance.

Hello Alfonso,

To achieve the requested functionality, you can replace the dropdown column with GridTemplateColumn:

<telerik:GridTemplateColumn UniqueName="TemplateColumnName" DataField="TextFieldName">
    <ItemTemplate>
        <asp:Label ID="Label1" runat="server" Text='<%# Eval("TextFieldName") %>'></asp:Label>
    </ItemTemplate>
    <EditItemTemplate>
        <telerik:RadComboBox ID="RadComboBox1" runat="server"
            DataSourceID="SqlDataSource2" DataTextField="TextFieldName"
            DataValueField="ValueFieldName" SelectedValue='<%# Bind("ValueFieldName") %>'>
        </telerik:RadComboBox>
    </EditItemTemplate>
</telerik:GridTemplateColumn>

Hope this helps.
