Hi.

I'm using GridDropDownColumn to display and edit values in grid:

1.<telerik:GridDropDownColumn DataField="MYFIELD" HeaderText="Entity" UniqueName="MYFIELD"
2.    DataSourceID="EntityDataSource" ListValueField="ID" ListTextField="NAME"
          EnableEmptyListItem="true">
4.</telerik:GridDropDownColumn>

and ObjectDataSource for show human-readable value of "MY_FIELD" column:
1.<asp:ObjectDataSource ID="EntityDataSource" runat="server" SelectMethod="GetEntityList" 
2.TypeName="..."/>

When i;n group grid by this column - in grid headers shown "ID" value:
"MYFIELD: 45".
How i may to show "NAME" field in groups header?

Hi Yerlan,

You can have complete control over the display of the fields in a GridGroupHeaderItem and even perform calculations and display the results in the group header.

Additional information is available here:

Pavlina, thanks for response.

I'm readed links - adding dummy column to dataset looks easier, cause to my little coding expirience:)

Yerlan,

I'm having the exact same problem, and the link provided is no help.  How did you solve this issue? I guess what I need to know is how to grab the "ListTextField" in  ItemDataBound.

Thanks,
J

Hi Jason,

I suggest that you review Customizing GridGroupHeaderItem help article which elaborates on this subject and see if it helps to achieve your goal.

Pavlina,

I've seen that. but that method assumes that I want my grid grouped on page load, and i dont.  What i'd like to know is how i can grab the listtextfield property?

Hello Jason,

Please refer to the below help article for more information about the mechanism which RadGrid uses to present values for GridDropDownColumn:
