Hi All

I have Radgrid setup to allow the user to drag columns into the header for group by.

The problem is some of  my groupable columns use the dropdownlist and when I group by them I see the stored value in the group by header (eg ID) rather than the display value.

How do I get round this?

thx

Hello,

In most scenarios GridDropDownColumn ListTextField property is not part of the grid data source. For example if you have grid bound to Orders and a GridDropDownColumn with ListValueField set to "CustomerID" you will use  probably "CompanyName" for ListTextField property to display a bit more friendly info for the user. In this case since "CompanyName" is not part of Orders table you will not able to group by this however if you include an additional (computed) field in your query to return "CompanyName" as part of Order table you will be able to group on this column. Another possible approach is to retrieve values on the fly using ItemDataBound event and modify directly GridGroupHeaderItem similar to this example:
