When I DataBind or Rebind by RadGraid which has a groupbyexpression. The format gets lost. I have to do a full postback to see the group fiends format correctly.
<GroupByExpressions>
<telerik:GridGroupByExpression>
<SelectFields>
<telerik:GridGroupByField FieldAlias=" " FieldName="ActionDay" FormatString="{0:M/d}" HeaderValueSeparator=""
HeaderText="">
</telerik:GridGroupByField>
</SelectFields>

<telerik:GridGroupByField FieldAlias="" SortOrder="Descending" FieldName="ActionDay"
FormatString="{0:M/d}" HeaderText=""></telerik:GridGroupByField>
