Hi,

Is there anyway I can hide the expand/collapse icons based on a value calculated in the GridGroupByExpression?

For example I want to hide the icon if the the GroupByField 'Count' aggregate = 0:

<telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="RadAjaxLoadingPanel1">

<telerik:RadGrid ID="rdgSurveys" runat="server" AllowPaging="false" Skin="Office2010Silver"

OnNeedDataSource="rdgSurveys_NeedDataSource" OnItemDataBound="rdgSurveys_ItemDataBound"

OnItemCreated="rdgSurveys_ItemCreated">

<MasterTableView AutoGenerateColumns="False" HeaderStyle-HorizontalAlign="Center" HierarchyDefaultExpanded="false">

<GroupByExpressions>

<telerik:GridGroupByExpression>

<SelectFields>

<telerik:GridGroupByField FieldName="Ref" FieldAlias="Survey" />

<telerik:GridGroupByField FieldAlias="Count" FieldName="SumField" Aggregate="Sum" />

</SelectFields>

<GroupByFields>

<telerik:GridGroupByField FieldName="Ref" SortOrder="Ascending"></telerik:GridGroupByField>

</GroupByFields>

</telerik:GridGroupByExpression>

</GroupByExpressions>

<Columns>

<telerik:GridBoundColumn DataField="DateCreated" DataType="System.DateTime" HeaderText="Date Created"

UniqueName="DateCreated" DataFormatString="{0:dd MMM yyy hh:mm}" />

<telerik:GridBoundColumn DataField="Version" DataType="System.String" HeaderText="Version"

UniqueName="Version" />

<telerik:GridBoundColumn DataField="Respondent" DataType="System.String" HeaderText="Completed By"

UniqueName="Respondent" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

</telerik:RadAjaxPanel>
