[Solved] Self-referencing Hierarchy

[Ryan C]

Reffering to this demo:
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/selfreferencing/defaultcs.aspx

Can anyone please indicate how I can hide the id columns?

 

 

<telerik:RadGrid ID="RadGrid1" runat="server" DataSourceID="SqlDataSource1" OnColumnCreated="RadGrid1_ColumnCreated"

 

 

 

OnItemCreated="RadGrid1_ItemCreated" OnItemDataBound="RadGrid1_ItemDataBound"

<MasterTableView HierarchyDefaultExpanded="false" HierarchyLoadMode="Client" AllowSorting="true"

 

 

 

DataKeyNames="id, parentid" Width="100%" FilterExpression="id=1">

 

 

 

 

 

<SelfHierarchySettings ParentKeyName="parentid" KeyName="id" />

 

 

 

 

 

<Columns>

 

 

 

 

 

<telerik:GridTemplateColumn UniqueName="TemplateEditColumn">

 

 

 

 

 

<ItemTemplate>

 

 

 

 

 

<asp:HyperLink ID="EditLink" runat="server" Text="Edit"></asp:HyperLink>

 

 

 

 

 

</ItemTemplate>

 

 

 

 

 

</telerik:GridTemplateColumn>

 

 

 

 

 

</Columns>

 

 

 

 

 

</MasterTableView>

 

 

 

 

 

<ClientSettings AllowExpandCollapse="true">

 

 

 

</ClientSettings>

 

 

 

 

 

</telerik:RadGrid>

Hello Ryan C,

You can intercept the ColumnCreated server event of the grid (raised for auto-generated columns), determine the id column by its UniqueName value and set its Display or Visible property to false. See the information from this documentation article for further details.
