cant bind radmenu

[Teoman Tamer]

Hi,
I am trying to bind radmenu but it gives me  error "This constraint cannot be enabled as not all values have corresponding parent values."

 

 

 

<telerik:RadMenu ID="RadMenu1" Runat="server" DataFieldID="menuid"

 

 

DataFieldParentID="parentid" DataSourceID="SqlDataSource1"

 

 

DataTextField="menuname">

 

 

</telerik:RadMenu>

 

 

<asp:SqlDataSource ID="SqlDataSource1" runat="server"

 

 

ConnectionString="<%$ ConnectionStrings:ConnectionString %>"

 

 

SelectCommand="SELECT menuid,parentid,menuname FROM menu"></asp:SqlDataSource>


Menu Table
-------------------------------------
  menuid       parentid     menuname
------------------------------------
     1        0        Products
     2        1        Servers
     3        1        Desktops
     4        1        Notebooks

Hello Teoman,

Please try to set null for the parentid of root items instead of "0" and let us know how it goes.
