Hi,

i'm currently trying to do a hierarchy grid view on more than 2 levels and it isn't working.

The grid is working fine if I use two levels but as soon as i add another one the expand on the grid show nothing after the second level

Here's the code of the grid :

<telerik:RadGrid ID="rg_VL" runat="server"

DataSourceID="SqlDataSourceCODPRO1"

AllowSorting="True" AllowMultiRowSelection="False" AllowPaging="False" GridLines="None">

<MasterTableView AutoGenerateColumns="false" DataSourceID="SqlDataSourceCODPRO1" DataKeyNames="CODPRO1">

<DetailTables>

<telerik:GridTableView DataKeyNames="CODPRO2" DataSourceID="SqlDataSourceCODPRO2" runat="server">

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="CODPRO1" MasterKeyField="CODPRO1" />

</ParentTableRelation>

<DetailTables>

<telerik:GridTableView DataKeyNames="CODPRO3" DataSourceID="SqlDataSourceCODPRO3" runat="server">

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="CODPRO2" MasterKeyField="CODPRO2" />

</ParentTableRelation>

<DetailTables>

<telerik:GridTableView DataKeyNames="CODPRO4" DataSourceID="SqlDataSourceCODPRO4" runat="server">

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="CODPRO3" MasterKeyField="CODPRO3" />

</ParentTableRelation>

<DetailTables>

<telerik:GridTableView DataKeyNames="CODPRO5" DataSourceID="SqlDataSourceCODPRO5" runat="server">

<ParentTableRelation>

<telerik:GridRelationFields DetailKeyField="CODPRO4" MasterKeyField="CODPRO4" />

</ParentTableRelation>

<Columns>

<telerik:GridBoundColumn SortExpression="CODPRO5" HeaderText="CODPRO5" HeaderButtonType="TextButton"

DataField="CODPRO5" UniqueName="CODPRO5">

</telerik:GridBoundColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridBoundColumn SortExpression="CODPRO4" HeaderText="CODPRO4" HeaderButtonType="TextButton"

DataField="CODPRO4" UniqueName="CODPRO4">

</telerik:GridBoundColumn>

</Columns>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridBoundColumn SortExpression="CODPRO3" HeaderText="CODPRO3" HeaderButtonType="TextButton"

DataField="CODPRO3" UniqueName="CODPRO3">

</telerik:GridBoundColumn>

</Columns>

<SortExpressions>

<telerik:GridSortExpression FieldName="CODPRO3"></telerik:GridSortExpression>

</SortExpressions>

</telerik:GridTableView>

</DetailTables>

<Columns>

<%--<telerik:GridBoundColumn SortExpression="CODPRO2" HeaderText="CODPRO2" HeaderButtonType="TextButton"

DataField="CODPRO2" UniqueName="CODPRO2">

</telerik:GridBoundColumn>--%>

</Columns>

<SortExpressions>

<telerik:GridSortExpression FieldName="CODPRO2"></telerik:GridSortExpression>

</SortExpressions>

</telerik:GridTableView>

</DetailTables>

<Columns>

<telerik:GridBoundColumn SortExpression="CODPRO1" HeaderText="CODPRO1" HeaderButtonType="TextButton"

DataField="CODPRO1" UniqueName="CODPRO1">

</telerik:GridBoundColumn>

</Columns>

<SortExpressions>

<telerik:GridSortExpression FieldName="CODPRO1"></telerik:GridSortExpression>

</SortExpressions>

</MasterTableView>

</telerik:RadGrid>

And the code of my datasources :

<asp:SqlDataSource ID="SqlDataSourceCODPRO1" ConnectionString="<%$ ConnectionStrings:bddBigJimWeb %>"

ProviderName="System.Data.OracleClient" SelectCommand="SELECT DISTINCT CODPRO1 FROM VENTES_LACH_REG ORDER BY CODPRO1"

runat="server">

</asp:SqlDataSource>

<asp:SqlDataSource ID="SqlDataSourceCODPRO2" ConnectionString="<%$ ConnectionStrings:bddBigJimWeb %>"

ProviderName="System.Data.OracleClient" SelectCommand="SELECT DISTINCT CODPRO2 FROM VENTES_LACH_REG Where CODPRO1 = :CODPRO1"

runat="server">

<SelectParameters>

<asp:SessionParameter Name="CODPRO1" SessionField="CODPRO1" Type="string">

</asp:SessionParameter>

</SelectParameters>

</asp:SqlDataSource>

<asp:SqlDataSource ID="SqlDataSourceCODPRO3" ConnectionString="<%$ ConnectionStrings:bddBigJimWeb %>"

ProviderName="System.Data.OracleClient" SelectCommand="SELECT DISTINCT CODPRO3 FROM VENTES_LACH_REG CODPRO1 = :CODPRO1 AND CODPRO2 = :CODPRO2"

runat="server">

<SelectParameters>

<asp:SessionParameter Name="CODPRO1" SessionField="CODPRO1" Type="string">

</asp:SessionParameter>

<asp:SessionParameter Name="CODPRO2" SessionField="CODPRO2" Type="string">

</asp:SessionParameter>

</SelectParameters>

</asp:SqlDataSource>

<asp:SqlDataSource ID="SqlDataSourceCODPRO4" ConnectionString="<%$ ConnectionStrings:bddBigJimWeb %>"

ProviderName="System.Data.OracleClient" SelectCommand="SELECT DISTINCT CODPRO4 FROM VENTES_LACH_REG WHERE CODPRO1 = :CODPRO1 AND CODPRO2 = :CODPRO2 AND CODPRO3 = :CODPRO3"

runat="server">

<SelectParameters>

<asp:SessionParameter Name="CODPRO1" SessionField="CODPRO1" Type="string">

</asp:SessionParameter>

<asp:SessionParameter Name="CODPRO2" SessionField="CODPRO2" Type="string">

</asp:SessionParameter>

<asp:SessionParameter Name="CODPRO3" SessionField="CODPRO3" Type="string">

</asp:SessionParameter>

</SelectParameters>

</asp:SqlDataSource>

<asp:SqlDataSource ID="SqlDataSourceCODPRO5" ConnectionString="<%$ ConnectionStrings:bddBigJimWeb %>"

ProviderName="System.Data.OracleClient" SelectCommand="SELECT DISTINCT CODPRO5 FROM VENTES_LACH_REG WHERE CODPRO1 = :CODPRO1 AND CODPRO2 = :CODPRO2 AND CODPRO3 = :CODPRO3 AND CODPRO4 = :CODPRO4"

runat="server">

<SelectParameters>

<asp:SessionParameter Name="CODPRO1" SessionField="CODPRO1" Type="string">

</asp:SessionParameter>

<asp:SessionParameter Name="CODPRO2" SessionField="CODPRO2" Type="string">

</asp:SessionParameter>

<asp:SessionParameter Name="CODPRO3" SessionField="CODPRO3" Type="string">

</asp:SessionParameter>

<asp:SessionParameter Name="CODPRO4" SessionField="CODPRO4" Type="string">

</asp:SessionParameter>

</SelectParameters>

</asp:SqlDataSource>

Do you know why I have no errors shown on my web page but no hirarchical level after the second level ?
