Using Repeater inside a Repeater.

Simply instead of the following line

 

<asp:repeater id="childRepeater" runat="server"                      datasource='<%# ((DataRowView)Container.DataItem)       .Row.GetChildRows("myrelation") %>' >  

Use below line.

  

<asp:repeater id="childRepeater" runat="server"                      datasource='<%# GetChildData(databinder.Eval(Container.DataItem,"PKID")) %>' > 

 and in code behind file write this following function
  

public function GetChildData(byval pkid as long) as datatable dim dt as datatable  ' get your result in db by PKID or any other filteration return dt end function  here is the example  .... http://support.microsoft.com/default.aspx?scid=kb;en-us;306154
