Conversion Of Html To Pdf

I am converting an html into pdf, I have observed that the pdf is getting generated but not properly. i.e. the Datalist2 and the gridview2 present inside the Datalist2 is not getting populated.

<table id="tblReport" runat="server">
<asp:DataList ID="DataList1" runat="server">
<ItemTemplate>
<tr>
<td>
<asp:Label ID="lbl1" runat="server"> </asp:Label>
</td>
</tr>
<tr>
<td>
<asp:GridView ID="GridView1" runat="server">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="lbl1" runat="server"> </asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</td>..............
