Answer : Nested Gridviews RowDataBound Event Problem

It simple.
What u can do is On the first grid view create its row databound event.
that u know.
NOw for the gridview inside main grid view You have to manually type ur Rowdatabound event for the sub gridview. and it will fire ur sub grid view onrowdatbound event and you can access those variables inside sub gridview with the same way u access in master grid view.

Some example:

<asp:GridView ID="gdProject" runat="server" AutoGenerateColumns="False"
onrowdatabound="gdProject_RowDataBound" Width="100%" >
<Columns>
<asp:TemplateField>
<ItemTemplate>

<asp:Label ID="pid" runat="server" Text='<%# Eval("projectId")%>' Visible="false" ></asp:Label>

<asp:GridView ID="gdTodoList" runat="server" AutoGenerateColumns="false" GridLines="None" onrowdatabound="gdTodoList_RowDataBound" ShowHeader="false">

<asp:Label ID="tid" runat="server" Text='<%# Eval("taskListID")%>' Visible="false"></asp:Label>

</asp:GridView>

</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

IN code behind:

protected void Page_Load(object sender, EventArgs e)
{
gdProject.DataBind();
}

protected void gdProject_RowDataBound(object sender, GridViewRowEventArgs e)
{
GridView gd = new GridView();
Label lblPID = new Label();

gd = (GridView)e.Row.FindControl("gdTodoList");
lblPID = (Label)e.Row.FindControl("pid");

if (gd != null)
{
......
gd.DataBind();
}
}

protected void gdTodoList_RowDataBound(object sender, GridViewRowEventArgs e)
{
Label lblTID = new Label();
lblTID = (Label)e.Row.FindControl("tid");
}
