Help with Grid View

I have a page that has drop down list and a user control

The user control generate graphs and data grids for web enabled reports.
Code:
        protected void Page_Load(object sender, EventArgs e)
        {
            uc_report.sChartType = ddlChartType.SelectedValue;
        }

Inside my UC i have
Code:
<asp:UpdatePanel ID="FusionChartsUP" runat="server">
    <ContentTemplate>
        <asp:Panel ID="pnlChart" runat="server" Width="950px" Height="100%" ></asp:Panel>

        <asp:Panel ID="pnlData" runat="server" Width="950px" Height="100%" >  </asp:Panel>
        <asp:GridView ID="gvData" runat="server" ForeColor="#333333">
            <AlternatingRowStyle BackColor="White" ForeColor="#333333" />
            <RowStyle BackColor="#F7F6F3" ForeColor="#333333" />
        </asp:GridView>

    </ContentTemplate>
</asp:UpdatePanel>

I have 17 different reports. However, here is what is happening. As I change the drop down list for each chart type, the graph is generated and the grid is created. I am adding the grids to the pnlData but when I try to loop through the cells and format them, it only seems to work the first time.

Any ideas or suggestions? I have tried a bunch of different things, and not sure what I am doing wrong here. I am guessing this is because of the update panel or I have something setup wrong with the update panel.

What do you mean it only seems to work the first time? Do you get an error(s)?
 
No errors but If i choose a different version of the report and it runs through the code again. The datatable has the correct values, but the gridview does not get them. If I leave these commented out, the values switch.

Code:
//dResult = Convert.ToDecimal(gvData_Counts_Observations_Pct.Rows[x].Cells[i].Text);
//gvData_Counts_Observations_Pct.Rows[x].Cells[i].Text = String.Format("{0:p0}", dResult);
 
What happens when you trace through the code you commented out, what values do you see?
