Looping GridView Cell values

I am trying to loop though a GridView and read values from the cells. I have no problem reading from a bound field, but how do i read from a Template field, no other controls exist inside these template fields.

I want to avoid using a label or other controls.


for (int i = 0; i < this.gv.PageCount; i++)
{
    foreach (GridViewRow row in this.gv.Rows)
                {
                        for (int j = 0; j < 6; j++)
                        {
                            row.Cells[j].Text
                         }
                 }
}

Can you post sample markup of your templates?

Templates contains static HTML, Web controls, and data-binding syntax so that gridview can render it, thus you need a control to get the information that is displayed, for example check:

Here is the HTML markup, the bound field gets the data correctly, but the ItemTemplate does not, you are correct about using a control, but i am trying to avoid changing the HTML code.

<asp:BoundField DataField="EmployeeName" HeaderText="Employee Name" SortExpression="EmployeeName" />
                
                <asp:TemplateField HeaderText="Average Time<br/>(in hours)" FooterStyle-Font-Bold="True"  SortExpression="AverageTime" >
                <ItemTemplate>
                  <%# GetAverageTime(Eval("AverageTime").ToString())%>
                </ItemTemplate>
                <FooterTemplate>
                  <%# GetTotalAverageTime()%>
                </FooterTemplate>
                    <FooterStyle Font-Bold="True" />
                </asp:TemplateField>

In this case you need to use a asp.net label, the change is required because the FindControl method will not help you to get the information.
    <ItemTemplate>
        <asp:Label ID="Label1" runat="server"
            Text='<%# GetAverageTime(Eval("AverageTime").ToString()) %>'></asp:Label>
    </ItemTemplate>

I was trying to avoid using a label, but that was the only option available. Thanks!
