how do I populate gridview label (item template) with function

How do I populate a template field label using a method in code behind?

I attempted this: (in gridview gvCase in aspx page)
<asp:TemplateField HeaderText="case">
                 <ItemTemplate>
                        <asp:Label ID="Label1" runat="server" Text="<%# getCase() %>"></asp:Label>
                    </ItemTemplate>
                 </asp:TemplateField>
[...]
in aspx.cs page

protected string getCases()
    {
        for (int index = 0; index < gvCase.Rows.Count; index++)
        {
            if (gvCase.Rows[index].RowType == DataControlRowType.DataRow)
            {
                strCase = ""; //reset for each row
                strID = gvCase.Rows[index].Cells[1].Text.ToString(); //Cell number 1 is "ID" field or datakey
                if (strID != null)
                {... do some stuff here to retrieve values - this part works}
            }
        }
        return strCase;
    }

However my values are all one row off?

what if you did it on the row databound event? Then you can easily use the findcontrol method to grab your lablel

hmm, now they are two off :-) so when I reverse the logic and try

for (int index = 0; gvCase.Rows.Count +1; index++)

I get an index out of range for

if (gvCase.Rows[index].RowType == DataControlRowType.DataRow)...

yeh the count is going to be the total number of rows, while the index starts at 0. so the last row, if it's 16, will have an index of 15. it looks like you already knew this.

maybe try setting it to run whether it's a datarow or an alternatingrow.
