Question

How do i change the DataItem “AmountCollected” in a GridView to something else in Code Behind. I want to change the DataItem to Balance depending on some condition and i was wondering if it can be done?!! This is using VS 2005 using c# and HTML.

Thanks in Advance!!

<asp:TemplateField ItemStyle-Width="70" ItemStyle-HorizontalAlign="Center">
<ItemTemplate>
     $<asp:Label ID="lblTotalCollected" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"AmountCollected") %>'></asp:Label>
</ItemTemplate>

Set up an RowDataBound event for the GridView. That event will run for each item in your datasource, and you can modify each row based on your criteria.

public void myGridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType != DataControlRowType.DataRow)
    {
        return;
    }

    Label myLabel = e.Row.FindControl("lblTotalCollected") as Label;
    MyClass myDataItem = e.Row.DataItem as MyClass;
    if(...)
    {
        myLabel.Text = myDataItem.Balance;
    }
    else
    {
        myLabel.Text = myDataItem.AmountCollected;
    }
}
