Hi,

I cannot get an error icon to display when a business rule fails and is associated with a column in a grid view. The GridView column is defined like this:

                                    < ItemTemplate>
                                        < mm:mmLabel ID="lblSumAssured" runat="server" AccessLevel="Full" BindingProperty="Text"
                                            ControlID="00000000-0000-0000-0000-000000000000" IsPostBack="False" SecuritySetup="True"
                                            Text='< %# Bind("SumAssured") % >'></mm:mmLabel>
                                    < /ItemTemplate>
                                    < EditItemTemplate>
                                        < mm:mmTextBox ID="txtRiderSumAssured" runat="server" Width="100%" Text='< %# Bind("SumAssured") % >'
                                            AutoPostBack="true" OnTextChanged="txtRiderSumAssured_TextChanged"></mm:mmTextBox><br />
                                    < /EditItemTemplate>

My rule has this in it:

this.AddErrorProviderBrokenRule("SumAssured", message);

The rule fails, yet no icon shows up in the grid view.

How does one achieve this?
