Question

I’ve got a grid view where I am trying to set the fore color from a database string which contains HTML Code. I tried this:

<asp:TemplateField HeaderText="Validation">
                                <ItemTemplate>
                                    <asp:Label ID="lblValidationItem" runat="server" ToolTip="Type of validation."
                                        Text='<%# DataBinder.Eval(Container, "DataItem.ValidationItem") %>' Font-Bold="true" ForeColor='<%# System.Drawing.ColorTranslator.FromHtml(Eval("HTMLColor")) %>'></asp:Label>
                                </ItemTemplate>
                                 <FooterStyle HorizontalAlign="Center" />
                                 <HeaderStyle HorizontalAlign="Center" />
                                 <ItemStyle HorizontalAlign="Center" />
                            </asp:TemplateField>

But it says FromHtml has some invalid parameters?

Answer 1

Eval returns an “Object”. You need to cast it to a string:

<ItemTemplate>
   <asp:Label ID="lblValidationItem" runat="server" ToolTip="Type of validation."
                                        Text='<%# Eval("DataItem.ValidationItem") %>' Font-Bold="true" ForeColor='<%# System.Drawing.ColorTranslator.FromHtml((string)Eval("HTMLColor")) %>'></asp:Label>
</ItemTemplate>
