Question

The (pseudo code) expression within the “Visible”-Tag of the TemplateField is what I like to achieve, any ideas?
I´d really love to do it declaratively. No OnRowCreated event handling, Cells[x], …

            <asp:GridView ID="GridViewTest" runat="server" AutoGenerateColumns="false">
                <Columns>
                    <asp:BoundField DataField="MyProperty" HeaderText="My Property" />
                    <asp:TemplateField Visible="<%# MyProperty == 'VisibleString' %>">
                        <ItemTemplate>
                            <asp:ImageButton ID="ImageButton1" runat="server" AlternateText="" ImageUrl="" OnClick="ImageButton1_Click" />
                        </ItemTemplate>
                    </asp:TemplateField>
                </Columns>
            </asp:GridView>

It was not possible to do that on the TemplateField column itself because it has no DataBinding support. I had to do it within the ImageButton. Now it works perfectly:

<asp:ImageButton Visible='<%# Eval("MyProperty") == "VisibleString" %>' [...] />
