GridView: convert data before bindind to GridView
<p>My GridView using following data binding syntax to bind data. 
I hope do data conversion before it is really bound to GridView. For example, <strong>if the VendorID int property (I use a List as data source) is 0, I wish showing empty string on that field.</strong> 
What kind of event I could exploit? And if you could suggest any code sample?</p>

<p>Thanks a lot.</p>

<pre><code>        &lt;asp:TemplateField HeaderText="Vendor ID"&gt;
            &lt;ItemStyle Width="1%" BorderColor="#efefef" BorderWidth="1px" /&gt;
            &lt;ItemTemplate&gt;
                &lt;asp:Label runat="server" ID="lblNo" Text='&lt;%# Bind("VendorID") %&gt;'&gt;&lt;/asp:Label&gt;
            &lt;/ItemTemplate&gt;
            &lt;HeaderStyle BorderColor="#efefef" /&gt;
        &lt;/asp:TemplateField&gt;
</code></pre>
