Answer 1

Hey,

Why not use the TemplateField control in the markup, and define the checkbox in the template instead? It would be easier to manage...

<asp:GridVIew ...>

  <Columns>
     <asp:TemplateField ..>
        <asp:CheckBox .. />
     </asp:TemplateField>
  </Columns>
</asp:GridVIew>

And just set everything up in the markup

Try using OnRowDataBound event on the gridview. You can use it to specify what control you want to use for each row. Here's a link that explains it with an example.
