Solution 1

You need to bind the CheckBox you just added to something meaningful. Make sure that you are binding it correctly.

Hi,
It sounds like you are using CheckBoxField and you have assigned a DataField property to it. Try this:

ASP.NET

<asp:templatefield headertext="Check" xmlns:asp="#unknown">                            
    <itemtemplate>
        <asp:checkbox id="chkIndicator" runat="server" />
    </itemtemplate>
</asp:templatefield>
