c# - Server tag : The server tag is not well formed

Question

I got this error and I don't know what's wrong with my code...here it is:

<asp:LinkButton runat="server" ID="lnkbtnPDFPreview" Text="Preview" 
  CommandArgument='<%# DataBinder.Eval(Container.DataItem,"productID") %>'                                
  CommandName="<%# DataBinder.Eval(Container.DataItem,"documentID") %>">
</asp:LinkButton>

Answer 1

You are using " in the attribute value delimiter and inside the attribute:

CommandName="<%# DataBinder.Eval(Container.DataItem,"documentID") %>"

Change the outer delimiter to ' as already done for CommandArgument:

CommandName='<%# DataBinder.Eval(Container.DataItem,"documentID") %>'
