Question

how to put <%# DataBinder.Eval(Container, "DataItem.Code") %> to string in aspx file?
like <% string str = DataBinder.Eval(Container, "DataItem.Code") %>?
I am getting error The name ‘Container’ does not exist in the current context

Answer 1

You could write a helper function in your code behind which will return the required string:

protected string MyFunction(object item)
{
    ... do some calculations and return a string
}

and then in your view whenever you needed the value you could call this function:

<%# MyFunction(DataBinder.Eval(Container, "DataItem.Code")) %>

This way you no longer need a variable.
