Pros and Cons of DataBinder.Eval()

Although DataBinder.Eval() function is very easy to use, it imposes performance penality due to late binding. This can be avoided using explicit casting. Following code snippet shows both the approaches:

Using DataBinder:
<%# DataBinder.Eval(Container.DataItem, "TotalAmount", "{0:n}" %>

Using Explicit Casting:
<%# String.Format("{0:n}", ( (DataRow)(Container.DataItem))["TotalAmount"]) %>
