Displaying Custom Messages / Images with NULL Value in ASP.NET GridView

When we  bind some data source with GridView which contains some fields with NULL value,  ASP.NET renders them as Blank.

Sometimes developers use GridView_RowDataBound() to override the NULL value with proper message. But Instead of overriding the value, we can use NullDisplayText to display proper message when the value for that particular field is NULL .

Once we mentioned NullDisplayText=”No Data” for every field for that Bound Filed which having NULL value will be replace by “No Data”

Even we can customize the Text with HTML Formatting as shown in below.

One more interesting point is, we  can also display Images for NULL Value
