By | January 27, 2011

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”
