getting in textbox while retrieving

hi,
I am using sql server database. In my table i am having three columns namely Name, age and salary. I am having three textboxes in my webform to retrieve data from the database.The column salary has no value in the database. When i retrieve the values in to textbox controls, i am getting in my textbox for the salary field.

How to overcome this.?

pls help

Are you HTML Encoding the values that appear in the TextBox?|||

(1) It is a good idea to default 0 in the column.(2) You could do a convert to double in the front end.

If you still have problems please post some code as to how you are populating the textbox.
