You can use this javascript function Place a HTML text box (here its name is Text1)and onBlur event write a function function abc() { var res=document.getElementById("Text1").value; if(isNaN(res)|| document.getElementById("Text1").value==0) { document.form1.Text1.value=""; } }

Put the validation expression as validationexpression=\d{0,10} its only accepting only integer values in the range 0 to 10 or Change it to ValidationExpression="[0-9]*"

You could use a comparevalidator to check the value is greater than 0

You can use regex to find if the entered data is a "Natural Number". Google will help you find it. Also, make sure that the regex should NOT have a check that text begins with 0. Reason being user can enter 0000003434 which is a valid entry as per your criteria.
