How to use javascript validation code for asp.net tools???

Put Following javaScript In Section  of .aspx page

 

take  2 TextBox "TextBox1 and TextBox2

then Set CustomValidator  Control's  ControlToValidate Propertie to  "TextBox2"

and ClientValidationFunction="CheckText"


Validator checks Text Box for "Hello" Text  if Not found  text  = "Hello" Will Display Error

if you Want to Validate that if TextBox is Blank then Also Make ValidateEmptyText propertie of CustomValidator  to  true
