Hi All,

I'm using 3 text boxes for allowing user selecting different ranges. I want to perform below validations on three text boxes.

1.User should enter a value (i.e. a valid number,doesn't allow to enter zero,decimal numbers and negative numbers) in 1st text box.

2. 2nd text box value should be greater than 1st text box.

3. 3rd text box value should be greater than 2nd text box.

I want to perform validations on client side only using JavaScript. If anything goes wrong I want to populate a message box.

How can I do this?

Regards,

NSJ

Home assignment? Interview test? Why not doing it with your own hands -- any valid reason?

Solution 1

Why you are trying to write your own javascript where ASP.NET Provides all the Inbuilt validation which you have required.
