Copy One Textbox to another Textbox while User entering data

Thanks Niradip,

I dont think it is the proper way to do it. You need to call the function on 'OnBlur' event of textbox2.(incase of coping the textbox2 data in textbox1).

syntax should be like this:

This will not work for me.
Because my textboxes are in the ContentPlaceHolder which is in the MasterPage.
My javascript function for copying textbox value is as follows.


The above code is given in the .aspx page
Now, I have TextBox1 and TextBox2 in my ContentPlaceHolder called MainContent.
I want to pass these two textboxes to the above function.
I could not find a solution yet.
I have 6 textboxes like this. That is why I am trying to pass the text box to the function. Otherwise I will
have to make 6 functions like this which looks bad.

Hi

Here is solution

 Goto  TextChanged Event  for CompanyAddress Text Box and write below

  BillingAddress.text=CompanyAddress.text
