In one of my database project i add 3 textboxes for entering name from user like...First name,Middle name,Last name.I also want to add a mother textbox to show those 3 textbox properties while typing.Such as,when an user type his first name(as example,Ridoy) in First name textbox,that mother textbox will show that!!..similarly after typing middle name(as example,Pal) and last name(as example,Shuvro)...the Mother text box will show the whole name correctly...Ridoy Pal Shuvro..How can i do this?Anyone have a idea..

Thanks for any help.

What you will typically need to do is set up an event listener of some sort. The event listener will detect when the content of one text box has changed, and update the other text box accordingly. The way to do so should be very easy to find in the documentation for whatever toolkit or framework you're using.

If you need a more specific answer, then we first need to know what you're using to make the text boxes. HTML and Javascript? Qt? GTK? Silverlight? Swing?

Thanks for reply...I use C sharp for text boxes.

C# is a programming language, not a GUI toolkit.

There are two official GUI tookits for C#: WPF and WinForms. The second one is older and the only one available on Mono.

For WinForms, you're going to have the TextChanged event on one TextBox modify the Text property of the other one. Knowing how to do so is fundamental to C# programming. There are many tutorials on how to set up the events and delegates needed to make this happen --- including one you can find by following the first link.

I didn't know about that (though I assumed there is some Windows-specific toolkit that C# can use), but there's also GTK+ bindings for C#.
