1. Not too clear.
2. What have you tried?

Define a KeyPress event and track the letters.

i have a UC Component, in which i have taken a textbox(UserControl.TextBox1.Text).In my Form1 i m using 2 UserControl(UserControl1 and UserControl2).I want the code through which text of UserControl1.TextBox1.Text should show in UserControl2.TextBox1.Text,simultaneouly as i m entering values in UserControl1.TextBox1.Text.

In brief-
1-Suppose i have to write ME,so first i will enter M in UserControl1.TextBox1.Text(here i m entering the values in UserControl1.TextBox1.Text but it should also show in UserControl2.TextBox1.Text) like (on the keypress event of textbox1 --textbox2.text=textbox1.text)

1. Your UserControl needs a custom event: TextBoxTextChanged with its signature like a standard EventHandler[^]. Fire the event whenever the TextBox[^] fires its TextChanged[^] event.
2. Your UserControl needs a public property TextBoxText, too. Implement only the getter part returning the TextBox's current text.

3. The second UserControl needs to subscribe to the first UserControl's TextBoxTextChanged event. Upon firing of the event, an event handler routine will be called. In the event handler, copy text from sender's TextBoxText property (if existing) to this.TextBox1.Text (or whatever it is actually called).
