Is this in ASP.Net or Winforms?

All you need is reading of one short MSDN page on TextBox. I don't know what exactly TextBox type do you mean -- there are more than one, so please find it yourself -- this is one click away.

Solution 1

Assuming Winforms, handle the TextBox.TextChanged event:

C#

private void myTextBox_TextChanged(object sender, EventArgs e)
    {
    if (!string.IsNullOrEmpty(myTextBox.Text))
        {
        myOtherTextBox.Text = myTextBox.Text.Substring(0, 3);
        }
    }

Solution 2

C#

private void TextBox1_KeyUp(object sender, KeyEventArgs e)//Select KeyUp from Event
        {
           if(TextBox2.Text.Length<3)
            Textbox2.Text=Textbox1.Text.ToUpper; 
        }

<pre lang="c#">

{
if (txtcompanyname.Text.Length > 3)
{
txtAbbrevation.Text = txtcompanyname.Text;
}
}
</pre>
