c# - Convert Text to Uppercase while typing in Text box

I am new in Visual Studio and using visual Studio 2008. In a project I want to make all text in uppercase while typed by the user without pressing shift key or caps lock on. I have used this code

TextBox1.Text = TextBox1.Text.ToUpper();

but it capitalize characters after pressing Enter key.

I just want that characters appear in uppercase while typing by the user without pressing shift key or without caps lock on.

Total page code is as...

public partial class Test : System.Web.UI.Page 
 {
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void TextBox1_TextChanged(object sender, EventArgs e)
    {
        TextBox1.Text = TextBox1.Text.ToUpper();

    }
}

Have any one any solution, please guide me.

There is a specific property for this. It is called CharacterCasing and you could set it to Upper

  TextBox1.CharacterCasing = CharacterCasing.Upper;

In ASP.NET you could try to add this to your textbox style

  style="text-transform:uppercase;"

You could find an example here: http://www.w3schools.com/cssref/pr_text_text-transform.asp
