TAB KEY working together KEY PRESS event

thomaz · #1 (**permalink**) September 30th, 2003, 09:56 AM

I use the Keypress event to verify when the user typing the ENTER KEY, like below:

if (e.KeyChar == 13){//using the ASCII code of a ENTER KEY
    if (this.cboSiglacolecao.SelectedIndex > 0){

    this.siglaColecao = "";
        this.cboSiglacolecao.DroppedDown = false;
        {
}

But now i need to verify when the user typing the EMTER KEY and the TAB KEY.
The ASCII code of the TAB KEY is (11 - Vertical Tabulator and 9 - Horizontal Tabulator) but when i use them the code does not function, like below:

if (e.KeyChar == 13 || e.KeyChar == 9){//using the ASCII code of a ENTER KEY and TAB KEY
    if (this.cboSiglacolecao.SelectedIndex > 0){

    this.siglaColecao = "";
        this.cboSiglacolecao.DroppedDown = false;
        {
}

How can i execute the code when the user pressures the TAB KEY?
OR
How can i capture the ASCII code of the TAB KEY?

Hi Thomaz,

You can check for \t (tab) and \r (enter) instead of numeric values. This:

Code:

if (e.KeyChar == '\t' || e.KeyChar == '\r')
{
    MessageBox.Show("Tab or Enter pressed");
}

should do the trick.

Cheers,

Imar

hi, I´m having a big problem, well I´m porgraming with c#.net 2005, and I´d like to make a validation.
I have 2 textbox, in the first one I only want numbers and ",".
In the second textbox I only want letters.
I was trying it with visual basic .net 2005 with ascii code. But now I want to do it with c#.net 2005.

jammer,
For windows application, check the Char structure in C#. For web application do some client side code.
