TAB KEY working together KEY PRESS event
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

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