Question

I am using C#.Net. I have textbox which allow only number, decimal and percentage(%) sign. I have the keycode for all number and decimal, but what is the ‘%’ sign’s keycode?

How can I check the keydown event for %?

Answer 1

Something like this:

private void yourControl_KeyDown(object sender, KeyEventArgs e) {    if((e.KeyCode == Keys.D5) && e.Shift)    {       // User pressed '%' ...    } } 

or

private void yourControl_KeyDown(object sender, KeyEventArgs e) {     switch(e.KeyCode)     {         //...          case Keys.D5:             if(e.Shift)             {                 // Handle '%'             }             else             {                 // Handle '5'             }             break;         // ...     } } 

You want to check that the key being pressed is the 5 key, and that it has been modified by pressing the shift key.
