Uppercase in Combobox text

[Lakshmi]

Hi,

How can I make the combo box text uppercase? For instance when the user
types in letters in the combobox, I want them to appear as upper case.

Thanks.

You could trap them manually in the textchanged event (bearing in mind
that the text might have changed because an item was selected).

Use the following code in the keypress event of the combo box to convert the
letters to upper case:

string str = e.KeyChar.ToStr ing().ToUpper() ;
char[] ch = str.ToCharArray ();
e.KeyChar = ch[0];

Laskhmi,

This you can do in the same way as the thousands of numeric textboxes and
autocompletebox es samples are done on internet.

Be aware not to use the keypress but the keyup event. The later gives
information about the key that has been pressed.

For the rest it is just MyPressedcharst ring.ToUpper

I hope this helps,

Cor

Re: Uppercase in Combobox text

Do you want the items in the list to also be uppercase? If so, a simple
override will do the trick:

class UppercaseComboB ox : ComboBox
{
private const int CBS_UPPERCASE = 0x2000;
protected override CreateParams CreateParams
{
get
{
CreateParams p = base.CreatePara ms;
p.Style |= CBS_UPPERCASE;
return p;
}
}
}

I try this and good

private void cboOperationCod e_KeyPress(obje ct sender, KeyPressEventAr gs e)
{
if (e.KeyChar >= 'a' && e.KeyChar <= 'z')
e.KeyChar = Convert.ToChar( e.KeyChar.ToStr ing().ToUpper() );
}
