How do I set combobox read-only or user cannot write in a combo box only can select the given items? [duplicate]

Answer 1

In the keypress event handler:

e.Handled = true;

Answer 2

I think you want to change the setting called "DropDownStyle" to be "DropDownList".

Answer 3

Just change the DropDownStyle to DropDownList. Or if you want it completely read only you can set Enabled = false, or if you don't like the look of that I sometimes have two controls, one readonly textbox and one combobox and then hide the combo and show the textbox if it should be completely readonly and vice versa.

Answer 4

Try this:

    private void comboBox1_KeyDown(object sender, KeyEventArgs e)
    {
        // comboBox1 is readonly
        e.SuppressKeyPress = true;
    }

Answer 5

The solution is to change the DropDownStyle property to DropDownList. It will help.

Answer 6

Make the DropDownStyle to DropDownList

stateComboBox.DropDownStyle = ComboBoxStyle.DropDownList;
