How can I do so in C#?

C# Solutions

Solution 1 - C#

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.

Solution 2 - C#

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

Solution 3 - C#

In the keypress event handler:

e.Handled = true;

Solution 4 - C#

Make the DropDownStyle to DropDownList

stateComboBox.DropDownStyle = ComboBoxStyle.DropDownList;

Solution 5 - C#

Try this:

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

Solution 6 - C#

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