c# combo box winform

Question

I have a combobox with the text 'select'. I want to set it so that the user cannot type over that. Currently they are able to. I cannot see any read only option for this though.

Can any body advise.

Thanks.

Answer 2

尝试设置DropDownStyle = ComboBoxStyle.DropDownList

Answer 3

If you want it for all items then

 set the ComboBox's DropDownStyle property to DropDownList. 

If you want it for the 'Select' item alone then handle KeyDown of ComboBox PS: I've --Select-- as the first item in ComboBox

 private void comboBox1_KeyDown(object sender, KeyEventArgs e)
        {
            if (comboBox1.SelectedIndex == 0)
            {

                e.SuppressKeyPress = true;
            }
        }

Answer 4

Use DropDownStyle = DropDownList. Hope that helps.

Answer 5

This works

private void ComboBox_KeyPress(object sender, KeyPressEventArgs e)
    {
        e.Handled = true;
    }
