We can select any option in the dropdown list. Now add state = "readonly" in the Combobox object, it will make the Combobox Entry Widget disabled.
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.
Right click the Combo Box you want to disable typing, then click Properties from the right-clicking menu. See screenshot: 3. In the Properties dialog box, select 2 – fmStyleDropDownList from the Style drop-down list, and then close this dialog box.
Use the ComboStyle property:
comboBox.DropDownStyle = ComboBoxStyle.DropDownList;
This is another method I use because changing DropDownSyle to DropDownList makes it look 3D and sometimes its just plain ugly.
You can prevent user input by handling the KeyPress event of the ComboBox like this.
private void ComboBox1_KeyPress(object sender, KeyPressEventArgs e)
{
e.Handled = true;
}
Yow can change the DropDownStyle in properties to DropDownList. This will not show the TextBox for filter.
