How to install combobox for reading or the user cannot write in the combo box, only can select data?

Question

I'm having a problem setting the combo property, so that only the user can select the values ​​that form the data, but I cannot write to the combo box.

How can I do this in C #?

Answer 1

Just change DropDownStyle to DropDownList . Or, if you want it to be fully readable, you can set Enabled = false , or if you don't like the look, I sometimes have two controls: one read-only text field and one combo box, and then hide the combo and show the text box if it should be completely readonly and vice versa.

Answer 2

I think you want to change the "DropDownStyle" parameter to "DropDownList".

Answer 3

In the keypress event handler:

 e.Handled = true; 

Answer 4

Make DropDownStyle in DropDownList

 stateComboBox.DropDownStyle = ComboBoxStyle.DropDownList; 

Answer 5

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

Answer 6

Try the following:

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