Prevent users from editing text in ComboBox-DOT NET

Question

How we can prevent users of the application from editing a text in ComboBox controls in the .NET 4.0?

Answer 1

ComboBox class has DropDownStyle property that is used to describe display style of an item in a ComboBox control. DropDownStyle property allows the value from a ComboBoxStyle enumeration that contains three members to describe styles for items like: DropDownList, Simple and DropDown. DropDownList value of a ComboBoxStyle enumeration is selected to set ComboBox control as non-editable by the users, as described in the following code:

Code for C#:

ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList;

Code for VB:

ComboBox1.DropDownStyle = ComboBoxStyle.DropDownList
