不允许用户在组合框（而不是数据绑定列表）中输入值

Question

i have a combobox in the form which is bounded with database .

i am trying to solve two issues .

1. not to let user to enter the values that are not in data list .

2. not to run code until the full value is entered .

for eg. when i enter the first letter of any value and press enter ,code is running with the values that first matched the entered word . like for 'd' code is running with no 'd001'

requirement is that , no execution until the user enter or select the full value .

thanks in advance and sorry for any English related error .

Answer 1

Try below from code

comboBox1.DropDownStyle = ComboBoxStyle.DropDownList;

You can also set the DropDownStyle to DropDownList from Properties window of the combobox.
