2st:It can match customer input automatically!
I looked for a lot of controls and articles , but it does not suit for me ,
I have another question about datagridview!

Staffs need to input a lot of data for Daily Report,I want to do a program instead of hand-inputing!I thought it may be easy,I was wrong ,Staff have to spend too much time for inputing!Because of Inputting-Type,they input data into TextBox and then click save button,afert that they begin to another data.Now I want to change , I think ,we can input data into datagridview ,and save the data at last !It can save time , DataGridView contain a comboboxcolumn , but it is not very good !
