When you add a GridViewComboBoxColumn
, it is necessary to set its DataSource
properties in order to setup it properly. Then, it is just necessary to specify the GridViewComboBoxColumn.AutoCompleteMode
property and set the DropDownStyle
property to DropDown
in order to allow suggesting the matches while typing. Nothing else will be required.
According to the provided sample code snippet, it seems that you handle the CellEditorInitialized
event and change the DisplayMember
properties. In addition, you specify the AutoCompleteDataSource
which means that this collection will be used for the auto-complete functionality. It is not clear whether you have a DataSource
applied to the GridViewComboBoxColumn
I have prepared a sample project for your reference. Please refer to the attached zip file. Could you please give it a try and get back to me with further information whether the behavior is acceptable when testing on your end. Feel free to modify the project in a way to reproduce the experienced issue and get back to me with it so I can investigate the precise case. Thank you in advance.
I am looking forward to your reply.
