  Hello Support Team,

  I am currently using ColumnValueConverter in a column, but I am experiencing an issue with auto-suggestion.

  For example, when I type “A”, the column automatically suggests “AAAAAAA”. I would like to disable this suggestion behavior so that the column only accepts the value I type without showing or applying automatic suggestions.

  Could you please guide me on how to turn off the auto-suggestion feature for a column that uses ColumnValueConverter?

  Thank you for your support.sampleWPF.zip

  Hi,

  Thank you for sharing the sample project. We investigated the scenario but could not find a direct way to disable this AutoComplete feature. We are getting in touch with the development team to see if they can suggest a possible solution. We will keep you updated as soon as we receive any further information from them.

  Hi,

  Apologies for the delay in response.

  As per the development team, there is unfortunately no direct way to disable the AutoComplete feature of the built-in C1FlexComboBox used for the ValueConverter columns.

  The only workaround is to use a custom editor (such as ComboBox or C1ComboBox) by overriding the CreateCellEditor method of the CellFactory. Please refer to the updated sample project showing a simple implementation of this approach.
