To reproduce: - When the filter is set to contains the item is different than the item is selected from the drop-down and the text is taken from the append functionality. Workaround Either change the filter to StarrtsWith or remove the suggest functionality.
Hello, Mahesh,
The purpose of the Append autocomplete mode is to autocomplete the editable part with the first item's text that matches the entered text. It is always with StartsWith logic because it appends the ending characters:
However, if you add a FilterDescriptor with FilterOperator.Contains, the AutoCompleteMode should be Suggest. Otherwise, both autocomplete modes, Append and Suggest with Contains, will be in contradiction as it is illustrated below. If you type "M", the first item is selected in the suggest popup because it contains "M". But the editable part is appended with the text from the third item which is expected for the StartsWith autocomplete mode:
As it is explained in the online documentation, the AutoFilter functionality should be used with Suggest mode: https://devdocs.telerik.com/devtools/winforms/controls/multicolumncombobox/features/auto-complete
I hope this information helps.
