Auto Complete Support in WPF ComboBox

You can find and select matching items from the drop-down list of the ComboBoxAdv control by using the AutoCompleteMode property. It can be used for both single and multiple selections in editable mode.

There are two different AutoCompleteMode values.

  • None – No suggestion is made. This is the default value.
  • Suggest – Suggestions are displayed in a drop-down menu based on the typed text.

Suggest

By setting the AutoCompleteMode property to Suggest, a list of possible matches is suggested and displayed in the drop-down list. The search text is included at the start of the suggested items.

<syncfusion:ComboBoxAdv AutoCompleteMode="Suggest"/>
ComboBoxAdv comboBox = new ComboBoxAdv();       
combobox.AutoCompleteMode = AutoCompleModes.Suggest;

NOTE

Suggest mode applies only when the ComboBoxAdv control is populated with an ItemsSource collection. When AutoCompleteMode is set to Suggest and IsTextSearchEnabled is set to True in editable mode, AutoCompleteMode takes precedence.
