Selection Mode Support in WPF AutoComplete (Classic)
5 May 20211 minute to read
AutoComplete supports two kinds of Selection Mode namely Single and Multiple. You can select the Mode using the SelectionMode property.
When the SelectionMode property is set as Single, only one item can be selected at a time. The following image illustrates the Single selection mode.
SelectionMode-Single
When the SelectionMode is set as Multiple, you can select multiple items by using the SeparatorChar property to separate the selected items. By default the SeparatorChar is “;”. This allows you to select multiple items by using the SelectionMode property. Once an item is selected the SeparatorChar is to be entered in the text box to select the next item.
The following image illustrates the Multiple selection mode.
SelectionMode—Multiple
When the SelectionMode is set as Extended, you can select multiple items at a time by pressing the Ctrl key. While selecting the multiple items, the selected items will be separated by the SeparatorChar automatically.
