Why Choose MultiSelect for Your WinForms Applications?

Effortless Selection of Multiple Items

MultiSelect provides an effortless approach when selecting multiple items from a WinForms list. Text input with autocomplete and a drop-down of options simplify the option-picking process for end-users.

Flexible, Smart Header Gives You Options

MultiSelect has a smart header that can display items as separate tags, plain text, or summarize the count when too many items are selected.

A WinForms Tag Editor for Editing Labels

MultiSelect controls provide WinForms tag editing and label editing functionality. A bound data source is not required.

Format the Header

The MultiSelect control has a customizable header that can display selected items either as text or as tags.

  • Specify the separator character and enable wrapping
  • Configure the header to summarize the selected items once they go beyond a specified limit
  • Set the format string to show the item count
  • Specify placeholder text for when nothing is selected

Edit Mode with Autocomplete

MultiSelect supports text input, allowing the user to quickly and easily edit a list of labels or tags.

  • Use the C1MultiSelect control for tag editing with a drop-down list
  • Use the C1TagEditor control just to get the text box element
  • Tags can be further edited by double-clicking, or quickly deleted by clicking the X
  • Both support autocomplete and autosuggestion settings

Multiple Data Bindings

MultiSelect can be bound to two different data sources.

  • The DataSource is used to fill the list of all available items that are shown in the drop-down checklist
  • The TagsDataSource can be used to propagate end-user selection to some other data source, probably with different data structures than the DataSource
  • You can access selected items from the control to be used as a data source for any other control

Extended Selection Modes

MultiSelect allows you to select specific items (or all items) from a defined list. Control the selection mode (single, multiple, extended) to define how items in the list can be selected. Optionally, show or hide the checkboxes.

CheckList Component

The C1MultiSelect control uses a separate C1CheckList component to display in the drop-down. Use this component separately to provide a checklist for a multiple item selection without the header or drop-down components. The C1CheckList enables you to highlight your selection as a checklist or a simple list of items.
