CheckedItems Property

Returns a collection which contains the members of the Items collection whose CheckState property returns 'Checked'.
Syntax
'Declaration
 
Public ReadOnly Property CheckedItems As Infragistics.Win.CheckedValueListItemsCollection
public Infragistics.Win.CheckedValueListItemsCollection CheckedItems {get;}
Remarks

The CheckedItems collection property mirrors the property of the same name that is exposed by the ValueList class.

The CheckedItems collection is similar to the collection of the same name exposed by the .NET CheckedListBox control. In situations where an application requires that the end user be able to select multiple values from a dropdown, checkboxes can be used to accomplish this; rather than the value being determined by the one selected item, it can be determined instead by the members of the CheckedItems collection.

Example
The following code sample demonstrates how to use the CheckedItems collection to determine whether an item with a particular value is checked:

Imports Infragistics.Win
Imports Infragistics.Win.UltraWinEditors
Imports System.Diagnostics

	Public Function IsItemChecked(ByVal comboEditor As UltraComboEditor, ByVal dataValue As Object) As Boolean

        Dim checkedItems As CheckedValueListItemsCollection = comboEditor.CheckedItems

        '  Iterate the CheckedItems collection and compare the value
        '  of each item therein to the specified value.
        Dim item As ValueListItem
        For Each item In checkedItems

            If Object.Equals(dataValue, item.DataValue) Then Return True
        Next

        Return False

	End Function
using Infragistics.Win;
using Infragistics.Win.UltraWinEditors;
using System.Diagnostics;

public bool IsItemChecked( UltraComboEditor comboEditor, object dataValue )
{
    CheckedValueListItemsCollection checkedItems = comboEditor.CheckedItems;

    //  Iterate the CheckedItems collection and compare the value
    //  of each item therein to the specified value.
    foreach( ValueListItem item in checkedItems )
    {
        if ( object.Equals(dataValue, item.DataValue) )
            return true;
    }

    return false;
}
