  • CheckedComboBoxEdit.ItemCheck Event

    Fires after an item’s check state was changed.

    Namespace: DevExpress.XtraEditors

    Assembly: DevExpress.XtraEditors.v25.1.dll

    NuGet Package: DevExpress.Win.Navigation

    Declaration

    [DXCategory("Events")]
    public event EventHandler<ItemCheckEventArgs> ItemCheck

    Event Data

    The ItemCheck event's data class is ItemCheckEventArgs. The following properties provide information specific to this event:

    Property Description
    Index Gets the index of the item whose state was changed.
    State Gets the state of the item.

    Remarks

    The ItemCheck event fires when an item’s CheckState property is changed by the user or in code. Use the State parameter to get the new check state. The Index event parameter gets the item’s index.

    The ItemChecking event fires before the check state changes and allows you to cancel the action.

    Example

    This example demonstrates how to handle the CustomSort event to sort the checked items first and then the rest of the items.

    using DevExpress.XtraEditors.Controls;
    
    private void checkedComboBoxEdit1_CustomSort(object sender, CheckedListBoxCustomSortEventArgs e) {
        if(e.Item1.CheckState == e.Item2.CheckState)
            e.Result = ((string)e.Value1).CompareTo((string)e.Value2);
        else
            e.Result = e.Item1.CheckState == CheckState.Checked ? -1 : 1;
    }
    private void checkedComboBoxEdit1_ItemCheck(object sender, DevExpress.XtraEditors.Controls.ItemCheckEventArgs e) {
        checkedComboBoxEdit1.Sort();
    }
    private void Form1_Load(object sender, EventArgs e) {
        checkedComboBoxEdit1.Properties.Items.AddRange(
          new CheckedListBoxItem[] {
            new CheckedListBoxItem(){ Value = "Bart Arnaz" },
            new CheckedListBoxItem(){ Value = "Leah Simpson" },
            new CheckedListBoxItem(){ Value = "Arnie Schwartz" },
            new CheckedListBoxItem(){ Value = "Billy Zimmer" },
            new CheckedListBoxItem(){ Value = "Samantha Piper" },
            new CheckedListBoxItem(){ Value = "Maggie Boxter" },
            new CheckedListBoxItem(){ Value = "Brad Farkus" },
        });
    }
