CheckEdit() Constructor

Initializes a new CheckEdit control instance with default settings.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v23.2.dll

NuGet Package: DevExpress.Win.Navigation


public CheckEdit()


Use this constructor to create a new instance of the CheckEdit control at runtime. The constructor initializes the new check editor with default settings.

You can use methods and properties of the new check editor to adjust it as required: you can specify its name, caption text, check box style, look and feel, etc. The new editor needs to be added to the parent container’s Controls collection in order to be displayed on the form.

To create a check editor in-place for the XtraGrid, for instance, you should create a corresponding repository item of the RepositoryItemCheckEdit class and assign it to a column.


This example demonstrates how to programmatically create two check editors, initialize their properties and assign the same handler for their CheckEdit.CheckedChanged events. The created check editors will be used to control the visibility and availability of a standard button control. The example implies that the button is already placed onto a form.

Changing the check state of the first check editor affects both the button’s visibility and the second check editor’s availability. The second check editor specifies the availability of the button for end-users.

The image below displays the example application.


using DevExpress.XtraEditors;
using DevExpress.Utils;

private void CreateCheckEditors() {
    // creating and initializing the first check editor
    CheckEdit chEdit1 = new CheckEdit();
    chEdit1.Properties.Caption = "Hide Button";
    chEdit1.Name = "chEdit1";
    chEdit1.Location = new System.Drawing.Point(6, 35);
    chEdit1.Width = 100;
    // setting the editor's check state depending upon the button's visibility
    if (!(button1.Visible)) chEdit1.Checked = true;
    // assigning a handler for the CheckChanged event of the first check editor
    chEdit1.CheckedChanged += new EventHandler(CheckedChanged);

    // creating and initializing the second check editor
    CheckEdit chEdit2 = new CheckEdit();
    chEdit2.Properties.Caption = "Disable Button";
    chEdit2.Name = "chEdit2";
    chEdit2.Location = new System.Drawing.Point(6, 55);
    chEdit2.Width = 100;
    // setting the editor's check state depending upon the button's availability
    if (!(button1.Enabled)) chEdit2.Checked = true;
    if (!(button1.Visible)) chEdit2.Enabled = false;
    // assigning a handler for the CheckChanged event of the second check editor
    chEdit2.CheckedChanged += new EventHandler(CheckedChanged);

private void CheckedChanged(object sender, System.EventArgs e) {
    CheckEdit edit = sender as CheckEdit;
    switch (edit.Checked) {
        case true:
            if (edit == GetCheckEdit("chEdit1")){
                // hiding the button
                button1.Visible = false;
                // disabling the second check editor
                GetCheckEdit("chEdit2").Enabled = false;
            else if (edit == GetCheckEdit("chEdit2")){
                // enabling the button
                button1.Enabled = false;
        case false:
            if (edit == GetCheckEdit("chEdit1")){
                // showing the button
                button1.Visible = true;
                // enabling the second check editor
                GetCheckEdit("chEdit2").Enabled = true;
            else if (edit == GetCheckEdit("chEdit2")){
                // disabling the button
                button1.Enabled = true;

private CheckEdit GetCheckEdit(string editName){
    foreach(Control control in this.Controls){
        if ((control is CheckEdit) && (control.Name == editName)) 
            return control as CheckEdit;
    return null;
