CheckEdit.CheckedChanged Event

Fires after the CheckEdit.Checked property value has been changed.

Namespace: DevExpress.XtraEditors

Assembly: DevExpress.XtraEditors.v19.1.dll

Declaration

C#

[DXCategory("Events")]
public event EventHandler CheckedChanged

VB.NET

<DXCategory("Events")>
Public Event CheckedChanged As EventHandler

Event Data

The CheckedChanged event's data class is EventArgs.

Remarks

The editor’s CheckedChanged event is the equivalent of the RepositoryItemCheckEdit.CheckedChanged event available from the CheckEdit.Properties object. When you add/remove an event handler for the current event, you actually affect the RepositoryItemCheckEdit.CheckedChanged event.

The code sample below allows you to determine if the checked state changed programmatically, or if a user changed it manually.

C#

checkEdit1.Click += checkEdit1_Click;
checkEdit1.CheckedChanged += checkEdit1_CheckedChanged;
bool IsClick = false;
private void checkEdit1_Click(object sender, EventArgs e)
{
    IsClick = true;
}private void checkEdit1_CheckedChanged(object sender, EventArgs e)
{
    if (IsClick)
    {
        // a user has clicked the CheckEdit
        // react to user's action
        IsClick = false;
    }
}

VB.NET

Private checkEdit1.Click += AddressOf checkEdit1_Click
Private checkEdit1.CheckedChanged += AddressOf checkEdit1_CheckedChanged
Private IsClick As Boolean = False
Private Sub checkEdit1_Click(ByVal sender As Object, ByVal e As EventArgs)
    IsClick = True
End Sub
Private Sub checkEdit1_CheckedChanged(ByVal sender As Object, ByVal e As EventArgs)
    If IsClick Then
      ' a user has clicked the CheckEdit
      ' react to user's action
      IsClick = False
    End If
End Sub
