ThreeState Property (UltraCheckEditor)

Controls whether or not the user can select the indeterminate state of the checkbox.

Syntax

Visual Basic

'Declaration
 
Public Property ThreeState As Boolean

public bool ThreeState {get; set;}

Example

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    Me.UltraCheckEditor1.ThreeState = True
    Me.UltraCheckEditor1.CheckState = CheckState.Indeterminate
    Me.UltraCheckEditor1.IndeterminateAppearance.ForeColor = Color.Gray
    Me.UltraCheckEditor1.CheckedAppearance.ForeColor = Color.White

End Sub

C#

private void Form1_Load(object sender, System.EventArgs e)
{

	this.ultraCheckEditor1.ThreeState = true;
	this.ultraCheckEditor1.CheckState = CheckState.Indeterminate;
	this.ultraCheckEditor1.IndeterminateAppearance.ForeColor = Color.Gray;
	this.ultraCheckEditor1.CheckedAppearance.ForeColor = Color.White;

}
