	this.btnOk.DialogResult = DialogResult.OK;
	this.AcceptButton = this.btnOk;
}

private void btnOk_Click(object sender, System.EventArgs e)
{
	bool allowClose = true;

	//process the ok click

	if (!allowClose)
	{
		//clear the dialog result so it won't close
		this.DialogResult = DialogResult.None;

Remarks

The UltraButton is a standard windows button control and may be clicked using the mouse or keyboard (using the SPACE or ENTER keys).

Set the AcceptButton or CancelButton property of a Form to the button to allow the click event to be invoked using the ENTER or ESC keys respectively even if the button does not have focus.

When the form containing the UltraButton is displayed using the form's ShowDialog method, the System.Windows.Forms.DialogResult property of the button may be used to specify the return value of the ShowDialog method.

The UltraButton has much of the same functionality as the inbox Button control with some additional features including the ability to fire the click event repeatedly while the button is pressed (AutoRepeat) and the ability to be displayed with non-rectangular shapes (ShapeImage). The default appearance of the button can be modified using the ControlBase.Appearance property. The ControlBase.HotTrackAppearance can be used to adjust the appearance of the button when the mouse is positioned over the button when ControlBase.UseHotTracking is set to true. The UltraButtonBase.PressedAppearance affects the appearance of the button when the button is pressed.

Note If the control that has focus accepts and processes the ENTER or ESC key, the UltraButton will not process it.

Note If the operating system supports themes and P:Infragistics.Win.UltraControlBase.SupportThemes is true, the appearance of the control will be rendered using those these and will not use the colors specified in the associated appearance properties.
