RadCheckbox focus border

[Bao]

HI,

I have a problem when i focus. If i tab to checkbox it has the border highlight around the text . It is fine. But when i set it focused when open form. It does not display border like when i tab to radcheckbox. How can i display the focused border when open form ???

 

Thanks.

Hi Bao,

This is controlled by the .NET framework and there is no way to manually show this border. You can check this with the standard checkbox as well. What you can do is manually change the border when the control gains or loses the focus:

public RadForm1()
{
    InitializeComponent();

    radCheckBox1.GotFocus += RadCheckBox1_GotFocus;
    radCheckBox1.LostFocus += RadCheckBox1_LostFocus;
}

private void RadCheckBox1_LostFocus(object sender, EventArgs e)
{
    radCheckBox1.ButtonElement.BorderElement.ShouldPaint = false;
}

private void RadCheckBox1_GotFocus(object sender, EventArgs e)
{

    radCheckBox1.ButtonElement.BorderElement.ShouldPaint = true;
    radCheckBox1.ButtonElement.BorderElement.ForeColor = Color.Red;
    radCheckBox1.ButtonElement.BorderElement.Width = 2;
}

I hope this will be useful. Let me know if you have additional questions.

Hello Bao,

Yes, the focus border is controlled by the OS and cannot be shown with code. 

Should you have any other questions do not hesitate to ask.
