I have a simple form, in which the first two controls are radio buttons. I dont' want either radio button checked, but no matter what I do, the first radio button is always checked when I run the form. I want the user to have to pick one of the radio buttons, and if they don't we have code that warns a one of the radio buttons must be picked. Witht hat said, I am kind of stuck, as I played with setting them both to IsChecked = false and CheckState = CheckState.UnChecked, but the first RadioButton, at runtime, gets checked anyway.
Also, I don't want the radio button to auto check when the user uses the ARROW keys to switch between them. I want the user to have to either click the SPACE BAR or click with the mouse, is this possible.
TIA

Hi, Mark,
Following the provided information, I have created a brand new project and added two RadRadioButton controls on the form. Indeed, when I run the application, the first RadRadioButton is toggled even though I set explicitly its ToggleState property to Off. This is observed if only these two controls are on the form or one of the RadRadioButtons is the active control when the application starts. If you focus another control, e.g. RadTextBox when the application starts, none of the radio buttons is checked.
The possible solution that i can suggest is to handle the form's Shown event and un-toggle the radio button:
private void RadForm1_Shown(object sender, EventArgs e)
{
this.radRadioButton1.ToggleState = Telerik.WinControls.Enumerations.ToggleState.Off;
}I hope this information helps. If you need any further assistance please don't hesitate to contact me.
