I have managed to work around this, though it is painful to need to do this. I extended the stock RadCheckBox and RadCheckBoxAccessibleObject classes to conform to what I believe is the correct behavior for these accessibility attributes. To fix the theme of the checkbox, I return the default theme for RadCheckBox. If there is a better way to accomplish this, please let me know.
public class CustomRadCheckBox : RadCheckBox
{
protected override AccessibleObject CreateAccessibilityInstance()
{
return new CustomRadCheckBoxAccessibleObject(this);
}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
public override string ThemeClassName
{
//fixes the theme
get { return "Telerik.WinControls.UI.RadCheckBox"; }
set { }
}
}
public class CustomRadCheckBoxAccessibleObject : RadCheckBoxAccessibleObject
{
public CustomRadCheckBoxAccessibleObject(RadCheckBox owner) : base(owner) { }
public override string Name
{
//if not done, the LegacyIAccessible.Name will show as the name of the button
get { return Owner.AccessibleName; }
set { }
}
public override string Description
{
//if not done, the LegacyIAccessible.Description will shows as the text of the button
get { return Owner.AccessibleDescription; }
}
}
