I used your code and that solved my problem. Great work !!!

Thanks again.

Initially, I extended standard RadioButton in order ust to change its default appearance without controlling the auto size because the base class OnPaint will change all my estimations if AutoSize mode is on. That is why it works only in non AutoSize mode.

I can offer you a simple work around that is not very elegant but it may help you to use the control in AutoSize mode.

You need to override AutoSize property in order to suspend original RadioButton logic when custom appearance is activated and to allow original logic when custom appearance is not activated.

private bool _customAutoSize = false;
public override bool AutoSize
{
get
{
if (!_enableCustomUIAppearance)
{
return base.AutoSize;
}
return _customAutoSize;
}
set
{
if (!_enableCustomUIAppearance)
{
base.AutoSize = value;
}
else if (_customAutoSize != value)
{
_customAutoSize = value;
Invalidate();
}
}
}

Than you can simply extend the OnPaint method adding the code below before calculate offset comment.

if (_customAutoSize)
{
Width = (int)((stringMeasure.Width + Padding.Left + Padding.Right + offset + distance + radioButtonWidthHeight) + 0.5);
Height = (int)((stringMeasure.Height + Padding.Top + Padding.Bottom + offset) + 0.5);
}

Then remove the else statement of calculate offsets and you also should remove OnAutoSizeChanged. Please remove setting of AutoSize in EnableCustomUIAppearance property.

First of all thanks for your nice work. I appreciate your work.

Now, I found one problem while using radiobutton code. Description is given bellow.

In AutoSize = true mode if you assign radiobutton’s Text property to more then 60 characters string. Text is trimmed from right side. Please guide me how to solve this problem ?

To replicate this problem just do some change in above code..
protected override void OnAutoSizeChanged(EventArgs e)
{
if (_enableCustomUIAppearance)
{
////Set AutoSize to false.
//if (AutoSize)
//{
// AutoSize = false;
//}
}
base.OnAutoSizeChanged(e);
}
After this just build dll and use it in application. You can see the problem.

Control is working fine when text is less then 55 characters. I particularly want to set AutoSize = true because in my application i want to generate controls at runtime.

Thanks.
