FIX. RadPanel - controls in RadPanel redraw slowly when changing the Enabled state of the panel.
Controls in RadPanel redraw slowly when changing the Enabled state of the panel.

Workaround:

private void radButton1_Click(object sender, EventArgs e)
{
    if (this.radPanel1.Enabled)
    {
        this.radPanel1.Enabled = false;
    }
    else
    {
        this.radPanel1.Visible = false;
        this.radPanel1.Enabled = true;
        this.radPanel1.Visible = true;
    }
}

Any news on this?
This slows down many of our forms considerably and looks really horrible.
This should be a high priority bug, since there is no workaround and it is also a very common usecase.
RadPageView also has the exact same problem (i guess it uses panels?)

Hello Stefan, thank you for your answer.
Unfortionatilly the workaround you provided does not help in my case.
When the control gets visible again the child controls still redraw slowly.

Please think about scheduling this for the next release, this needs to be properly fixed.

6 years old and still not fixed, please consider fixing this
This makes the RadPanel nearly unusable in these conditions because it looks really unprofessional
