Hi GZ,
Sorry for the long delay in getting back to you.
You can stop the AutoHideAnimationStart event getting fired by using the width and height of the panel. AnimationStart event get fired when the width and height of the panel is zero. Please refer to the code snippet given below:
private void dockingManager1_AutoHideAnimationStart(object sender, Syncfusion.Windows.Forms.Tools.AutoHideAnimationEventArgs arg)
{
if (arg.Control.Size.Width == 0 && arg.Control.Size.Height == 0)
{
Console.WriteLine("Animation Start");
}
}
Please refer to the sample given below which illustrates the above:
