CollapsibleButton

[J-S]

Hi, Is it possible to not expand the panel when I create it at runtime ?  If I set the property "isExpanded" to false after adding to my controls (me.controls.add(collapsiblepanel)) I see the panel closing when the form is loading....

Thanks !

Hello,

Thank you for writing.

Currently, there are two ways to do this:

1. In the constructor of the form set the IsExpanded property to true as you first load the ElementTree:

   RadCollapsiblePanel collapsiblePanel;
   public Form1()
   {
       InitializeComponent();
   
       collapsiblePanel = new RadCollapsiblePanel();
       this.Controls.Add(collapsiblePanel);
   
       collapsiblePanel.LoadElementTree();
       collapsiblePanel.IsExpanded = false;
   }

2. The second way to do this is when the form loads to disable the animations, collapse the panel and re-enable the animation:

   RadCollapsiblePanel collapsiblePanel;
   public Form1()
   {
       InitializeComponent();
   
       collapsiblePanel = new RadCollapsiblePanel();
       this.Controls.Add(collapsiblePanel);
   }
   
   protected override void OnLoad(EventArgs e)
   {
       base.OnLoad(e);
   
       this.collapsiblePanel.EnableAnimation = false;
       this.collapsiblePanel.Collapse();
       this.collapsiblePanel.EnableAnimation = true;
   }

Do not hesitate to write back, should you have further questions.
