When you convert it copy the result to your code to avoid using image file

Really really cool. Can I also add the same button to my canvas? if possible can you share the code? currently, I am learning c# and find this UI modification thing really cool so I wanted to learn this and want to add one extra button that zoom selected geometry button beside the solver.

I don’t Know if there is zoom selected geometry in Grasshopper SDK.
Maybe we need first find selected geometries and use their ids to zoom selected in Rhino.
If i find a way i will add it as a button, and sorry i can’t share c# code, python code is enough you can use it.

After researching your famous solution on the loading process, I found the GH_AssemblyPriority class:

And indeed, it is really simpler.

if (addBtns)
{
  var button = new ToolStripButton("InvertSelect", Bitmap.FromFile(icons[1]), (sender, e) => Instances.ActiveCanvas.Document.InvertSelection(),"InvertSelect");  // this is your code but I changed on function, because I am exproling sometings.
  button.Name = "InvertSelect";
  button.CheckOnClick = false;
  button.Checked = true;
  button.DisplayStyle = ToolStripItemDisplayStyle.Image;
  toolbar.Items.Add(button);
}

if (removeBtns)
{
  var buttons = new List<ToolStripItem>();
  foreach (ToolStripItem item in toolbar.Items)
    if (item.Name == "InvertSelect")
      buttons.Add(item);
  foreach (var btn in buttons)
    toolbar.Items.Remove(btn);
}

hello sir, @Mahdiyar really cool code really liked it

I just modify it with a

GH_Document.InvertSelection Method

but i am having a problem adding

GH_Document.Enabled Property

and

GH_Document.EnableSolutions Property

these two properly in the code.

actually, I am new to learning C# so I am not able to add this.

Because of this code I learn how to assign methods in code but did not have an idea of how to add and modify properties.

if possible can you guide me with this ??

Thank you
