[blackholeearth]

    var ktgv1 = new KryptonTreeGridView();
    ktgv1.Dock = dock.Fill;
    this.Controls.Add(ktgv1);

    // Example of adding nodes
    // Define columns
    ktgv1.Columns.Add(new KryptonTreeGridColumn { HeaderText = "name", DataPropertyName = "Column1" });
    ktgv1.Columns.Add(new KryptonTreeGridColumn { HeaderText = "age", DataPropertyName = "Column2" });
    ktgv1.Columns.Add(new KryptonTreeGridColumn { HeaderText = "birthdate", DataPropertyName = "Column3" });
    ktgv1.Columns.Add(new KryptonTreeGridColumn { HeaderText = "job", DataPropertyName = "Column4" });

    var rootNode = ktgv1.GridNodes.Add("Root", "" , "" ,"");
    var childNode1 = rootNode.Nodes.Add("jane doe", "18", "2022-12-12", "engineer");
    var childNode2 = rootNode.Nodes.Add("joe doe", "18", "2022-12-12", "engineer");
    childNode1.Nodes.Add("ch-joe doe", "18", "2022-12-12", "engineer");
    for (int i = 0; i < 500; i++)
    {
        var childNodex = rootNode.Nodes.Add($"ch-joe doe {i}", "18", "2022-12-12", "engineer");
        for (int j = 0; j < 250; j++)
        {
            childNodex.Nodes.Add($"ccx - joe doe {i}", "18", "2022-12-12", "intern");
        }

i think i found it. - add to #FAQ please.

when i type .KryptonTreeGrid crtrl space.. nothing shows in the autocomplete . i found it by mistake..

  // Example of adding nodes
  // Define columns

  //this will show expand/button
  ktgv1.Columns.Add(new KryptonTreeGridColumn { HeaderText = "name", DataPropertyName = "Column1" });  

 //normal column
  ktgv1.Columns.Add(new KryptonDataGridViewTextBoxColumn { HeaderText = "age", DataPropertyName = "Column2" });  
  ktgv1.Columns.Add(new KryptonDataGridViewTextBoxColumn { HeaderText = "birthdate", DataPropertyName = "Column3" }); 
  ktgv1.Columns.Add(new KryptonDataGridViewTextBoxColumn { HeaderText = "job", DataPropertyName = "Column4" });
