In Kendo Grid it is possible to show/hide buttons in command column conditionally.

How can I achieve that in TreeList?


command: [
	{
		imageClass: "k-i-info",
		name: "details",
		text: "Details",

		visible: function (dataItem) { return dataItem.LastName.charAt(0) !== "D" }

	}
]

Hi, Jaanus,

The TreeList widget doesn't have the command visibility functionality built-in, however you can achieve it by utilizing the dataBound event:

        dataBound: function() {
          let treelist = this;
          let data = treelist.dataSource.data();
          
          data.forEach(function(x, i) {
            if(x.LastName.charAt(0) !== "D") {
              let row = treelist.element.find("[data-uid='"+x.uid+"']");
              row.find("[data-command='details']").hide();
            }
          });
        }
