How to customize the column properties in Treegrid

Platform: ASP.NET MVC |
Control: TreeGrid |
Published Date: July 31, 2017 |
Last Revised Date: May 29, 2019

In TreeGrid, we can dynamically update all the inner properties available in column property. And, we can include/exclude the TreeGrid columns dynamically by using “setModel” method.

Please find the code example to modify “headerText” and “textAlign” column property.

<button onclick="clickme()" style="margin-bottom:10px">Update Column</button>
          .Columns(co =>
                  co.Field("taskID").HeaderText("Task Id").Width(60).Add();
                  co.Field("taskName").HeaderText("Task Name").Add();
                  co.Field("startDate").HeaderText("Start Date").TextAlign(TextAlign.Center).Add();           
    <script type="text/javascript">
        //To dynamically change the TreeGrid columns
        function clickme() {         
            var treeObj = $("#TreeGridContainer").data("ejTreeGrid"),
                 clonedColumns = $.extend([], treeObj.model.columns),
                 duration = { field: "duration", headerText: "Duration", duration: "numericedit" };
            clonedColumns[0].headerText = "Id";
            clonedColumns[1].headerText = "Name";
            clonedColumns[3].headerText = "Percent Done";
            clonedColumns[2].textAlign = ej.TextAlign.Right;
            clonedColumns[3].textAlign = ej.TextAlign.Center;
            //To include new column dynamically
            treeObj.setModel({ "columns": clonedColumns });

 The following output is displayed as a result of the above code example.
