Dialog Editing in ASP.NET MVC Tree Grid Component

21 Dec 20221 minute to read

In Dialog edit mode, when you start editing the currently selected row, data will be shown on a dialog.
You can change the cell values and save edited data to the data source.
To enable Dialog edit, set the Mode property of EditSettings as Dialog.

@using Syncfusion.EJ2.Grids

@(Html.EJS().TreeGrid("TreeGrid").DataSource((IEnumerable<object>)ViewBag.datasource)
      .EditSettings(edit =>
       {
        edit.AllowAdding(true);
        edit.AllowDeleting(true);
        edit.AllowEditing(true);
        edit.Mode(Syncfusion.EJ2.TreeGrid.EditMode.Dialog);

       })
       .Toolbar(new List<string>() { "Add", "Edit", "Delete", "Update", "Cancel" })
       .Columns(col =>
        {
          col.Field("TaskId").HeaderText("Task ID").IsPrimaryKey(true).Width(120)
             .TextAlign(TextAlign.Right).Add();
          col.Field("TaskName").HeaderText("Task Name").Add();
          col.Field("StartDate").HeaderText("Start Date").Width(150).Format("yMd")
             .EditType("datepickeredit").TextAlign(TextAlign.Right).Add();
           col.Field("Duration").HeaderText("Duration").Width("110").EditType("numericedit")
              .Edit(new { @params = new { format = "n" } }).TextAlign(TextAlign.Right).Add();

        }).Height(400).ChildMapping("Children").TreeColumnIndex(1).Render())
public IActionResult Index()
{
    var tree = TreeData.GetDefaultData();
    ViewBag.datasource = tree;
    return View();
}
