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 e-treegrid-editsettings tag helper as Dialog.

<ejs-treegrid id="TreeGrid" dataSource="@ViewBag.datasource" height="400" childMapping="Children" treeColumnIndex="1" toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Update", "Cancel" })">
    <e-treegrid-editsettings allowAdding="true" allowEditing="true" allowDeleting="true" mode="Dialog"></e-treegrid-editsettings>
    <e-treegrid-columns>
        <e-treegrid-column field="TaskId" headerText="Task ID" isPrimaryKey="true" textAlign="Right" width="100"></e-treegrid-column>
        <e-treegrid-column field="TaskName" headerText="Task Name" editType="stringedit" width="190"></e-treegrid-column>
        <e-treegrid-column field="StartDate" headerText="Start Date" editType="datepickeredit" textAlign="Right" format="yMd" type="date" width="130"></e-treegrid-column>
        <e-treegrid-column field="Duration" headerText="Duration" editType="numericedit" textAlign="Right" width="120"></e-treegrid-column>
    </e-treegrid-columns>
</ejs-treegrid>
public IActionResult Index()
{
    var tree = TreeData.GetDefaultData();
    ViewBag.datasource = tree;
    return View();
}
