Command Column Editing in ASP.NET CORE Tree Grid Component

21 Dec 20224 minutes to read

The command column provides an option to add CRUD action buttons in a column. This can be defined by the commands property of e-treegrid-column tag helper.

The available built-in command buttons are:

Command Button Actions
Edit Edit the current row.
Delete Delete the current row.
Save Update the edited row.
Cancel Cancel the edited state. 
@{ 
    List<object> commands = new List<object>();
    commands.Add(new { type = "Edit", buttonOption = new { iconCss = "e-icons e-edit", cssClass = "e-flat" } });
    commands.Add(new { type = "Delete", buttonOption = new { iconCss = "e-icons e-delete", cssClass = "e-flat" } });
    commands.Add(new { type = "Save", buttonOption = new { iconCss = "e-icons e-update", cssClass = "e-flat" } });
    commands.Add(new { type = "Cancel", buttonOption = new { iconCss = "e-icons e-cancel-icon", cssClass = "e-flat" } });
}

<ejs-treegrid id="TreeGrid" dataSource="@ViewBag.dataSource" height="400" childMapping="Children" treeColumnIndex="1">
    <e-treegrid-editsettings allowAdding="true" allowEditing="true" allowDeleting="true" mode="Row"></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="Duration" headerText="Duration" textAlign="Right" width="120"></e-treegrid-column>
        <e-treegrid-column headerText="Manage Records" width="120" commands=commands></e-treegrid-column>
    </e-treegrid-columns>
</ejs-treegrid>
public IActionResult Index()
{
    var tree = TreeData.GetDefaultData();
    ViewBag.dataSource = tree;
    return View();
}

Custom command

The custom command buttons can be added in a column by using the commands property of e-treegrid-column tag helper and the action for the custom buttons can be defined in the Click event of an Button Option.

@{
    List<object> commands = new List<object>();
    commands.Add(new { type = "taskstatus", buttonOption = new { content = "Details", cssClass = "e-flat e-details" } }); // custom
}

<script>
    function load() {
            this.columns[3].commands[0].buttonOption.click = function (args) {     //click event for custom command button
            var treegrid = document.getElementById('TreeGrid').ej2_instances[0];  // treegrid instance
            var rowObj= treegrid.grid.getRowObjectFromUID(ej.base.closest(args.target, '.e-row').getAttribute('data-uid'));
            alert(JSON.stringify(rowObj.data));  // display row data
         }
    }
</script>

<ejs-treegrid id="TreeGrid" dataSource="@ViewBag.dataSource" height="400" childMapping="Children" treeColumnIndex="1" load="load">
    <e-treegrid-editsettings allowAdding="true" allowEditing="true" allowDeleting="true" mode="Row"></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="Duration" headerText="Duration" textAlign="Right" width="120"></e-treegrid-column>
        <e-treegrid-column headerText="Manage Records" width="120" commands=commands></e-treegrid-column>
    </e-treegrid-columns>

{
    var tree = TreeData.GetDefaultData();
    ViewBag.dataSource = tree;
    return View();
}
