21 Dec 20223 minutes to read

The excel export allows exporting TreeGrid data to Excel document. You need to use the excelExport method for exporting. To enable Excel export in the treegrid, set the allowExcelExport as true.

<ejs-treegrid id="TreeGrid" dataSource="@ViewBag.datasource" height="220" childMapping="Children" treeColumnIndex="1" toolbar="@(new List<string>() { "ExcelExport"})" allowExcelExport="true" allowPaging="true" toolbarClick="toolbarClick">
    <e-treegrid-pagesettings pageSize="7"></e-treegrid-pagesettings>
    <e-treegrid-columns>
        <e-treegrid-column field="TaskId" headerText="Task ID" textAlign="Right" width="90"></e-treegrid-column>
        <e-treegrid-column field="TaskName" headerText="Task Name" width="180"></e-treegrid-column>
        <e-treegrid-column field="StartDate" headerText="Start Date" textAlign="Right" format="yMd" type="date" width="90"></e-treegrid-column>
        <e-treegrid-column field="Duration" headerText="Duration" textAlign="Right" width="80"></e-treegrid-column>
    </e-treegrid-columns>
</ejs-treegrid>

<script>
    function toolbarClick(args) {
        if (args['item'].text === 'Excel Export') {
            var treegrid = document.getElementById("TreeGrid").ej2_instances[0];
            treegrid.excelExport();
        }
    }
</script>
public IActionResult Index()
{
    var tree = TreeData.GetDefaultData();
    ViewBag.datasource = tree;
    return View();
}

Persist collapsed state

You can persist the collapsed state in the exported document by defining isCollapsedStatePersist property as true in TreeGridExcelExportProperties parameter of excelExport method.

<ejs-treegrid id="TreeGrid" dataSource="@ViewBag.datasource" height="220" childMapping="Children" treeColumnIndex="1" toolbar="@(new List<string>() { "ExcelExport"})" allowExcelExport="true" allowPaging="true" toolbarClick="toolbarClick">
    <e-treegrid-pagesettings pageSize="7"></e-treegrid-pagesettings>
    <e-treegrid-columns>
        <e-treegrid-column field="TaskId" headerText="Task ID" textAlign="Right" width="90"></e-treegrid-column>
        <e-treegrid-column field="TaskName" headerText="Task Name" width="180"></e-treegrid-column>
        <e-treegrid-column field="StartDate" headerText="Start Date" textAlign="Right" format="yMd" type="date" width="90"></e-treegrid-column>
        <e-treegrid-column field="Duration" headerText="Duration" textAlign="Right" width="80"></e-treegrid-column>
    </e-treegrid-columns>
</ejs-treegrid>

<script>
    function toolbarClick(args) {
        if (args['item'].text === 'Excel Export') {
            var excelExportProperties = {
              isCollapsedStatePersist: true
            };
            var treegrid = document.getElementById("TreeGrid").ej2_instances[0];
            treegrid.excelExport(excelExportProperties);
        }
    }
</script>
public IActionResult Index()
{
    var tree = TreeData.GetDefaultData();
    ViewBag.datasource = tree;
    return View();
}
