Excel Export in ASP.NET MVC Gantt control

Gantt supports client-side exporting, which allows you to export its data to the Excel and CSV formats. Use the excelExport and csvExport methods for exporting. To enable Excel export in the Gantt, set the AllowExcelExport to true.

razor
excelExport.cs
@(Html.EJS().Gantt("GanttContainer").DataSource((IEnumerable<object>)ViewBag.DataSource).AllowExcelExport(true).TaskFields(ts => ts.Id(
    "TaskId").Name("TaskName").StartDate("StartDate").Duration("Duration").Progress("Progress").Child("SubTasks")).Toolbar(new List<string>() {
         "ExcelExport", "CsvExport" }).ToolbarClick("toolbarClick").Render())

<script>
    function toolbarClick(args) {
        var ganttObj = document.getElementById("GanttContainer").ej2_instances[0];
        if (args.item.id === "GanttContainer_excelexport") {
            ganttObj.excelExport();
        }
        else if (args.item.id === "GanttContainer_csvexport") {
            ganttObj.csvExport();

Multiple Gantt exporting

In Gantt, the Excel export provides support to export multiple Gantt data in new sheet or same sheet.

Same sheet

The Excel export provides support to export multiple Gantt data in the same sheet. To export in same sheet, define multipleExport.type as AppendToSheet in ExcelExportProperties. You can also provide blank rows between exported multiple Gantt data. These blank rows count can be defined using multipleExport.blankRows.

razor
sameSheet.cs
@(Html.EJS().Gantt("GanttContainer1").DataSource((IEnumerable<object>)ViewBag.FirstData).Height("280px").AllowExcelExport(true).TaskFields(ts =>

Customize the Excel export

Gantt Excel export allows the users to customize the exported document based on requirement.

Export hidden columns

In Gantt, the Excel export provides an option to export hidden columns by defining includeHiddenColumn as true.

razor

Show or hide columns on exported Excel

In Gantt, while exporting, you can show a hidden column or hide a visible column using the ToolbarClick and ExcelExportComplete events.

In the ToolbarClick event, using the args.item.id property, you can show or hide columns by setting the Columns.Visible property to true or false respectively.

Similarly, in the excelExportComplete event, you can revert the columns visibility back to the previous state.

razor
showHideColumn.cs

Cell formatting during export

In Gantt, you can customize the TreeGrid cells in the exported document using the ExcelQueryCellInfo event. In this event, you can format the TreeGrid cells of exported Excel and CSV documents based on the required condition.

In the following sample, the background color has been customized for TaskId column in the exported Excel using the args.style and backColor properties.

razor
cellFormat.cs
@(Html.EJS().Gantt("GanttContainer").DataSource((IEnumerable<object>)ViewBag.DataSource).AllowExcelExport(true).TaskFields(ts => ts.Id(
    "TaskId").Name("TaskName").StartDate("StartDate").Duration("Duration").Progress("Progress").Child("SubTasks")).Toolbar(new List<string>() {
         "ExcelExport" }).Columns(col =>
                {
                    col.Field("TaskId").Width(100).HeaderText("Task ID").Visible(false).Add();
                    col.Field("TaskName").HeaderText("Task Name").Width(150).Add();

Theme

The Excel export also provides an option to include custom theme for exported Excel document.

To apply theme in exported Excel, define the theme in ExcelExportProperties.

razor

By default, material theme is applied to the exported Excel document.

The Excel export also allows users to include header and footer contents to the exported Excel document.
