Namespace: DevExpress.Blazor

Assembly: DevExpress.Blazor.v25.1.dll

NuGet Package: DevExpress.Blazor

Declaration

[DefaultValue(false)]
public bool SuppressMaxRowCountError { get; set; }

Property Value

Type	Default	Description
Boolean	false	true, to suppress the exception and export the maximum available number of rows; false, to cancel the export and throw the exception.

Remarks

The Microsoft Excel data formats impose the following limitations on the total number of rows and columns in a worksheet:

File format	XLS	XLSX
Total number of columns	256	16,384
Total number of rows	65,536	1,048,576

If the number of exported rows or columns exceeds the predefined limit, the TreeList throws an exception and cancels the export operation.

Set the SuppressMaxRowCountError property to true to suppress the exception and export the maximum available number of rows. Extra rows are not exported.

async Task ExportXlsx_Click() {
    await MyTreeList.ExportToXlsxAsync("ExportResult", new TreeListXlExportOptions() {
        SuppressMaxRowCountError = true
    });
}

To suppress the maximum column count exception, use the SuppressMaxColumnCountError property.
