How to Change the Row Height for the Exported Excel Sheet in WinForms DataGrid?

This example illustrates how to change the row height of the excel sheet exported from the WinForms DataGrid (SfDataGrid) and also shows how to auto adjust the row height of the exported excel sheet based on its content.

You can change the row height of the exported excel sheet using Worksheets.UsedRange.RowHeight property.

C#

private void ExportToExcel_Click(object sender, System.EventArgs e)
{
    ExcelExportingOptions options = new ExcelExportingOptions();
    var excelEngine = sfDataGrid.ExportToExcel(sfDataGrid.View, options);
    var workBook = excelEngine.Excel.Workbooks[0];
    
    //Set row height.
    workBook.Worksheets[0].UsedRange.RowHeight = 30;
 
    SaveFileDialog sfd = new SaveFileDialog
    {
        FilterIndex = 2,
        Filter = "Excel 97 to 2003 Files(*.xls)|*.xls|Excel 2007 to 2010 Files(*.xlsx)|*.xlsx",
        FileName = "Book1"
    };
 
    if (sfd.ShowDialog() == DialogResult.OK)
    {
        using (Stream stream = sfd.OpenFile())
        {
            if (sfd.FilterIndex == 1)
                workBook.Version = ExcelVersion.Excel97to2003;
            else
                workBook.Version = ExcelVersion.Excel2010;
            workBook.SaveAs(stream);
        }
 
        //Message box confirmation to view the created spreadsheet.
        if (MessageBox.Show("Do you want to view the workbook?", "Workbook has been created", MessageBoxButtons.OKCancel) == DialogResult.OK)
        {
            //Launching the Excel file using the default Application.[MS Excel Or Free ExcelViewer]
            System.Diagnostics.Process.Start(sfd.FileName);
        }
    }
}

VB

Private Sub ExportToExcel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button2.Click
    Dim options As New ExcelExportingOptions()
    Dim excelEngine = sfDataGrid.ExportToExcel(sfDataGrid.View, options)
    Dim workBook = excelEngine.Excel.Workbooks(0)
       
    'Set row height.
    workBook.Worksheets(0).UsedRange.RowHeight = 30
 
    Dim sfd As SaveFileDialog = New SaveFileDialog With {.FilterIndex = 2, .Filter = "Excel 97 to 2003 Files(*.xls)|*.xls|Excel 2007 to 2010 Files(*.xlsx)|*.xlsx", .FileName = "Book1"}
 
    If sfd.ShowDialog() = System.Windows.Forms.DialogResult.OK Then
       Using stream As Stream = sfd.OpenFile()
       If sfd.FilterIndex = 1 Then
          workBook.Version = ExcelVersion.Excel97to2003
       Else
          workBook.Version = ExcelVersion.Excel2010
       End If
           workBook.SaveAs(stream)
       End Using
 
       'Message box confirmation to view the created spreadsheet.
       If MessageBox.Show("Do you want to view the workbook?", "Workbook has been created", MessageBoxButtons.OKCancel) = System.Windows.Forms.DialogResult.OK Then
          'Launching the Excel file using the default Application.[MS Excel Or Free ExcelViewer]
          System.Diagnostics.Process.Start(sfd.FileName)
       End If
    End If
End Sub

You can use AutofitRows method to adjust the row height of the exported excel sheet based on the content.

C#

private void ExportToExcel_Click(object sender, System.EventArgs e)
{
    ExcelExportingOptions options = new ExcelExportingOptions();
    var excelEngine = sfDataGrid.ExportToExcel(sfDataGrid.View, options);
    var workBook = excelEngine.Excel.Workbooks[0];
 
    //Row height will be set based on the content.
    workBook.Worksheets[0].UsedRange.AutofitRows();
 
    SaveFileDialog sfd = new SaveFileDialog
    {
        FilterIndex = 2,
        Filter = "Excel 97 to 2003 Files(*.xls)|*.xls|Excel 2007 to 2010 Files(*.xlsx)|*.xlsx",
        FileName = "Book1"
    };
 
    if (sfd.ShowDialog() == DialogResult.OK)
    {
        using (Stream stream = sfd.OpenFile())
        {
            if (sfd.FilterIndex == 1)
                workBook.Version = ExcelVersion.Excel97to2003;
            else
                workBook.Version = ExcelVersion.Excel2010;
            workBook.SaveAs(stream);
        }
 
        //Message box confirmation to view the created spreadsheet.
        if (MessageBox.Show("Do you want to view the workbook?", "Workbook has been created", MessageBoxButtons.OKCancel) == DialogResult.OK)
        {
            //Launching the Excel file using the default Application.[MS Excel Or Free ExcelViewer]
            System.Diagnostics.Process.Start(sfd.FileName);
        }
    }
}

VB

Private Sub ExportToExcel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles button2.Click
    Dim options As New ExcelExportingOptions()
    Dim excelEngine = sfDataGrid.ExportToExcel(sfDataGrid.View, options)
    Dim workBook = excelEngine.Excel.Workbooks(0)
 
    'Row height will be set based on the content.
    workBook.Worksheets(0).UsedRange.AutofitRows()
 
    Dim sfd As SaveFileDialog = New SaveFileDialog With {.FilterIndex = 2, .Filter = "Excel 97 to 2003 Files(*.xls)|*.xls|Excel 2007 to 2010 Files(*.xlsx)|*.xlsx", .FileName = "Book1"}
 
    If sfd.ShowDialog() = System.Windows.Forms.DialogResult.OK Then
        Using stream As Stream = sfd.OpenFile()
            If sfd.FilterIndex = 1 Then
                workBook.Version = ExcelVersion.Excel97to2003
            Else
                workBook.Version = ExcelVersion.Excel2010
            End If
            workBook.SaveAs(stream)
        End Using
 
        'Message box confirmation to view the created spreadsheet.
        If MessageBox.Show("Do you want to view the workbook?", "Workbook has been created", MessageBoxButtons.OKCancel) = System.Windows.Forms.DialogResult.OK Then
           'Launching the Excel file using the default Application.[MS Excel Or Free ExcelViewer]
           System.Diagnostics.Process.Start(sfd.FileName)
        End If
    End If
End Sub
