How to auto fit the rows or columns at runtime?

SfSpreadsheet provides support to fit the rows or columns based on its content at run time. You can fit the multiple columns by calling AutoFitColumns method of XlsIO’s IRange and then set the adjusted column width into the grid by using SetColumnWidth method of SpreadsheetGrid like below code example.

//For autofit  multiple columns,
Spreadsheet.ActiveSheet.Range["D1:G100"].AutofitColumns();
for (int i = 2; i <= 7; i++)
{
    Spreadsheet.ActiveGrid.SetColumnWidth(i, i, Spreadsheet.ActiveSheet.GetColumnWidthInPixels(i));
}
 
// For autofit multiple rows
Spreadsheet.ActiveSheet.Range["B1:B10"].WrapText = true;
Spreadsheet.ActiveSheet.Range["B1:B10"].AutofitRows();
for (int i = 1; i <= 10; i++)
{
    Spreadsheet.ActiveGrid.SetRowHeight(i, i, Spreadsheet.ActiveSheet.GetRowHeightInPixels(i));
}
