Description
There are several ways to export the RadGridView as a spreadsheet. This article shows you how to leverage the RadGridView's ExportToWorkbook method to make changes to the spreadsheet before saving as Excel xlsx file.
This article will show you how to add an extra row at the top of the speadsheet and insert a title.
Solution
The first step is to invoke the GridView's ExportToWorkbook method, optionally passing a GridViewDocumentExportOptions parameter.
var exportOptions = new GridViewDocumentExportOptions()
{
ShowColumnFooters = true,
ShowColumnHeaders = true,
ShowGroupFooters = true,
ShowGroupHeaderRowAggregates = true
};
Workbook workbook = MyGridView.ExportToWorkbook(exportOptions);
Workbook exported, you can now use the features of the Telerik Document Processing Libraries' RadSpreadProcessing to modify the document.
In this example, we are inserting a new row above the exported data to add a title.
// Step 1. Get the first worksheet
Worksheet worksheet = workbook.ActiveWorksheet;
// Step 2. Insert a new row at the top
worksheet.Rows.Insert(0);
// Step 3. Select the worksheet's A4 cell
CellSelection selection = worksheet.Cells[0, 4];
// Step 4. Insert the text "GridView Export" into the selected cell
selection.SetValue("GridView Export");
XlsxFormatProvider.
var dialog = new SaveFileDialog
{
DefaultExt = "xlsx",
Filter = $"Excel files (.xlsx)|.xlsx|All files (.)|.",
FilterIndex = 1,
FileName = "GridView Export"
};
if (dialog.ShowDialog() == true)
{
using (var output = dialog.OpenFile())
{
new XlsxFormatProvider().Export(workbook, output);
}
}
