Hi,

I have exported the gridview value to an excel file.But when i tried it to save using a save dialog box,it's not working,but no error is showing.Kindly rectify my mistake.The code i am using is given below.

C#

private void button2_Click(object sender, EventArgs e)
       {

           string sd;
           saveFileDialog1.ShowDialog();
           saveFileDialog1.InitialDirectory = "c:";
           saveFileDialog1.FileName = "";
           saveFileDialog1.Filter = "Excel File|*.xls|All Files|*.*";







           Microsoft.Office.Interop.Excel.ApplicationClass ExcelApp = new Microsoft.Office.Interop.Excel.ApplicationClass();
           ExcelApp.Application.Workbooks.Add(Type.Missing);


           ExcelApp.Columns.ColumnWidth = 20;


           for (int i = 1; i < dataGridView1.Columns.Count + 1; i++)
           {
               ExcelApp.Cells[1, i] = dataGridView1.Columns[i - 1].HeaderText;
           }


           for (int i = 0; i < dataGridView1.Rows.Count - 1; i++)
           {
               for (int j = 0; j < dataGridView1.Columns.Count; j++)
               {
                   ExcelApp.Cells[i + 2, j + 1] = dataGridView1.Rows[i].Cells[j].Value.ToString();
               }
           }


           sd = saveFileDialog1.FileName;
           ExcelApp.ActiveWorkbook.SaveCopyAs(sd);
           ExcelApp.ActiveWorkbook.Saved = true;
           ExcelApp.Quit();
           MessageBox.Show("Excel file created");

This looks logical to me. What does 'not working' mean, do you get any file saved at all ? Do you need to set which workbook is 'active' ? Does SaveCopyAs return anything ?

not working means,if i selected the c: drive and saved,and the file is not there.But no error is showing.

OK - then can you check in debugger or code what the ActiveWorkbook is ? Does SaveCopyAs return any value for success, or is there a property you can check to find out what went wrong ? Is SaveCopyAs the only save method you can call ?

I have tried some other save methods,but shows some errors.When i tried without the savedialogbox,the file is created.

Solution 1

Why not use SaveAs[^] instead.

Also using debugger check that you have given a valid path and file name to sd variable.

You can also wire BeforeSave[^] to see what happens before the save operation.
