and here is the code for buttonclick:
protected void Button1_Click(object sender, EventArgs e)
{
string qwe = TextBox1.Text;
string ert = TextBox2.Text;
string filename = @"D:\\ExcelOpenXmlWithImageAndStyles.xlsx";
CreateExcelOpen exp = new CreateExcelOpen();
exp.BuildWorkbook1(filename);
}
And these are my requirements:
1.I need to pass the values of two textboxes to the two cells(which now contain values 12334 and 124515).
2. The heading column does not adjust itself to accomodate the values which i have provided(Retail customer group etc).Please suggest the modifications required in this class to enable the autofit.
Thank you for your time.
