and this is the function for button click :
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);
}
here 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.
In Your
CreateContentmethod you have hard coded values like:change it with values of text boxes that you want to show.
for setting width of headers, you will have to add columns along with Cells as you need columns to define the width, following article will be of some help for you:
