Hai ,

I used gridview for student list , and export it to pdf.
But the 2nd column is not need to export. I make the gridview's 2'nd column visible false.

GrdStudent.Columns[2].Visible = false;

But pdf file contain this column. Can you help me to solve it.

Hai ,

is there any solution for this problem.

Thanks in advance.

might need to see more of the code than just that one line. That doesn't really tell anyone what is going on.

Hai ,
the code i used is:

protected void lnkStudentPDF_Click(object sender, EventArgs e)
    {
        SchoolCommon ObjCommon = new SchoolCommon();        
        try
        {
            GrdStudent.AllowPaging = false;
            DataTable dt = (ViewState["StudentList"]) as DataTable;
            GrdStudent.DataSource = dt;
            GrdStudent.DataBind();
                
                GrdStudent.Columns[2].Visible = false;
                ObjCommon.ExportToPDFnewFormat_WithButtons(GrdStudent, true, "Student Report", 6);
            }
            
            LblErr.Text = "Successfully Exported";
        }
        
        catch (System.Threading.ThreadAbortException lException)
        {

            // do nothing

        }

        finally

            HttpContext.Current.Response.ContentType = "application/pdf";
            HttpContext.Current.Response.AddHeader("content-disposition", "attachment; filename= SampleExport.pdf");
           
            
       
       
    }

It would probably be best to just not include that column at all if possible. Something like

for (int rowNo = 0; rowNo < noOfRows; rowNo++)
{
    for (int columnNo = 0; columnNo < noOfColumns; columnNo++)
    {
        if (columnNo != 2) // or whichever index you want to leave out.
        {
        // rest of code

might work. If the gridview already has columns defined you may need to clear them.

Hi,
Any one tell me how to hide columns
