Hi currently I am doing a online calendar project.
There ia a drop-down list tied to reminder(label) and when i select any of the reminder options in the ddl and
click on downlaod pdf button, there should be a message box that tells users they are not allow to select any of the reminder options
for PDF.
This is the code that i have entered:
protected void downloadPDFBtn_Click(object sender, ImageClickEventArgs
e) { //calls
the method to create the datatable
GetCustomMadeDataTable(); //calls
the method to generate the pdf from the
datatable GeneratePDF(table);
//popup error message when staff
choose one of the field under the Reminder field and click on the "download PDF"
button. if
(DropDownList1.SelectedItem.Value !=
null)
{
MessageBox.Show("There is no timetable available
for");
Response.Redirect("DownloadTimetable.aspx");
}
