Hello,
I am looking for a solution which can export a Number characters (19 digits) to be formatted as hyphen separated value when exported to excel output.
I tried below dataformat string in the .aspx file but it didn't help.
The code I used for data formating is as follows:
<asp:BoundField DataField="ORDER_NUMBER" HeaderText="Order Number" SortExpression="ORDER_NUMBER" DataFormatString = " {0}:00000-00000000-000000" />
Please help me to resolve this issue.
Thanks!
