Question

Hi,

I work on a asp.net 3.5 page with c# and use a Listview.

Please find ma code bellow.

Here my questions:

• I have a foraign key from catID to my table Categories, how I can insert the Name (stored in the table categories) insted the catID in the List view?
• The description is possible very very long, how can I make a substring on the description if its over 30 chars long and cut them off and enter the data?
• How I can manually insert a button / hyperlink after the data with the mainID and a link to a new page (which should displayed is detailed) ?
