Gridview - Accessing a field value in current rowHi all,
I can currently access a row value using the following: GridViewRow g = g.Rows[1]; string s = g.Cells[1].Text; However, I need this particular field to be invisible. I only put it in the grid because I need to do stuff with its value, but, the user doesn't need to see it. However, when a field is invisible the Cells collection doesn't see it. Anyone have any suggestions? TIA, Joe Hi,
invisible fields are not kept in ViewState. Therefore you need to add the field to DataKeyNames of the GridView so that it is kept over postbacks while the field is invisible.

to doubt and you can have multiple key columns with GridView. It's just the simplest solution :-) Check following ASP.NEt Forum post for reference: http://forums.asp.net/937935/ShowPost.aspx If you want to, you can try having a TemplateField, a Label in it and bind the field as Text to that Label. Then you could access the value from that field.
