Gridview - Accessing a field value in current row

[Joe Reiss]

Hi 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.

This particular field is not a key for this grid. There is already another
field that is the key.

Any other suggestions?

Thanx,
Joe

That doesn't actually mind, GridView does not check for uniqueness, I dare
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:

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.
