reading hidden data from a gridview control

[Paul]

Hi I am trying to read hidden data from a gridview control. This works if
the data is visible but if the column is not visible it does not return
anything, thanks.
Int32 itemp = Convert.ToInt32(e.Row.Cells[6].Text);

If you hide the column with Visible=true, it won't be rendered and won't be
in the Cells collection. Add the column to the DataKeyNames, then you can
get it the DataKeys array.

Hi, thanks for the responses. I ended up converting the bound column to a
template column with a lable (lblDiscID) then used Int32 itemp
=Convert.ToInt32 ( (e.Row.Cells[6].FindControl("lblDiscID") as Label).Text);
which seemed to work. Guess there are a few ways to do it.

When you set a webcontrol's Visible property to false, it does not even get
rendered to the client browser.

Therefore, you will need to use CSS to hide it client-side.

Lots of examples of this are available:
