.NET Forum / ASP.NET / General / June 2008reading hidden data from a gridview control
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);  SignaturePaul G Software engineer. 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.

Therefore, you will need to use CSS to hide it client-side. Lots of examples of this are available: http://www.google.co.uk/search?sourceid=navclient&hl=en-GB&ie=UTF-8&rlz=1T4GZEZ_ en-GBGB252GB252&q=GridView+column+hide+display SignatureMark Rae ASP.NET MVP http://www.markrae.net 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. SignaturePaul G Software engineer. > > Hi I am trying to read hidden data from a gridview control.
