Hiding item in DataGrid

I have a DataGrid that displays 3 columns from a list of Files in a
Directory. The first column is a HyperLink that displays the file name with
a link to another page and querystring. Below is the DataGrid and below
that is the ItemDataBound code that is not hiding the file named
"Thumbs.db". What am I doing wrong to hide that cell? p.s. I would prefer to
hide the whole row. Thanks.

are you sure that this is correct?
If value = "ShowDocs.aspx?doc=Thumbs.db" Then

To hide the whole row you need to set

for (int i = 0; i < e.Item.Cells.Count; i++)
e.Item.Cells.Visible = true;
