Question

I have a ListView with a template, it puts a bunch of data in, like X Y Z.

I want to hide show some columns based on criteria, so I have ItemDataBound event, but I don’t know how to get the actual listview row so I can do things to do it.

Any ideas?

You can access the ListViewItemEventArgs’ Item property to get at the current item (the one being bound to data).

The sample code below (which shows how to customize a ListView item in the ItemDataBound event) was taken from the MSDN documentation:

protected void ContactsListView_ItemDataBound(object sender, ListViewItemEventArgs e)
{
    Label EmailAddressLabel;
    if (e.Item.ItemType == ListViewItemType.DataItem)
    {
        // Display the e-mail address in italics.
        EmailAddressLabel = (Label)e.Item.FindControl("EmailAddressLabel");
        EmailAddressLabel.Font.Italic = true;

        System.Data.DataRowView rowView = e.Item.DataItem as System.Data.DataRowView;
        string currentEmailAddress = rowView["EmailAddress"].ToString();
        if (currentEmailAddress == "[e-mail]")
        {
            EmailAddressLabel.Font.Bold = true;
        }
    }
}
