Hello,

When I use the code below to set column(1) of my GridView to invisible, I receive the following error:

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Code:

Dim ds As New DataSet
        ds.ReadXml(Server.MapPath("~/App_Data/Country.xml"))
        GridView1.DataSource = ds.Tables(0)
        GridView1.DataBind()
        GridView1.Columns(1).Visible = False


How do I fix this problem?

Thanks,

You should do this on the RowCreated event like this:

Protected Sub GridView1_RowCreated(ByVal sender As System.Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowCreated
            e.Row.Cells(1).Attributes.Add("style", "display:none")
    End Sub

U can check it with
Gridview1.Columns.Count
Count might have only one.

Hi,
The code works but I need to achieve this by code. I have one grid displaying data from several xml files, the column I need to hide will depend on which xml file is being displayed.

Thanks,

Victor

Never mind my last post, I will add if statements for different xml files being loaded in the code to hide different columns.

Thanks,
