Problems with Columns in Datagrids

[RichHamilton]

I have created a datagrid from a query, but when I display it it displays ALL the columns.

I want to hide some columns.

So I added this line
applicantsDataGrid.Columns[1].Visible = false;


But that gives me this error:
Inner Exception
----------------------------------------------

Message: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index
Source: mscorlib
Stack Trace: at System.Collections.ArrayList.get_Item(Int32 index)
at System.Web.UI.WebControls.DataGridColumnCollection .get_Item(Int32 index)
at MySiteDB.UI.Applicants.Default.Page_Load(Object sender, EventArgs e)
at System.Web.UI.Control.OnLoad(EventArgs e)
at System.Web.UI.Control.LoadRecursive()
at System.Web.UI.Page.ProcessRequestMain()

It's as if there are no columns, but all the columns ARE displayed.

Can anyone let me know what I'm doing wrong here?

Many thanks
Richard

When I create a datagrid, I always add AutoGenerateColumns="false" in the declaration.

<asp:Datagrid id="something" AutoGenerateColumns="false" runat="server" />

Then in the <columns> section I only specify the columns I want to display.

Hope this helps.

Great, I'll give this I try, it seems promising! (I guess I'll have to change the smily face though!)

Thanks I have it working now (simple really isn't it!)
