ASP.NET GridView UserControl

I want to make an ASP.NET user control with only a gridview on it.

My usercontrol must behave the same as a normal gridview, with some
extra
properties and methods (for security purposes, such as: invisible,
readonly etc..)

I can not inherit the gridview from webcontrols.gridview because this
causes an error.
(Compile error: "property 'SupportAutoEvents' cannot be declared
'Overrides' because it does not override a property in a base class"),
so I made my own properties and methods.

I can bind data to myGridView and this works fine, but when I want to
customize the columns (at run-time). Such as headertext, first column
invisible etc...
This is the property for the columns:

Property Columns(ByVal index As Integer) As
System.Web.UI.WebControls.DataControlField
        Get
            Return GridView1.Columns(index)
        End Get
        Set(ByVal value As System.Web.UI.WebControls.DataControlField)
            GridView1.Columns(index).Visible = value.Visible
        End Set
End Property

This doesn't work, can anyone tell me why?

How can I setup usercontrols with only 1 control and inherit all
properties, methods and events from this 'base' control, so I only have
to add my own properties?
This because I also have to make usercontrols of textbox, buttons
etc...

Thanx in advance...

Below is an example of someone that developed his own datagrid based on
the .net datagrid.
That should give you some hints on how to do this.
