ButtonLink in Datagrid passes ID to method

I use VB.NET

I have a datagrid which has been filled. I want to have a column which contains a LinkButton. When pressed that Link Button causes a Panel to appear that allows me to add records.

I know how to cause a Link Button to make the panel appear, disapear, etc.
But I want that Link Button to pass an ID from that datagrid record to that Panel (to a method for use in a database)

I know I can create a Hyperlink button to pass the ID in a URL, but I can't get that to work in this case.

I need an example of one of the following:

1) (Preferred) Link Button in DataGrid passes an ID to a method. Let's say the method just does a response.write of the ID.

2) Hyperlink passes BOTH the ID of a record in addition to an ID already in the URL.

Seems simple but I'm at a loss for the right solution.
Bonus points if both are answered and explained.

Also fell free to ignore the pageing stuff.

intItemIndex = e.Item.ItemIndex + (rptrList.CurrentPageIndex) * rptrList.PageSize

should just be

intItemIndex = e.Item.ItemIndex

if you aren't doing any sort of paging.

You gave me what I needed.
Essentially I was looking for this syntax:

Sub DataGrid (ByVal sender As Object, ByVal e As DataGridCommandEventArgs) Handles dgList.ItemCommand

and seeing the command argument could be retrieved with e.CommandArgument assuming e was a 'DataGrid'CommandEventArgs

Within the datagrid 'dgDistrictStudents' I have a column which includes the following:

<asp:TemplateColumn>
<ItemTemplate>
<asp:LinkButton ID="addStudentToSlot" runat="server" CommandArgument='<%# Container.DataItem("StuStudentID") %>' Text="| Add" />
</ItemTemplate>
</asp:TemplateColumn>

*In Code Behind*
Sub addStudent_Click(ByVal s As Object, ByVal e As DataGridCommandEventArgs) Handles dgDistrictStudents.ItemCommand
Dim intItemID As Integer
intItemID = e.Item.ItemIndex
Response.Write(e.CommandArgument)
End Sub

Thanks for the help!
