I need help getting my events set up correctly. Here's what's going on.

I have a project where I don't know the number or location of GridViews until the user selects some options. I need to do this all on one asp page.

I have figured out that I can create and populate a GridView dynamically and add it to a placeholder's controls.
ASP.NET
<asp:PlaceHolder ID="phTimeEntryDay" runat="server"></asp:PlaceHolder>

VB
Protected WithEvents gvTimeEntry As GridView = New GridView()
phTimeEntryDay.Controls.Add(gvTimeEntry)

I have added the edit and delete commands using code:
VB
Dim cColumn As New CommandField

cColumn.ButtonType = ButtonType.Link
cColumn.CancelText = "Cancel"
cColumn.UpdateText = "Update"
cColumn.EditText = "Edit"
cColumn.DeleteText = "Delete"
cColumn.ShowEditButton = True
cColumn.ShowDeleteButton = True
cColumn.ShowCancelButton = True

gvTimeEntry.Columns.Add(cColumn)

This does set up the correct postback javascript events, but nothing happens when I click the links and the page is posted back.

In another project where I created the gridview at design-time, I can't find any code created to handle the events that I can copy to my project that does everything at run-time.
XML
<asp:GridView ID="GridViewTimeSheet" runat="server" AllowSorting="True" AutoGenerateColumns="False"
    DataKeyNames="EmpPerNo,FromDate,ToDate,EntrySequence" DataSourceID="SqlDataSourcetimeEntry"
    ShowFooter="True" EmptyDataText="No Data Available.">
    <Columns>
        <asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
...

The only complete example I've found uses DataGrid in C# instead of GridView and there are enough differences in DataGrid and GridView that I can't adapt it completely.

Examples in VB or C# are fine if you have some.

Any help would be greatly appreciated.

Thanks,
Bryan Lee

Hi,
I can not see anywhere in your code to define grids events. Try to attach the desiger events by using AddHandler.

I'm lost at the disigner events. I can't figure out how the designer is handling events so I don't know what events to Add.

I found this reference at msdn that gives me examples of the events I need to handle and how to handle them.

Thank you, Aidin, for jogging my brain.

ARBebopKid, You are interesting man ;)
You ask a question and answer to yourself...

I find I often can't figure out the answers until I've already asked for help. :)
