How to delete listview row and update database table at the same time..

Hi,

I have a listview that has this selectcommand:

SelectCommand="SELECT * FROM [XXX] WHERE ([id] = @id) ORDER BY [seqNr] ASC"

I have no problem deleteing a row in my listview:

DeleteCommand="DELETE [XXX] WHERE ([ControlId]=@ControlId)"

I want the seqNr to be updated at the same time as the row is deleted. For example I have a lisview with 10 rows and I delete row 7, then I want to the column seqNr in my table to be updated. I have tried something like this:

Dim iSeq As Integer
                Dim iCtlid As Integer

                Dim i As Integer
                Dim test As String
                test = ListViewFormControls.Items.Count

                For i = 0 To ListViewFormControls.Items.Count - 1
                    iCtlid = ListViewFormControls.DataKeys(i).Value
                    iSeq = i + 1
                    UpdateFieldSequence(iCtlid, iSeq)
                Next

But this fires before the actual delete, so the column seqNr is a mess...

I hope you understand my problem.

Is your code in the ItemDeleted event handler?

Yes

Protected Sub ListViewFormControls_ItemDeleting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewDeleteEventArgs) Handles ListViewFormControls.ItemDeleting

I have no problem getting it to work one by one, but I can't make it happen at the same time  by clicking the delete button.

I'm confused. You answered that the code is in the deleted event, but are showing the deleting event.  The deleting event occurs before the record is removed, thus renumbering will not work.  The deleted event occurs after the record has been removed.

Try ...

Protected Sub ListViewFormControls_RowDeleted(ByVal sender as Object, ByVal e As System.Web.UI.WebControls.ListViewDeletedEventArgs) Handles ListViewFormControls.ItemDeleted

Sorry my bad, I mixed it up...

It works like a charm now.
