Problem deleting Last Row in ListView

[A_PK]

I am writing mobile application using Vb.net

when i click the last row of list view, and try to delete it....
will promtpy the following message "Additional information:
ArgumentOutOfRangeException"

what does that mean ?

I can delete any row without problem but except last row only....

[Daniel Moth]

Show us the code... If you are using the index for deleting you should be
adjusting by -1

Cheers
Daniel

A,

Test in your delete method if there are still enough items to delete, this
can occur when you have not done that and a delete button is pushed twice at
the end.

I hope this helps?

If you have 5 rows delete row number 4 as the rows are zero based. It means:
Rows: 0,1,2,3,4 (5 rows)

The following is the code that I delete my last row in List VIew

-----
With ListView1.FocusedItem

ListView1.Items.Remove(ListView1.Items(.Index))

End With
------

How can I set the index to -1 after i delete ?
if i only have 1 row in ListView, by adjusting index to -1 will still face
the problem since there is no record.

Pls guide

If you allow only one item to be selected you can use this line:
If (ListView1.SelectedItems.Count > 0) Then
ListView1.SelectedItems(0).Remove()
End If

After you have deleted your selected row (last row), the index:
listView1.SelectedIndices(0)
Will be set automatically to -1 becasause no record is selected.

If I understand you correctly, you have code in the SelectedIndexChanged
event handler that assumes there is always a selected/focused item; if that
is the case simply check if indeed there is a selected item and return if
there isn't, e.g.:

'// in SelectedIndexChangedEvent make this the first line
If (ListView1.SelectedItems.Count = 0) Then Return

Then just add this line in the SelectedIndexChanged sub as the first line:
If (listView1.SelectedItems.Count = 0) Then Exit Sub
