How to delete rows in xml files based on rows selected from a Grid?

Hello,

How do I delete records in my Link.xml file when I delete a record from the grid control. For example if I select a row with Fuze_ID = 5, I would like to loop through my Link.xml file and delete all the records with Fuze_ID = 5.

I'm using the code code below, but I'm receiving the following error:
"Index 5 is either negative or above rows count"

On line: DV.Item(X).Delete()

Any ideas what's wrong with the code.

Thanks,

Victor

Dim dr As DataRow = dt.NewRow()    
dr("Link_ID") = linkID    
dr("Fuze_ID") = FuzeID    
dt.Rows.Add(dr)    
Next    
'Delete Selecete Record    
Dim X As Integer    
Dim DV As New DataView(dt, "Fuze_ID like " & "'" & C1TrueDBGrid.Columns(0).Value & "'" & "", Nothing, DataViewRowState.CurrentRows)    
 
For X = 0 To DV.Count - 1    
DV.Item(X).Delete()    
Next    
Dim DV1 As New DataView(dt, "", Nothing, DataViewRowState.CurrentRows)    
Dim FilteredDT As DataTable    
FilteredDT = DV1.ToTable    
'put data back to xml file    
FilteredDT.TableName = "Row"    
FilteredDT.WriteXml(Application.StartupPath + "\Link.xml")
