index out of range must be a non negative and less than trhe size of the collection.
My delectecommand is firing and e.item.itemindex is returning the correct row number, non -ve , the collection, i do not know what collection.
and what is it about hiding the datekey column.
please help assignement due on the 23rd april 2006.
code below/
Dim dr As DataRow
'creating dt on the fly with new dataview
' Define the columns of the table.
dt.Columns.Add(new DataColumn("IntegerValue", GetType(Integer)))
dt.Columns.Add(new DataColumn("StringValue", GetType(String)))
dt.Columns.Add(new DataColumn("CurrencyValue", GetType(Double)))
------
'setting the datakey column as the first column
Dim keys(1) As DataColumn
keys(0) = dt.Columns(0)
------
datagrid_deletecommand section
Dim row As DataRow
row = dt.Rows.Find(ItemsGrid.DataKeys(e.Item.ItemIndex))
' Delete the item selected in the DataGrid from the data source.
If Not row is Nothing Then
dt.Rows.Remove(row)
End If
' Save the data source.
Session("Source") = dt
' Create a DataView and bind it to the DataGrid control.
Dim dv As DataView = New DataView(dt)
ItemsGrid.DataSource = dv
ItemsGrid.DataBind()
another datagrid program not working as well
cartview is a dataview
' Remove the old entry and clear the row filter.
CartView.RowFilter = "Item='" & item & "'"
If CartView.Count > 0 Then
CartView.Delete(0)
