Raising Events

-
In Default.aspx I have a user control (<WI:editBOM runat="server" id="ctlEdit" />)  I want to refresh  the ctlEdit dropdownlist when another control fires (BOM.ascx)
 
So in DEFAULT.aspx I add this sub

Private Sub ctlNew_drpBOM_Change() Handles ctlNew.drpBOM_Change
ctlEdit.drpbomChange()
End Sub

In the EDITBOM.ASCX file I add this subroutine essentially rebinding the dropdownlist

Public Sub drpbomChange()

drpBOM.DataSource = VendorBid_Data.itemAttributesvb.getValidBOMStyles()
drpBOM.DataBind()
drpBOM.Items.Insert(0,

"Choose Style")

End Sub

In the BOM.ASCX file I declare the event and raise the event:

Public Event drpBOM_Change()

I raise the event at the point I want to fire it....

RaiseEvent drpBOM_Change()

Thus we have a page that holds two controls - when one dropdownlist or event fires then the other control dropdownlist is refreshed.  This enables me to load up my controls on the page but if circumstances change and the dropdownlist on one needs to be refreshed then I have control over that single page event.

Sorting Ascending and Descending

Toggling the direction of your datagrid sort is easy using a session to remember which direction you sorted last.   You will want to declare an empty string in the top of your page       Dim SortField As String Then on your sort command add this logic - Example of entire command Private Sub dgTaskExceptions_SortCommand( ByVal source As Object , ByVal e As System.Web.UI.WebControls.DataGridSortCommandEventArgs) Handles dgTaskExceptions.SortCommand     SortField = e.SortExpression If Session( "toggle" ) = True Then SortField += " DESC" Session( "toggle" ) = False Else SortField += " Asc" Session( "toggle" ) = True End If Dim orderstring As String = SortField 'REBIND dgTaskExceptions.DataSource = POTracking_Data.tracking.getSampleTasks(orderstring) dgTaskExceptions.DataBind() End Sub   In my datalayer I add this logic to my query and pass in an OPTIONAL value Dim orderbyString As String = String .Empt
