Hi All
I have 2 dropdown menus that are databound. The second dropdown list is bound to the first dropdown menu's selectedvalue.
I have created the databinding within the code behind for various reasons and for some reason when selecting a different value from within my first menu, the second menu updates accordingly but still stores the previous items too rather than refreshing and just storing the new selected data.
When I set up the databinding using SQLDatasource controls the second list updates without storing the dregs.
Please could anyone let me know what I could be missing...
Code:
Protected Sub Menu1_SelectedIndexChanged
(ByVal sender As Object, ByVal e As System.EventArgs)
'database connection class/ function
Dim Menu2Populate As New dbclass()
Menu2Populate.Sproc = "strored procedure"
Menu2Populate.CustomerID = Menu1.SelectedValue
Menu2.DataSource = Menu2Populate.RetrieveMenu2data
Menu2.DataBind()
End Sub
Many thanks
