I am having great difficulty with some code I have used (found the basic
idea on the internet). Basically, I have a tree whose node tags contain a
datarow. When a node is selected, the following code uses a dataview to
find the index of the row in the underlying datatable and then uses a
bindingmanagerbase to change the current position in the datatable. This
code seems to work fine - in debug the position changes - but controls that
are bound to the underlying datatable do not change their values.
The controls are bound in this way:
Me.txtTester.DataBindings.Add("text", mDS.Tables("Address"), "AddressLine1")
Here is the code which does the position change:
Dim bm As BindingManagerBase = BindingContext(mDS, "Address")
Dim view As DataView = New DataView(mDS.Tables("Address"))
view.Sort = "AddressID"
Dim therow As DataRow = Me.trResidence.SelectedNodes(0).Tag
Dim id As Integer = Integer.Parse(therow("AddressID").ToString)
bm.Position = view.Find(id)
Can someone help me fix this?
