Find control in formview 1

[blounty]

Hi all,

I am creating a page with a multiview which has 2 views. in one view there is a dropdownlist and in the other a formview. i want to be able to apply the selecteditem text to a label in the insert template of my formview. I understand that i have to use findcontrol() which i have done and works on the first try. if i press cancel in the insert template of my formview and try again i get a NullReferenceException.

my code behind is as follows:

Partial Class Vehicles
    Inherits System.Web.UI.Page
    Protected WithEvents branchid As New Label


    Public Sub NewVehicle_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles NewVehicle.Click

        Me.VehiclesMultiView.SetActiveView(FormEdit)
        Me.FormView1.ChangeMode(FormViewMode.Insert)
        branchid = CType(FormView1.Row.FindControl("BranchID"), Label)
        branchid.Text = Me.BranchDropDown.SelectedItem.Text

    End Sub
End Class

any ideas anyone its hurting my head!

Thanks all.

Which line do you get the error? Did you step through your code to find the problem?

branchid = CType(FormView1.Row.FindControl("BranchID"), Label)

on this line, it seems the second time round the branchid is nothing?

my experience has been that multiview views are mutually exclusive. the controls/data contained within each view are only accessible when the view is active. all other views/children are no instantiated.

This is the main difference between the multiview and the wizard control.
