form loading in vb.net

[Revathy Sesha]

hi.
i am developing a simple vb.net application. i have three forms in my app. the first form has 2 radio buttons from which i need to select one. based on the selection made in my next form a combobox ll be populated.so far so good.there is a back button on my 2nd form which when clicked redirects me to the first form. here when i select the next radio button the combo box in the next form does not populate accordingly. it still holds the old values.

i hope my question is clear.

this is the code i have in the first form.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim frm As Form2
        frm = New Form2()
        If RadioButton1.Checked Then
            passedtext = RadioButton1.Text
        ElseIf RadioButton2.Checked Then
            passedtext = RadioButton2.Text
        End If
        Me.Hide()
        frm.Show()
    End Sub

this is the code i have in the second form

Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        selectionstr = Form1.passedtext
        If String.Compare(selectionstr, "UNDER GRADUATE", True) = 0 Then
            'Dim obj As New Form1
            'obj.passedtext = Form1.RadioButton1.Text
            'If Form1.RadioButton1.Checked Then
            ComboBox1.Items.Clear()
            ComboBox1.Items.AddRange(New String() {"op1","op2"})
        ElseIf String.Compare(selectionstr, "POST GRADUATE", True) = 0 Then
            'ElseIf Form1.RadioButton2.Checked Then
            ComboBox1.Items.Clear()
            ComboBox1.Items.AddRange(New String() {"opt1","opt2"})
        End If
    End Sub

DO NOT use the form load event for populating control (on form2), becuase it will rise only 1 time (only when form opened).
Better create a new method on form2, and call it each time you want to pass some data from form1 to form2. This way you can execute it when ever you want.

thank u so much. i did as u told.i created a new method in form 2 and called it on the first form in a button click event given above. yet i get the same fault. it is not populating according to my selection.

Show me your code.

Use a form constructor, with parameters?
