Hi,

I have two forms. I call FORM2 from FORM1. When in FORM2 and apply some changes with button control i need refresh Datagridview in FORM1 before exit FORM2.


Call FORM2 from FORM1:

Dim f As New form2(myparameter)
f.ShowDialog()

Code for Button in FORM2:

 Dim f1 As New form1
 F1.ShowGridRecords()  ' Procedure to bind grid
 f1.MyDgView.Refresh()

But with this approach not work, can someone help.

best regards

You would need to create an event on the sub form that the parent would subscribe to.  When that event is triggered on the the sub form, then you can trigger a refresh method.

Here is an example:
'Here is the code for parent form
Public Class ParentFormClass
    Public Sub MyLogic()
        MessageBox.Show("My Logic is Running!")
    End Sub

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        MyLogic()
    End Sub    

    'This is the way that you pass an instance of parent to child
    Private Sub ShowChildFormButton_Click(sender As Object, e As EventArgs) Handles ShowChildFormButton.Click
        Dim f As New ChildFormClass(Me)
    End Sub
End Class

'Here is the code for child form
Public Class ChildFormClass
    Private MyParentForm As ParentFormClass

    Public Sub New(form As ParentFormClass)
        ' This call is required by the designer.
        InitializeComponent()
        ' Add any initialization after the InitializeComponent() call.
        MyParentForm = form
    End Sub

    Private Sub CallParentFormMethodButton_Click(sender As Object, e As EventArgs) Handles CallParentFormMethodButton.Click
        MyParentForm.MyLogic()
    End Sub 
End Class
