How to "refresh" a Datagridview?

Hi
In Form1 I have a Datagridview showing the content of a table from DataBase.

In Form2 I add or modify a row in that table. So, when I get back to Form1 I would want the DataGridView get updated automatically.

To populate the DGV I use a Linq To Sql query:

Code:

---

Dim Query = From .....
Me.DGV.DataSource = Query

---

or

Code:

---

Dim Query = From .....
Me.BindingSource1.DataSource = Query
Me.DGV.DataSource = Me.BindingSource1

---

I have been trying to use:
BindSource (as DataGridView.DataSource)
BindingSource.ResetBinding(False)
DGV.Refresh()
etc...

Also, I added a new row in the same Fomr1 and nothing happens.

Thanks for advance !!!

Be sure you really modify the db and not only a local in memory representation of it in form2.

Then, you first, you should make form 2 inform form 1 it is time to reload (requery) data.

To refresh data in form 1 use

Code:

---

BindingSource1.ResetBindings(false)

---

On how to inform form1 from form2 it is time to refresh, have a look at delegates and callbacks. But take this advice: look also at async operations...
