Unable to refresh DataGridView after updating database

Question

I've created a drag and drop DataGridView in Visual Studio 2013 and then bound it to a dataset using wizard. My problem is when I update the data in the database, the DataGridView does not get refreshed.

I have used this code : how ever data binding of the same Form's textboxes get refreshed and updated.

dataGridView1.Refresh(); 

and

dataGridView.Update(); 

EDIT: this code also doesnt work :

private void toolStripButton4_Click(object sender, EventArgs e)
    {
        bindingSource1.ResetBindings(true);                                 
    }

Answer 1

Following code worked write for me, first you should call the GetChanges() method on your data-set, then call the Fill(dataset.dataTable) on your dta-adapter.

            secaloFormulaDataSet.GetChanges();
            materialPriceTableAdapter.Fill(secaloFormulaDataSet.materialPrice);

this will immediately updates your datagridview and other controls that use data binding in your form.
