1.)I have tried
Here Equation is database
EquationDataset is dataset
BasicInfoTableAdapter is dataadapter
BasicInfo is table

VB

Private Sub BindingSource1_ListChanged(ByVal sender As System.Object, ByVal e As System.ComponentModel.ListChangedEventArgs) Handles BindingSource1.ListChanged
'Checking for updation
        If EquationDataSet.HasChanges Then
            UpdatePending = True
        End If
    End Sub
Private Sub BasicDetailGrid_RowValidated(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles BasicDetailGrid.RowValidated
        If UpdatePending = True Then
            BasicInfoTableAdapter.Update(EquationDataSet.BasicInfo)
            UpdatePending = False
        End If
    End Sub

'I have read that ListChanged is fired before Rowvalidation for a while.

2.)I have also tried

VB

Private Sub BasicDetailGrid_RowLeave(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles BasicDetailGrid.RowLeave
        Try
            Me.Validate()
            Me.BindingSource1.EndEdit()
            Me.BasicInfoTableAdapter.Update(Me.EquationDataSet.BasicInfo)
            Me.EquationDataSet.AcceptChanges()
        Catch ex As Exception
            MsgBox("Update failed")
        End Try
    End Sub

Ganesh, use the "code block" feature to wrap your code, looks better now.
