Datatable Null Exception

Hello,

I'm creating a Windows application using Access database as the backend.

What I want to achieve is to search for an record in the database using a datagridview and update the table.
I have button for "Update", but it's throwing an Nullexception error. My database table does have null values in it.

Private dt as dataset = nothing
Dim dt As DataTable  = ds.Tables("TBL_ASSETS")
        Me.TBL_ASSETSDataGridView.BindingContext(dt).EndCurrentEdit()
        Me.TBL_ASSETSDataGridView.Update()

Can someone please assist?
Thank you

Check before End edit  like this..

if (control.DataBindings.Count > 0)
   {
      control.DataBindings[0].BindingManagerBase.EndCurrentEdit();
   }
