What do you mean, when you change the data source of the grid? Is it
just
the one statement you've given?

One thing is if that is a dataset, you need to specify which table in
the
dataset the binding source should use, like this:

 TblFeedbackBindingSource.DataSource = _ds.Tables("Customers")

If it's strongly typed, you can access the table name directly,
something
like this:

 TblFeedbackBindingSource.DataSource = _ds.CustomerTable

Hi Jakob,

I performed a test based on your description but could not reproduce your
problem.

When the DataSource or DataMember property of a BindingSource component is
changed, and the BindingSource component has been set as the data source of
a DataGridView,  data binding will update the data in the DataGridView
automatically and we needn't set the DataSource property of the
DataGridView control once again.

Note that if you change the DataSource property of the BindingSource
component, to get the data displayed correctly in the DataGridView control,
you should ensure that the new dataset instance has a DataTable with the
same name and schema as the previous dataset instance does.

Beside the above possibility, I think other possible reasons of your
problem may be that the DataSource property of your DataGridView control
has been changed somewhere else or the the BindingSource component whose
DataSource property you changed is not the one that the DataGridView
control is bound to.

If the problem is not still solved, you may send me your sample project
that could just reproduce the problem. To get my actual email address,
remove 'online' from my displayed email address.

Sincerely,
Linda Liu

If the dataset has exactly the same schema but the refresh doesnt happen
automatically, call:

TblFeedbackBindingSource.ResetBindings(false)

My own fault!

Today I detected an event handler that had a line of code setting the grid
datasource to nothing, which of course explains all ..... !

Sorry about that.
