Refresh data in ObjectDataSource in button event handler

I have a user control with GridView and  ObjectDataSource. I also have a button, that should update database and I wanted to refresh GridView in the same click callback.

And it's easy to do- call ObjectDataSource.Select and then GridView.DataBind:

        Protected Sub btn1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn1.Click

 â€˜method to update database is omitted for simplicity

            Me.ObjectDataSource1.Select()

            Me.GridView1.DataBind()

        End Sub

Update: As I was adviced by Bob Riley, call to GridView1.DataBind()is enough.

I don't think you need to call the ObjectDatasSurce1.Select(). Just the call to the GridView.Databind() will be fine (it will initiate the call to the select statement). I think, if you call both, the 'Select' method for the ObjectDataSource is also called twice.

Bob Riley,

You are right. Call to ObjectDatasSource1.Select() is redundant.
Thanks for letting me know.
Michael.
