How can I force a TextBox's DataSource to update after a change in value through code?

I am binding a TextBox's text property to a field value in a DataTable as such:

With control.Item_Full_Description
     .DataBindings.Add("Text", mdtItemMstr, "Item_Full_Description", True)
End With

When I make changes to the TextBox manually they are detected and updated in the data source, thus a save to the database is accurate. If I make the change behind the scenes, however, the data source is not updated and a save to the database results in the old value being saved back. Here is how I am updating the TextBox in the code:

Item_Full_Description.Text = _mItem_mstr_c + " - " + Item_Description.Text + " - " + Unit_of_Measurement_UOM.Text

I am clearly missing a fundamental step to have this change reflected in the data source, however a search online is not proving to be useful. Maybe I am just uncertain of what to search so any advice or even guidance would be appreciated. Thanks.

Since you are updating the control from code you need to force the binding source to update.

Look into the BindingContext class... http://msdn.microsoft.com/en-us/library/system.windows.forms.control.bindingcontext%28v=vs.110%29.aspx

BindingContext([data source]).EndCurrentEdit()
