Where is the code behind the Add button for Winform BindingNavigator Control?

Question

Is there a code for the Save button, but I don’t see the code behind the Add button, although the button works?

So, what would it be, how do I want to create my own not from scratch?

Thanks.

Answer 1

The way to connect the add button to the base type or BindingSource. Based on the behavior that I saw yesterday, if the base list was bound to a type with an empty constructor, it was enabled, and if not, the button was disabled. So what it should be

this.bindingNavigator1.BindingSource.AddNew();
this.bindingNavigator1.BindingSource.MoveLast();

if you have something where you don't want the default constructor to use something like this:

this.bindingNavigator1.BindingSource.Add(new T(1));
this.bindingNavigator1.BindingSource.MoveLast();

The save code will be like this:

,

DataSet.AcceptChanges();

tableAdapters

var myTableAdapter=new DataSet1TableAdapters.assetTableAdapter();
myTableAdapter.Update(DataSet);

/.
