Question

In a form, I have a TextBox Binding an Object on its member property “Title”. Along with it is a “Save” button to test the binding.

Seems like the underlying object property does not get updated unless the textbox loses focus. But there no form.ActiveControl.Blur() for use. Besides, this does not seem like a sound hack.

Anyway to do this better? Thanks.

EDIT: Sorry for not being clear. My question is in the title: “How to commit a TextBox”. I use the term “commit” from the DataGridView commit and BindingSource commit. And it’s in WinForms. (Have never worked with WPF, so it didn’t occur to me. Sorry).

The actual scenario I have is I have a bunch of TextBox binded to property of a single Object. The user enters values in all the TextBox and when the user clicks save (toolbar button), the last TextBox is still in focus (or in editing mode) hence the save will not capture the last value in the last textbox.

I want to find the correct way to “commit” the textbox value just before saving.

Thanks.

Since the question has been updated to indicate this is WinForms, you’ll need to handle things a little differently than if this were a WPF application. Fortunately, it turns out that the solution is very simple.

Whenever the user clicks on the “Save” button (so, say, in your Save button’s Click event handler), you need to call the EndEdit method on your BindingSource. This will cause all pending changes to be committed to the underlying data source, exactly what you were hoping to accomplish.

Also see the relevant documentation on MSDN for more details.
