Question: I am using FormView control, and I want to programmatically insert null value in OnItemInserting and OnItemUpdating event, by NewValues dictioanry in FormViewUpdateEventArgs parameter. But if I use

```
protected void FormView_ItemUpdating(object sender, FormViewUpdateEventArgs e)
{
    e.NewValues["EntityFrameworkEntityPropertyName"] = null;
}

```

such modification is ignored, database column is not updated and keeps its old value. EntityFramework entity property is: Type Int32, Nullable True, StoreGeneratedPattern None. 

If I bind TextBox control directly to property by Bind(), nulls are inserted well. Also if values are different from null, everything works fine.

How can I insert null value?

Answer: 
To remove you can simply use:

```
[myTextField removeFromSuperview];

```
```
[myTextField removeFromSuperview]

```
