I'm trying to write a
web part that access lists and add items in a specific list.
The user modifies
the web part and type in List Name,
the web part has 3 TextBoxs and a Button.
The user should enter data and press
the save button, that should update
the list and add these data in a new record.
I'm using
the following code to build my
web part, but
the save button doesn't update
the list. I don't know what's wrong it just reload
the page and add nothing.
Edit: BTW
the list am trying to update has three columns, First Name, Last Name, and Email, respectively.
