c# - save row in one table to another table using linq -

-

Did you know that when you drag and drop a user from the data source window? Visual Studio automatically creates a DataContext (in view of the XAML) page to.This DataContext is set to a CollectionViewSource on to force the new elements and the CollectionViewSource it draws went informed of a dataset. The same datasets take you to the table by dragging and dropping.

In my scenario this is what it has been created: 

   & Lt; TextBox x: Name = "Paswardtekstboks" Text = "{Binding password mode = Dowa, NotifyOnValidationError = true, ValidatesOnExceptions = true, UpdateSourceTrigger = PropertyChanged}" / & gt; & Lt; / Grid & gt;

This is considered as a very simple signup page, using an administrator simply scrolling, clicking on the approval button, or clicking on the Reject button to accept and reject the registration. Could.

This is the thing that I am using the MVVM pattern. This means that the Properties boxes are bound to upwards, the CollectionViewSource class, which is in the place where my problem begins.

I need to save this information from the 'sign-up' table on those tables.

  1. Since the properties have been forced to text boxes, there is a visual problem in the collection, is there any way to bring their values ​​from there?
  2. I looked through the solution explorer and did not get any actual class called the signup vista. If it is not, then how is it referenced and why is it called a class?
  3. Is it a placeholder unless I do my archive collections ViewSource class? Will it be more viable?

What I've tried so far is the following method that wants to save information from the table of users in the table of the table: 

  PrivateCreateCommandExecute Object Ultimate) {myAppEntities Reference = New MyAppEntities (); Myapp.signup signup = new signup (); {MyApp.user user = New Medicare 2.Sear {firstname = signup.first, surname = signup.last, username = signup.username, password = signup.password,}; // Change the database changes in context.users.Add (user); Context.SaveChanges (); MessageBox.Show ("saved"); } Hold (Exception pre) {Message Box. Show (ex.Message); }}

The problem with the above method is that this signup creates a new event in the class which I am saving, so all the information I am receiving is empty I therefore get the verification error basically. Any help will be very much appreciated.

You can select the registration as the commandParameter < / Code> Whatever the control is implementing the SaveCurrent command, then you can enter object param / /> back to signup and from there Can remove the value.

javascript - data.match(var) not working it seems -

OK, I have this small block code, which is to scanned a number on the website, but for some reason There is a hip that it is not scanning at all. var regenges = / \ & lt; Span class = "currency-robux" data-to-"item-private-value-price" & gt; ([\ D,]) \ & LT; \ / Span \ & gt; /; Var ValueCiling = Data. Match (reggae); Value-song = number (value slicing location (",", "")); Is there anything wrong with that? This is related to the if statement if (value sling and lieutenant; = price watching) { < P> A function calls to move from there, but for some reason it does not seem to run at all. So I think the Regex is wrong but I'm not sure how. (There is a variable in PriceWinking , this is a snippet from the code.) On the website, I'm trying to remove it. & lt; Span class = "robux" data-plus = "item-privatesale-price" & gt; 115 & lt; / Span & gt; Keep in mind
