Web Forms :: Savechanges Not Available In Dataservicecontext?
Apr 30, 2010
I am New to this. I have a wcf data service(uses ado data entity) connected to silverlight application. The silverlight application displays the data through the wcf data services. I want the silverlight client to update any changes made by the user t o the database. I have looked at numerous examples of how to do this and pretty much have everything figured out except the part of savechanges.Everytime I try to use the savechanges method it throw an "savechanges is not a member of ilverlightapplication.servicereference.dataentities.Methods like addto or updateobject work just fine.Also,when I try to type savechanges() it is not available in the built in drop down box. I have provided a picture to exaplin better.

All I am trying to do is to make an update to an existing User and then save the changes to the database. I fooled around with different options and can see that I can make the change to the context during Page_Load, but it does not commit the changes to the Database.

I am using ADO.NET Entity Framework data model for my ASP.NET MVC project. I am trying to insert into multiple tables and called .SaveChanges() method. It doesn't throw any exception and doesn't insert into these tables.
What could be wrong here?
Object1 obj1 = new Object1();
obj1.TID = 300; //Auto generated but I am assigning the value.
obj1.TypeID = 1;
Object2 obj2 = new Object2();
obj2.TID = 300;
obj2.StartDT = DateTime.Now;
db.AddToObject1(obj1);
db.AddToObject2(obj2);
db.SaveChanges();
db.AcceptAllChanges();

SaveChanges can generate an UpdateException when an object added to the ObjectContext cannot be successfully created in the data source. This can happen if a row with the foreign key specified by the relationship already exists. When this occurs, you cannot use Refresh to update the added object in the object context. Instead, reload the object with a value of OverwriteChanges for MergeOption.
In a table, a foreign key column can have a single value multiple times. e.g. DepartmentID foreign key in Users Table: More than one User can have same DepartmentID foreign key.
So how can this cause an UpdateException ?

I have been presented with numerous word and excel docs. The goal is to put them online and bind to a database for the fields and also to store data for easy searching and reporting.
Has anyone done anything like this before?
I know the easy solution would be to create a database table for each particula form and also an ASP.net page for each form.
But then there are problems like printing and correct formating so it fits on the page, spaning multiple pages and so on.
And also is there any advice on how to write to PDF straight from the page?

I have a treeview named Treeview1 with checkboxes. I want the child checkboxes to be checked if parent is checked.
I am trying to use a simple code that I found on msdn :
[Code]....
For some reasons I got this error and I really dont understand why:
Type 'System.Windows.Forms.TreeViewEventArgs' is not defined.
warning BC40056: Namespace or type specified in the Imports 'System.Windows.Forms' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.

Really getting better with VS, but I've mostly been displaying data. I'm on a new project and now and I have a lot of data entry forms to create. I created a form to enter data into an access db and got it working. I thought it would be cool to add an edit button that fired a gridview to load on the same page, under my original forms, so that that they could load up the data and edit or delete mistakes. But when I try to update the gridview, it also tries to post the original forms (text boxes), which fail because there is no data in them, and I get an error.
What is the proper way to handle this in asp.net? I'm sure this is kind of a common issue. I've done some searching, but the search terms, like forms and gridview, are kind of generic and I'm not coming up with anything useful. I just need a more experienced person to point me in the right direction and I'll get it figured out.

I am using forms authentication, and for some reason it shuts off my images. I have tried putting them in the same directoy, and still nothing.
If I turn off forms authentication, they come back alive so I know my urls are correct.

In windows forms, there is the "show data sources" under the "data" menu item, and I love it because I can drag and drop the fields I need onto the form and it makes the control automatically.In web forms however, this option isn't there. Why? I try to drag and drop fields from the "server explorer" but it generates grids, I don't want grids I just want to drag and drop the text boxes or checkboxes etc.

Created in VS2008
The login page is created with the masterpage and it has the header picture.
After Logout or run FormsAuthentication.SignOut();
The login page is not showing correctly with the header (from master page).
And the setting on the web.config as below:
<authentication mode="Forms">
<forms loginUrl="Login.aspx" name=".ASPXFORMSAUTH">
</forms>
</authentication>
<authorization>
<deny users="?" />
</authorization>
Is there any reason why the header from masterpage can not be viewed from the login page?

Form1 is for the administrator. It has 5 fields. Field1 has a value for which the other values give details about it. This 5 fields are stored in a table. Form2 is for a user and its a data entry form. This forms has 12 fields. Each label in the form2 corresponds to the value of Field1 in form1. If suppose the admin fields 10 times the form1. The 10 labels of form2 are filled with values of field each time. The above is what I want to achieve. Also the two text box corresponding to the remaining two labels should be disabled for user.

I'm building a web page that is going to make extensive use of User Controls. Using "LoadControl" it will have one of about 20 different User Controls loaded at any one time. Each User Control is somewhat different, gathering different sorts of data.
I've already built the mechanism to load the User Control and pass strongly typed data to it. But now I'm tackling the part of returning the user data to the Parent Form. I can think of several possible approaches to take but wanted to reach out to the community to learn what the best practice for doing this is.

A requirement of a program I am making is that it can 'print' a given URL into a PDF - the server has a PDF printer installed (and is the default printer), so it's just a matter of printing the page programmaticly, and it seems the best way is to use the WebBrowser control - however, I am running into issues
[Code]....
With the above code, I get a script error 'dialogArguments.___IE_PrintType' is null or not an object' in shdoclc.dll/preview.dlg. If I have wb.Print() to somethign like wb.ShowSaveDialog() (or something like that, can't remember exactly), I notice the 'wb' object's document is a blank page, with just <html> tags and named 'about:blank'. But strangely, almost identical code (without the threading bit in the page_load method) works perfect in a normal Winforms based application.
