I have a gridview with entity frame work datasource. When editing or deleting I get Store update, insert or delete statement affected an unexpected number of rows(0). I selected * from the datasource. I made a template field to show the posts. There is a PostId in the framework. I am guessing that the PostID is not bound to the gridview the problem and the fix?

can we say like "Entity frame work make use of linq to entities"?
what is the relation between linq qnd entity frame work?

I have a user control, named productslist.ascx. On pruductslist.ascx, I am using Entity Datasource and a QUERY EXTENDER and LISTview. I have a page Defualt.aspx. On Defualt.aspx, I have a TEXTBOX with a SUBMIT button for searching the site. Everthing works fine so far, AS LONG as the results of the Search is posted back to Default.aspx. What I want is for the results of the search to be posted on a different page.
So I created a new page, Results.aspx and set the postback url to it.
What I want is that when a user clicks the Submit button, after entering a search string, the text the entered is used to execute the query on Productslist.ascx and the results displayed on RESULTS.ASPX. Again, everything works fine as long as the results are posted on same page hosting the usercontrol, BUT I want the postback url to be a different page. I am coding in VB and VS 2010.

View 3 RepliesI'm using a "frame" layout similar to the one in this excellent answer: a div #top at the top of the page, a div#left on the left, and a div #main with the main content. The #top and #left divs contain navigation menus.Now I want to use a popup div using the AjaxControlToolkit ModalPopupExtender inside the content (#main) div.This works fine on IE8 (where #top, #left, #main all have position:fixed), but when I run it on IE6, the modal background only covers the #main div - I need it to cover the whole of the page including the #top and #left navigation divs.

I am new to Entity Framework and working my way through it little by little. I think I have it figured out on how to get data into and out of 1 table at a time now the challenge is 2 tables into a gridview.
I have a user table that has a list of threads that a user can mark to track. Easy enough. Assign the userid number & threadid to a table with a push button while the user is logged in and viewing any of the posts that are on that thread. The new challange is to get only the posts that the user has marked to track. SQL easy. Entity not sure what to do.
If I make a view or stored procedure and add it to the database that would be an extra step. To join the 2 tables as in sql Select posts from posts where track.userid = @userid join track on post.userid=track.userid Seems Entity was made to avoid this type of thing. Than once the data is gathered I need to bind it to a gridview()
I got a gridview to display the data from the database properly but when I go edit. it give me an error. I searched and change ConflictDetection=CompareAllValues to OverwriteChanges
The error goes away. However the database is still doesn't update. Does anyone had to tweak the gridview function to make it works. Maybe I did something wrong.
I have this situation where I have three pages:
The first page, default.htm, is a frameset page that uses the other two pages.
The second page, casemenu.aspx, is a form that contains an object we call "PopupManager": It has an element <xxx:PopupManager runat="server"/>. This object is dependent on the standard ScriptManager, which requires a form.
The third page, header.aspx, contains three links. Each link calls a JScript function that in turn calls a function on the Popup Manager. It makes the call to the popup manager with an expression like 'top.frames.casemenu._PopupManager'.
Now, the problem I have is that I have to change default.htm to be a normal page containing an iframe, which will refer to a new page, container.aspx, which has the original frameset. When I do that, I can no longer access the PopupManager the same way ('top.frames.casemenu._PopupManager' no longer works.)
I would like some way to refer to the PopupManager relative to header.aspx, something like "self.parent.frames.casemenu._PopupManager", but that doesn't work.
if LINQ to Entity queries the EDMX class or its .CSDL or SSDL XML on its way to getting data from the RDBMS?

View 1 RepliesMVCThe generated ADO.NET Entity Data Model loses ordinal positions of columns and reorders Entity Set column names alphabetically. This causes the columns in a new MVC VIEW to appear alphabetically and needs to be reordered by hand. I am using MySQL Database.

In my program, I want to update a record of user table, so I use the code below to do this.
In this function I send changed user info and then overwrite the information with the current user information.
After I run objUser = _user; and then call objContext.SaveChanges(); to save the changes.
But when I do this, the changes are not persisted to the database. I use this code for another programs but in this case the code does not work!
public void Update(tbLiUser _user)
{
LinkContext objContext = this.Context;
tbLiUser objUser = objContext.tbLiUsers.First(u => u.tluId == _user.tluId);
objContext.Attach(objUser);
objUser = _user;
objContext.SaveChanges();
}
