i have a webForm which can update dataRow like this :
[Code]....
everything is ok, but my database was not update after clicking sumbit button. in debug mode i found a big problem! controls does not have new value and pass old values to '_row' object.where is my problem and how to solve it ?
I'm coding my first VB web application, which allows a user to input an order number and pull up invoice and shipping data linkd to that order number.
I have the first bit down and working, where the existing data in the database is displayed in the GridViews. One of the GridViews is set up to allow data editing, and I have syntax set to make the row editable, but I'm struggling with getting the "Update" link/functionality to work. I want to assign the values in each cell to an object (ie. 'dgInvNumber' for Invoice Number), but everything I've tried (been doing a ton of Google searching for help, but no luck yet) keeps giving me an "Object reference not set
to an instance of an object" error when I click the Update link for the row of data being edited.
At this point, I don't know what syntax to use to get the edited values out of the GridView row and assigned to objects for each cell (I have a total of 10 cells that can be edited in a row).
For background info, the GridView is set up with Bound Fields. I'm using Visual Studio 2005. Alot of places I've looked talk about TextBox controls and using FindControl. Also seen some places talk about DataBoundLiteral Controls. I tried the latter with no luck (still getting error). For TextBox controls, I don't understand how to use that part, since it mentions referencing the TextBox controls declared in the EditItemTemplates of the TemplateField column fields in the GridView control. But I didn't set up anything in the EditItemTemplates (that I know of).
I have two grid view controls one is temporary and another is simple grid view control.in the simple grid view control it includes the edit button on its command name edit i want to edit this grid and also to show values in the temporary grid. How it can be possible?
View 1 Repliesusing the latest bits for MVC 3 i'm looking at the code for a Controller (Northwind products), specifically my 'Edit'Action.
there are two methods, one for diplaying the item to edit, and one for posting back changes made on the UI.
My question is : how do i get a reference to the currently edited product. The method takes 2 arguments; the id of the product and a formcollection which is a dictionarly of product proerties by the looks of it. mvc 2 had slightly differentt arguments compared to mvc 3 beta.

Creating a system with web front end and SQL backend (microsoft obviously). I have tried using the asp.netsqlprovider but i can;t as i am only allowed one database on the server, so i then tried to update my current database with the triggers to input the schema into the already existing database.Next step i create my own table with two simple fields of username and password and try and authenticate that way, i can't get that to work either.
I ahve limited permissions on the network as i am a University Student. I really don't know what to do. Never had to create a log on system before and i thought it would be far simpler than this. I ahve used Microsoft's sqlprovider schema before and it worked fine. I have also authenticated via IIS and AD too before. I can't do any of those two in this instance it seems.I need an alternative for logging in users, if needs be in can be crude. I also still need to have some kind of two different views too for logged in users and not logged in users, but that can change if needs must.Don't let me down people, haha. Think this posts in the correct place, i could not find another one i thought could be more relevant.

{
//Create a connection to the database
MySqlConnection conn = new MySqlConnection("Database=kid07025;Data Source=195.178.228.254;User Id=kid07025;Password=********");
//open the connection
conn.Open();
//MySQL Query which updates the row where Anvandarnamn = Anvandarnamn (recieved from a cookie)
MySqlCommand cmd = new MySqlCommand("UPDATE personer SET Information=?Information,Fnamn=?Fnamn,Enamn=?Enamn,Personnr=?Personnr,Adress=?Adress,Postnr=?Postnr,Ort=?Ort WHERE Anvandarnamn=?Anvandarnamn", conn);
// Update with new text
cmd.Parameters.AddWithValue("?Anvandarnamn", Request.Cookies["Anvandarnamn"].Value);
cmd.Parameters.AddWithValue("?Information", TextBox1.Text);
cmd.Parameters.AddWithValue("?Fnamn", TextBox2.Text);
cmd.Parameters.AddWithValue("?Enamn", TextBox3.Text);
cmd.Parameters.AddWithValue("?Personnr",TextBox4.Text);
cmd.Parameters.AddWithValue("?Adress", TextBox5.Text);
cmd.Parameters.AddWithValue("?Postnr", TextBox6.Text);
cmd.Parameters.AddWithValue("?Ort", TextBox7.Text);
cmd.ExecuteReader();
conn.Close();
RefreshProfile();
}
I don't know what I am doing wrong here, but the database doesn't get updated when I press the button.

In VWD, we can customize-edit-command to your heart's content. But there is none for what I used to get in NetBeans or Eclipse: go to the last edited position (after 5 minutes of search for the correct spelling of some name in the page).I know there is Navigate Back, but I often need to do click [Navigate Back] 10 times to get to 'last edited line'.
It would be nice if I can navigate through the 'green bars' (Yes, it is very difficult to find out what are green bars, once you found out, you want to be able to visit each of these using next or prev).
Also where is the documentation or help ofr each of the some 50 edit commands such as 'go to Reference'.
I am binding the ReorderList in my code behind file. I am not using a DataSource Control like SQLDataSource etc. How will I capture the values edited, in my ReorderList1_UpdateCommand(). In GridView we can use something like
