Sum''ing up time stamps across multiple lines.

I have GridView that is bound to an ObjectDataSource and within that GridView I have CheckBox, DropDownList, TextBox and Label controls.  All the controls except the CheckBoxs are working like a champ or normal display and Delete (Insert is handled outside the GridView, it works also). 

The CheckBox values are passed into the update method for the ObjectDataSource as type byte.  Without doing any custom coding the CheckBoxs were always unchecked (regardless of the data being 1 or 0)  and when I edit a row in the GridView and saved the values the CheckBox controls would always be 0 even if the check boxes where checked. 

After searching web I found a suggestion to change the binding on the CheckBox controls from, Bind("Monday") to this, CheckUncheck(DataBinder.Eval(Container.DataItem, "Monday")) with CheckUncheck being a method to make 0 or null = false and 1 = true.  This seemed to the do the trick and it set the CheckBoxs correctly in the DataGrid, I was giving myself high-fives, until. I tried to update a row. 

When doing the update, as with my first attempt, it would always set the CheckBox values to 0, thus ignoring the checked property of the CheckBox.  So I search the web again and found a suggestion to handle the update manually, due to the binding being one way. So I created a myUnhappyGrid_RowUpdating event handler and changed all the columns in the GridView to template so I could do the old school .FindControl on them and grab the values.  Once I was able to grab the values from the row to be updated I added them to the ObjectDataSource .UpdateParameters and called ObjectDataSource.Update() and it worked, kind of. 

Now came the next trial, it did the update into the database just fine and I was happy, until..  I finished stepping though the code.  As I stepped through the code the update on the ObjectDataSource got called two more times, thus undoing what I had just spent hours fixing.

First, is the road traveled the right way to do it?

Second, if I am on the correct road how can I suppress the additional two updates that follow my manual .update call on the ObjectDataSource?

Please help!

Hi All,

I am new to MVC. I am trying to write a simple web app - for learning purposes only, that allows multiple users to log in and enter their top 10 favorite movies. Each user can only see and edit their own list. The can have no knowledge of the other users or their lists.

In regular ASP.Net I would do somthing like a session variable to store the user id so I could use it to test against the database and return that users information. I as I understand it that is not the way things are done in MVC. My question is how would I do this in MVC?

thanks for any tips or advice!

I'm using VS2010 and I'm trying to follow along with these videos: http://www.asp.net/general/videos and the guy in the video is using Visual Web Developer Express and when he creates a new website it's all nice and simple with a bare bones Default webpage and that's cool. Well, me in my Visual Studio 2010 when I create a new project I get this elaborate "My ASP.NET Application" page with an About page and a Login page and CSS and Jquery and it's just too, too much. Now, of course I could just create an empty ASP.NET application, but that goes too far the other way; I have to start from scratch and add the default page myself and try to reproduce exactly what the code in the video looks like and I can't really see the screen that well. Is there any way I could change my default template to what the gentleman in the video uses?

I'm trying to use the ListBox html helper in a simple form.

verhuurPrijzenLst is a simple list that gets put into the ListBox, I think I need "MultiSelectList", but I cannot use it (MVC framework needed)?

I don't know exactly how to do that ( bin folder and @inherits ? )

So it's nice to have a helper at hand, but if you cannot use it properly without using the MVC framework, that is a pity.

   List<SelectListItem> verhuurPrijzenLst = new List<SelectListItem>();
   foreach (string dataLine in verhuurPrijzen) {
        var verhuurPrijslijn = dataLine.Split(delimiterChar)[0].AsDateTime().ToString("dd MMMM") + " - " + dataLine.Split(delimiterChar)[0].AsDateTime().AddDays(7).ToString("dd MMMM") + " ? " + dataLine.Split(delimiterChar)[1] + ",00";
        var selecteer = false;
        if(Request["Huurperiode"] != null)
        {
            if(Request["Huurperiode"].Contains(verhuurPrijslijn))
            {
                selecteer = true;
            }
        }
        verhuurPrijzenLst.Add(new SelectListItem { Text = verhuurPrijslijn, Selected = selecteer });
    }
    @Html.ListBox("Huurperiode",verhuurPrijzenLst,new {size="15", multiple="multiple"});
