I am trying here to find a simple solution to bind an array of elements to a model using the MVC model binder. If I use the @Html.Checkbox helper now, it will generate me something like this :

In the controller I try to bind it with the UpdateModel()

I have a BLL where in I am getting all the data from a table. Now I want to populate a dropdown with one of the field in this BLL.
ddlstatus1.SelectedValue = dt.Rows(0).Item("StatusCode") and this is not working.
I tried ddlstatus1.SelectedIndex = dt.Rows(0).Item("StatusCode") too but this is throwing an error that string cannot be converted to Integer.
I'm binding a Dictionary to a drop down list.
Say for example I have the following items in dictionary:
{"Test1", 123}, {"Test2", 321}
I'd like the drop down text to take the following format:
Test1 - Count: 123
Test2 - Count: 321
I was going along the following path with no luck:
MyDropDown.DataTextFormatString = string.Format("{0} - Count: {1}", Key, Value);
How would I re-code the datagrid below so it displays as a drop down list? The data I want to display in the drop down list is ID="dgvFitters".Also, is it possible to display the data in a datagrid and in a drop down list simultaneously?

I'm trying to display a list of Excel files that are stored in multiple folders in adatagrid but the .GetFiles part of the routine in my loop only gets the very last excel file rather than all that meet the criteria. Below is the code I've been working on for several days. This is the first time I have tried to use a "For next loop," and I am having much trouble with this. Using the same loop code posted I was able to verify that the loop was working by appending some text into a temporary label.

This is my first post as a newbie to asp.net.
I am in the process of creating a "news system", you can add, edit and delete news. The news items can be entered into the SQL database and you select a category where you want the news item to go into.
What I want is when someone comes to the "Edit" screen, they have a drop down list and what that does is allows you to select a category for you to edit news items from, so rather than at present having the "Edit" page display all the news items, I want people to be able to choose a category that they can edit news items in.
So far my edit page has a datagrid with the following code:

I am looking here to find a quick and easy way to bind a list of checkbox list items when the postback occurs in the model. Apparently the common way to do it now seems to do it like this form.GetValues("checkboxList")[0].Contains("true"); It seems painfull and not exactly safe. Is there a way to bind a list of checkbox (that are created with or without an helper in the view) or even an array of data for that matters during the UpdateModel(myViewModel, form.ToValueProvider()); phase which would populate an IList<string> or string[] inside of the model ?
