Web Forms :: DropDownList LINQ No Default Value?
Jun 1, 2010I have a dropdownlist that is being populated using linq. The code for linq is below
[Code]....
When the page is viewed the dropdownlist show the following;towels, shoes, etc. What I would like is the default item to be nothing. That is when the page is viewed then the drop down list should show something like this "select category". Right now it is starting by showing towels, which is quite irritating, since if I want to see towels I first have to select something else and then go back and select it!

DataSource Controls :: LINQ Load Collection To Populate Dropdownlist?
Apr 5, 2010I have a partial class extending my Entity Model. I'd like to write a method that returns a collection of types from my entity framework model. For example, I'd like to get all the states to populate a drop down list. So I've written a method called getallstates(), similar to the example below:
[Code]....
I tried returning a list of Objects, and a list of states to my calling method to be used to bind to a drop down list. However I get an error that:
Server Error in Application. Unable to cast object of type 'System.Data.Objects.ObjectQuery to type 'System.Collections.Generic.List`1[System.Object]'.
What should my return type be for this function?

Filling The Rest Of The Page With CSS?
Feb 22, 2010I have three Divs on the page and they are absolute positioned. Lets call them leftDiv,middleDiv,rightDiv and middleDiv width is 900px which is okay but the left and right divs should fill the remaining the left and right parts respectively no matter what screen size is.
The reason why I use absolute positioning is because it is the only way to use height:100% to fill the page.
So how can I fill the remaining parts?
Of course these divs separate page into three pieces according to their names imply.

Forms Data Controls :: Showing Linq Result Values Inside Dropdownlist Inside Listview
Jun 22, 2010I have a listview that is showing its result by using a linq query. The linq query goes like this.
[Code]....
* db.Varer: Varer is a table that contains basic product information like proudct name, product nr. etc. ** a.fk_kategori_id == CatParamId : I'm just saying limit the result according to the Category ID (a.fk_kategori_id). The category id is coming from a dropdownlist (CatParamID) *** Join: Besides the Varer (Product) table I also have another table, Sizes. This Sizes table contains 6 columns (ID_Sizes (int) primary key and the columns: OneSize, S, M, L, XL, XXL all are bit (true or false)). There is a relationship between Varer table and Sizes table. It says that I can only insert a value into the "fk_sizes_id - column" of varer table if that value already exists as primary key within the Sizes table. **** I'm starting by picking basic product values like productId, ProductName etc from the Varer (a) table ***** Then I'm picking the corresponding Sizes values (onesize, s, m, ...) from the Sizes table. Now within my ListView I'm showing the above result by using Eval, like this.
[Code]....
And this works perfectly, but now comes the thing that is causing me trouble. I have the below drop down list (still within the ListView ItemTemplate):

I want this drop down list to be populated with only those of the "linq query's Sizes table result" that are true. By "Sizes table result" I mean these

Caching When Filling Panels With Content?
Jan 7, 2010I'm creating a group of surveys that query Salesforce ([URL] CRM) to generate survey questions dynamically.
The survey layouts are determined by a record type that gets passed in the QueryString. The page queries Salesforce and aggregates the questions/fields it should be using. Then it creates questions and adds them to a panel.
When I open one survey, things look great, and they work as designed. But on opening a separate survey, of a different type, the questions from the first survey are still in the questions panel, as if they are cached somewhere.
To see what I mean, open "Survey 1". Then open "Survey 2" in a new tab. Now re-open "Survey 1", but this time do it in a new tab. Compare the first "Survey 1" to the second "Survey 1", and you'll see that the second "Survey 1" has the questions from "Survey 2" added into it.
Is there something - or a way that - I should be clearing variables, public variables, sessions, or page/panel caches on every page load?
I define the array where the fields/questions are aggregated like this:
ASP Code:
public partial class _Default : System.Web.UI.Page
{
private static ArrayList field_names_use = new ArrayList { };
