I have a list of objects that have values to them. Specifically one of these values if a boolean (isAbnormal) to determine whether or not the value itself is classified by our application logic as "Abnormal" or not.
I have composed a list of a mixture of abnormal/not abnormal items. I want and need to remove items from this list that aren't clsasified as being abnormal (in programming logic, isAbnormal will be false)
I have tried several ways and can think of some dirty/ugly ways to get it, but there has to be something better:
I am trying to get a simple multi-page program to run correctly. I have everything set up, except for the "remove" function. When I try to remove an item from the list box nothing happens. Insted of trying to explain it I will show you the code...
Another niggling issule. I am trying to remove all the databound items from my listview but it doesn't work. I am trying to remove the items as i have used the delete command button (alongside with the updateand edit)
using asp.net 4 and vs 2010 I have a listview that displays data from a database. I have to configure it to display all column data where present, however, not all columns have data, with the result that blank spaces get rendered where this data would normally be displayed.
The code:
[Code]....
So, for example, some of the individuals that exist in this table might no longer be associated with a specific department, institution or have data in the "Address2" column.
So I have a number of dropdown select list controls populated as part of a repeater. They might contain overlapping data, meaning that the first d d list control will have selections:
a b c
Second one:
c d e
Third one:
d e h
and so on.
So what I would like to do is to srart removing the duplicate items from the reset of drop down controls once the user starts selecting those. I intend to use jQuery for this.
How do you go about removing multiple items from a array list?
I'm using the RemoveAt() method to remove but doing that resets the ArrayList's index which cause me problems if the user selects to remove 1 & 3 out of a 3 list array since once it removes 0 the array list now just has 0 & 1.
I have three listboxes, lst, lstA, and lstB, in which lstA is an instance of lst. The problem I have is that whenever I remove an item from lst, the same item in lstA is also removed. I have tried assigning a different ID to lstA to no avail. see my code below:
i've a songs website, where i'm adding items to cart for users who are logged in, but when a song is deleted from the website the users still have the cart info still intact, i'd like the songs in the cart also too be deleted when the song from the website is gone, how may i accomplish this ?
I'm creating a composite control for a DropDownList (that also includes a Label). The idea being that I can use my control like a dropdown list, but also have it toss a Label onto the page in front of the DDL.
I have this working perfectly for TextBoxes, but am struggling with the DDL because of the Collection (or Datasource) component to populate the DDL. Basically I want to be able to do something like this: <ecc:MyDropDownList ID="AnimalType" runat="server" LabelText="this is what will be in the label"> <asp:ListItem Text="dog" Value="dog" /> <asp:ListItem Text="cat" Value="cat" /> </ecc:MyDropDownList>
The problem is, I'm not extending the DropDownList class for my control, so I can't simply work it with that magic. I need some pointers to figure out how I can turn my control (MyDropDownList), which is currently just a System.Web.UI.UserControl, into something that will accept List items within the tag and ideally, I'd like to be able to plug it into a datasource (the same functions that the regular DDL offers).
I tried with no luck just extending the regular DDL, but couldn't get the Label component to fly with it.
I've been at this same question in different forms now for a while (see e.g. Entity Framework and MVC 3: The relationship could not be changed because one or more of the foreign-key properties is non-nullable. ), and it's still bugging me, so I thought I'd put it a little more generically:
You have an entity object (using Entity Framework), say User. The User has some simple properties such as FirstName, LastName, etc. But it also has some object property lists, take the proverbial example Emails, to make this simple. Email is often designed as a list of objects so that you can add to that object properties like Address and Type (Home, Work, etc). I'm using this as an example to keep it generic, but it could be anything, the point is, you want the user to be able to add an arbitrary number of these items. You should also be able to delete items (old address, or whatever).
Now, in a normal web page you would expect to be able to add these items in the same View. But MVC as it seems designed only makes it easy to do this if you call up an entirely new View just to add the address. (In the template for an Index View you get the "Create New" link e.g.).
I've come across a couple of examples that do something close to what I mean here:
[URL]
and
[URL]
The problem is, although the sample projects on these sites work fine, with mock model objects, and simply lists (not an object with a child list), it's a different thing if you actually want to do something with the posted information - in my case save to database through the Entity Framework model. To adapt these cases to that, all of a sudden I'm in a maze of intricate and definitely not DRY code... Juggling objects with AutoMapper and whatnot, and the Entity Framework won't let you save and so on (see above link if you're interested in the details).
What I want to get at is, is it really possible that this is such an uncommon thing to want to do? Update a child collection in the same View as the parent object (such as the email addresses in this case)? It seems to me it can't be uncommon at all, and there must be a standard way of handling this sort of scenario, and I'm just missing it (and no one here so far has been able to point me to a straighforward solution, perhaps because I made it too abstract with my own application examples).
I'm relativley new to ASP and am using VB for the coding. I have a page that has a few fields on it, one being a drop down list that get's populated from a SQL Server.
I used the GUI to generate this form (see below), the connectionstring:Prod1ConnectionString that is stored in the web config file is hard coded. I want to change that I use the connection string that is passed as a Session parameter. I've been looking for hours for an example of how to remove the connectionstring from the web code and place the proper code in code behind script on the load_page event.
i have six items in my select in which 4 of them are add,edit ,delete view, it is multiselect list, i don't want the user to remove the these 4 items , apart from that they can remove any item. how will i do that? it is not happening in the above code
I need to pass a random number from 1 to 100 from the client to a webservice, and then the webservice will subtract this number from the list of 100 numbers (say 1-100). Then, in the next call, the next random number will be subtracted from the rest 99 numbers and so on.
I need this to be done with AJAX. I don't know where the Array list should be held in the first place (would it be in the web service or in the code behind? ), and how this can be done?
I'm designing my own custom control that contains a .NET dropdownlist. What I'm wondering is if it is possible to populate my dropdownlist with listitems placed in a placeholder? For example:
This doesn't work because the DropDownList control only allows ListItems as child controls. But, I want to do something similar to this so when the user includes my control on a page, they can do something like this:
Is it possible to select values from a List, where the items contain in a different list aswell?for example;
[Code]....
What I need are all the items from the first list "Items", where the string contains something from the second list "List".So I need something which returns the first 3 items (which contain the term "Item") from the first list.
Long ago, I created an ASPNET user for development use.However, every time I boot up my dev system, I'm presented with a user login for ASPNET, among others.I don't want to remove ASPNET; I need it for dev work.But how do I keep it from appearing among the list of User Logins available at boot-up?
