I'm trying to add Div Objects to an array and trying to access them later when I call my loadViews function. All of my alerts fire, in the proper order, but the array m_Divs is always of length 0.
I'm re-registering the script each time on Page_Load, due to it throwing an "Error: Object expected" after each page_load when trying to call the javascript if I don't.
.JS file.

I have a gridview control that displays expenses claims received from clients. I have a template field that contains a checkbox - if this is ticked, a value from the gridview is added to a variable and this is outputted to a label control.
What I then want to do is to update the database according to which row has been ticked. I have so far the following code that adds each value to an array, which I was then hoping to access in the sql query i.e. Update table set value = value where id = (id's added to array)..
Code as follows - so far I'm just displaying the count of values in the array to make sure they are actually being added:

My brain doesn't seem to be working today. I googled around for this and just couldn't find it, which seems kind of strange since this is such a basic question that I can typically find out very quickly.
I'm trying to create an array of DateTime objects. I can't use a List.

However, I get an error, stating use of unassigned local variable.
In the project I'm working on I have got a list List<Item> with objects that Is saved in a session. Session.Add("SessionName", List);
In the Controller I build a viewModel with the data from this session
[Code]....
and in my View I loop trough the list of Items and make a form for all of them to be able to remove the item.
[Code]....
When the post from the submit button is handeld the item is removed from the array and post back exactly the same viewModel (with 1 item less in the itemList).
return View("view.ascx", viewModel);
When the post is handled and the view has reloaded the value's of the html.Hidden and Html.Textbox are the value's of the removed item. The value of the html.Encode is the correct value. When i reload the page the correct values are in the fields. Both times i build the viewModel the exact same way.
Assume the JSON returned is
{"2010143545":{"info":[1,"soccer"]},
"2010143547":{"info":[0,"Basketball"]}
}
How do I use JQuery to render the array on ASP.NET page? More precisely, what kind of HTML template do I need to set to stuff the JSON with JQuey?
Iam getting an array of list from database to client side(javascript array). Now my aim to place those values in a div one by one and that div should attach to the textbox similar to Autocomplete extender.
View 4 RepliesIn ASP.NET I have a form that has a Textbox named txtOutput and a button. In the main file.aspx.vb I can call a function from the button handler and in that function I can have
txtOutput.Text = "Some Message"
with no problem. I have a bunch of functions in several other classes. For instance I have a class named AbleCommerce that does some database functions. These functions are called from my main class. In those functions, however, I have no visibility of txtOutput. All of my classes are, unfortunately, in the default namespace which I understand is not optimal but didn't seem to impact this issue.
I know this is an easy one I've just not understood properly but it has me stumped. My gut says that I probably need to pass the Textbox object to my "other class" but can't for the life of me figure how.
I am using MVC 2. I have a master page and a view that uses this master page. I have to use a javascript file for this view only, and not for the other views. What is the best way to add a javascript file to this view? What I currently did was to add the javascript file at the top in my content tag. Is this the best way to do it? I did it as follows:
<asp:Content ID="cntMain" ContentPlaceHolderID="cphMain" runat="server">
<script src="../../Scripts/myjs.js" type="text/javascript"></script>
</asp:Content>
The content place holder for this content tag in my master page is in a div, so it is complaining that a script tag can not be in a div, and underlines it in green. So I am assuming that there is another decent way of doing this?
I have a new blogengine site up and want to set up syntax highlighting. The problem is that I have a few files (javascript and css) that I need to add the the head of the page, but there is no one page or masterpage. where to write out these references so they will show up on all pages?
View 4 RepliesI have a single master page in my application. It has a Label control for displaying Error Messages. I want to be able to access this Label control from any child page or Class module within the application. How do I reference this label from a Class module. I simply wish to use a Try Catch construct in the Class Module and reference the MP Label in the Catch segment.

I've got a website and we just had a huge jump in traffic. Now all of the sudden we're getting sql parameter errors left and right. We switched to a new sql server a few weeks ago and everything has been fine but the added traffic seems to be breaking us.
I have a data access class that is called when each user trys to logon. It runs through several tasks before finally updating the users last login date and forwarding them to the administration section.
What I'm seeing from the trace logs suggests that when I'm logging in the first several tasks are using my data (lets say user=birk pass=word). But at some point the accessor class starts sending over the data from someone else who's trying to login (lets say user=abcxyz)
Every connection we make to the server is closed when we're finished with it. I'm nulling out all of the accessor objects when I'm finished with them. But somehow different user data from different sessions are making their way into other peoples instances of the object.
I'm not using session/application/cache/viewstate to store the objects so I'm not really seeing how they could edit eachother... Its just really weird and I'm not sure how to even go about researching the problem.
This is roughly the accessor class... I trimmed out some of the parts that weren't reliant to the issue

how to pass a C# ASP.NET array to a Javascript array? Sample code will also be nice.
Let's say for simplicity that in my aspx.cs file I declare:

We have a pretty big database with hundreeds of procedures, triggers, functions, views, etc. Now we are in the process of moving from VSS where SQL Objects were not added to the TFS. Is there an efficient way to add all the SQL Server objects to the TFS?
View 1 RepliesI have the following tables:
Campaigns (CampaignId, CampaignName, etc)
Urls(UrlId, CampaignId, UrlText)
I have a relationship setup between Campaigns table and Urls (FK_Url_Campaign) everything works fine when I try to add a new campaign but when I try to insert a new Url I get:
Entities in 'DatabaseEntity.Url' participate in the 'FK_Url_Campaign' relationship. 0 related 'Campaign' were found. 1 'Campaign' is expected.
This is my code:
// INSERT
public int Insert()
{
Url dbUrl = new Url();
dbUrl.CampaignId = (int)CampaignId;
dbUrl.Url1 = (string)Url;
context.AddToUrl(dbUrl);
context.SaveChanges();
return (int)dbUrl.UrlId;
}
Pretty much i want update/add new campaign and then I call Insert for Url. how would i go about doing this?

I am trying to create a view that would contain a set of fields that tie to an AgencyAddress object, an add button, and under those fields, a list of AgencyAddress that would show addresses that were added. My view works, and the fields are properly bound, however I can't seem to get the list to maintain previously added addresses.
What happens, is that every time the Add button is pressed, the List is re-created (or VS yells at me to create a new instance) and only contains one record. I'm sure I'm missing something simple, but I can't figure out how to pass the list back and forth and be able to add to it. Two weeks on my own is where I draw the line! My ViewModel:

I'm playing around with a asp.net page that's using the IScriptControl interface to pass data from the code-behind to the custom javascript object running on the browser.I'm passing a number of properties via IScriptControl.GetScriptDescriptors(), and they're all working fine, except for one.That one is a class derived from System.Collections.Generic.Dictionary<>. And even that one has been working for me, so long as the elements in the collection were scalars - ints, doubles, and strings. But when I tried to pass a member of a class, it showed up as a null object in the javascript. The class in question is marked [Serializable]. I changed it to a struct, and got the same behavior.It looks as if the serializer used in IScriptControl does a shallow copy.
