When you click on a button my program have to send a email where a report must be generated from table adapters from dataset. Now this report is not going to be displayed when the button is clicked, so it will be sent automatically by code which I have some part(see below). My questions are:
1. how can you generate or build a report without displaying it.
2.embeed this report or data collection from the table adapters as part of the body of the email
my email code so far is this:
mail.From = New MailAddress("qwerty@[URL]")
mail.To.Add(New MailAddress("qwerty@[URL]"))
mail.Subject = "test"
mail.Priority = MailPriority.Normal
Dim smpt As New SmtpClient
smpt.Host = [URL]
smpt.Port = 25
smpt.Credentials = New System.Net.NetworkCredential("qwerty@[URL]","****")) 'hehe not telling :P smpt.EnableSsl = True................
've created a Search partial view and it works, except for my view model. What i mean is, the partial view sends a string to my ActionResult Method, but only a string, that is not related to the view model that the partial view is built in. If i tell my ActionResult method to receive the view model in which the partial view is built in, it always tells me that i have null values. Here's my code This is my partial view:

Now here is my Model in my MoviesSearch view model:

Now the actual MoviesSearchViewModel

Inside my Search controller i have this

And then i have this:
I'm trying to pass a list of items from a LINQ query to a View, but I'm having trouble figuring out how to resolve a type issue. Here's the error:
The model item passed into the dictionary is of type 'System.Data.Linq.DataQuery`1[Project.Models.Diagnostic]' but this dictionary requires a model item of type 'Project.Models.Diagnostic'.
The issue seems to originate with this code from my Controller:
[Code]....
I tried changing the IQueryable<Diagnostic> to var and got the same error. Also played around with something like:
[Code]....
But then VS2008 says that diagnostics could never be null, and that's may not the best (or even valid) way to do it.
I have been trying to design a form, which uses a view model that contains an object array. I want to set up this form so that when the submit button is clicked, all the members of the array are updated. Here is my code:
The class definition of the array element:
[Code]....
The problem is that when I clicked the submit button, none of the luSubject objects in the array Subjects got updated. But if I set up some initial values for the members of the luSubject objects, for instance, set the Name field to be "Maths" in the constructor of luSubject class, then it got displayed on the text box when the form page was loaded. This suggests that this form could display the data in the array, but cannot update it.
I am trying to send json data from view to controller action. But the issue is the data is not populating in the action parameter List<Score>.
View Model:
public class Score
{
public int QuestionId { get; set; }
public int PrevAnswerId { get; set; }
public int CurrAnswerId { get; set; }
public string CurrAnswerName { get; set; }
}
Json Data look like:
[
{QuestionId:1, PrevAnswerId:3, CurrAnswerId:3, CurrAnswerName:'Known to Broker'},
{QuestionId:2, PrevAnswerId:7, CurrAnswerId:7, CurrAnswerName:'Completed'},
{QuestionId:3, PrevAnswerId:10, CurrAnswerId:10, CurrAnswerName:'Report'}
]
On window load, I will construct the Json object using "eval()" function and do some operation in the data before its save. On Save Click, I will call the action through the ajax call.
$.ajax({
url: url,
type: "GET",
dataType: 'json',
data: {score: ScoreJson},
contentType: "application/json; charset=utf-8",
success: function () {
alert("succes");
},
error: function () {
alert("error...");
} });
Action:
public ActionResult SaveScore(List<Score> score)
{
// do something...
}
But here score comming as collection of 3 elements with zero(for interger property)/null(for string property) values. When I checked in the request I found the data in "parama" property like.
"Score%5b0%5d%5bQuestionId%5d=1 &Score%5b0%5d%5bPrevAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerId%5d=3 &Score%5b0%5d%5bCurrAnswerName%5d=Known+to+broker&
Score%5b1%5d%5bQuestionId%5d=2 &Score%5b1%5d%5bPrevAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerId%5d=7 &Score%5b1%5d%5bCurrAnswerName%5d=Completed&
Score%5b2%5d%5bQuestionId%5d=3 &Score%5b2%5d%5bPrevAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerId%5d=10 &Score%5b2%5d%5bCurrAnswerName%5d=Travelers+Report&".
But I am not sure why it is not getting populated in the score list. One full day I spent for this issue but till now I didnt find the solution for this issue.
I'm using forms authentication in my C# based web site, with the authentication defined in web.config files in the various folders/sub-folders. I want to write a generic administration menu system, that lists all of the admin pages that the use is authorized to open. As I add pages, I want them to automatically show up in the menu. I need to obtain a list/collection of all pages that the active user is authorized to open. Is this possible in ASP.Net 3.5?
View 2 RepliesNote: I'm working with MVC3 RC and Razor views.I've got this model:

I want to have a strongly typed create view for this model, that allows you to insert 1 to many addresses and phone numbers as part of the view. Ideally, the Action is strongly typed as well:

What would this view look like to facilitate creating 1 to many Addresses and PhoneNumbers, as well as having the state re-created correctly if the ModelState fails when posting? I've tried a number of variations including EditorTemplates and can't figure out how to do this.

I have a list of objects that I want to bind to a gridview. Creating that list and binding it works fine for most of the public properties in that list.
There are some objects contained in each of those objects... for instance there is an Address object.
object.Address.Line1;
object.Address.Line2;
When I bind this to my gridview, I have no issues with stuff like object.DateRegistered, but how can I access things like object.Address.WhatEverProperty? I always get this error:
"A field or property with the name 'xxx.xxxx' was not found on the selected data source."
I want to know that how i use the collection class for storing some data and save it letter in the data base.
View 4 RepliesI have an ASP.NET app with lots of textboxes all over the page that need updating at various points through program execution.
These textboxes actually belong to a certain class, so for easy updating I thought I could create a Dictionary(Of string, object) and add the control.ID and the control to it and then for updating do something like this:
(in case of updating textbox.text):
[code]....
However the text property of the textbox does not actually get updated. I'm mainly trying to avoid having to manually do textbox.text = somestring for each one of my textboxes every time I have to update them.
I am using LINQ and sending a linq object to the view and trying to show it in a textbox like this
<%=Html.TextBox("petname",Model.PetName) %>
But I am getting error, how can I show (PetRecord.PetName) which is my linq entity
I know that if I have set a cookie on a previous request, it will show up in my Request.Cookies collection. I want to update my existing Cookie. Are the cookies from my Request.Cookies collection already copied to my Response.Cookies collection? Do I need to add a new cookie with the same key using Response.Cookies.Add(), or do I need to use Response.Cookies.Set()?
View 1 RepliesI'm using HttpModule to capture requests to the web server. Before processing the page I'd like to check the values contained in some keys of the Request.Form collection and according to some logic change if necessary. I'd like to do this when BeginRequest event is fired. The problem is that the Request.Form collection is readonly.

View 3 RepliesI would like to create a collection of key, value pairs in C# where the key is a property of an ASP.net control (e.g. ID) and the value is the value of that property. I would like to do this so I may later iterate through the collection and see if a given control has the properties in my collection (and the values of the properties in the control match the values defined in my collection). Any suggestions as to the best way to do this? Pseudo-code example:
Properties[] = new Properties[] {new Property(){name="ID",value="TestControl1"}, new Property(){name = "Text",value="Type text here"}}
private bool controlContainsProperties(Control control){
foreach(Property Property in Properties[])
{
if((control does not contain property) || (control property value != Property.Value))
return false;
}
return true;
}
I got this situation where I got a ICollection and I need to see if there is a object containing a title in it. If the title don't exist i can go ahead and shave the new object.
How can i do this? note i am already working with a for each loop on the titles..

I have a form that contains an asp:Menu control. One of the menu items is "Login" item. The way I want my application to work is when user gets to the main page, I want all the menuItems to be disabled except for the "Login" item which forces the user to login into the system. Once logged in, all the other Menu Items will become enabled.
My problem is, in my Master Page code-behind logic, I have a routine that disables all the menu items except the "Login" item. What I want to do is also change the backcolor property for each of the disabled menu items. Here is my code below:
Code:
Private Sub DisableMenu()
Try
[code]....
The Red highlighted lines of code will do what I want but it also changes the color of the "Login" menu item which I don't want.
how do I bind a DataGrid to a collection? (e.g : List ). i used this :
Datagrid dg = new Datagrid();
dg.DataSource = myCollection;
dg.DataBind();
but after this, the Datagrid still doesn't display the data from the collection.
I've a collection defined in .NET. The collection contains a few hundred items.
example of the object in collection:
Tag.Name = "Tag1"
Tag.ID = "2"
Tag.Location = "Home"
and so on (a few hundred items).
I've a stored procedure to insert that data into the datatable. The logic in the sp checks first if the tag name already exists in the table.
If not, then insert.
Now I can use a loop to insert the data, but is there another way to do the same more efficient ?

I would like to cache a collection in the viewstate, but I wonder if there is a better way to add an item to this collection!
private List<MyClass> CachedItems

get { return (List<MyClass>)ViewState["CachedItems"]; }

}
private void AddToCachedItems(MyClass item)
{
CachedItems = CachedItems.Concat(new[] { item }).ToList();
}
