GenericCollection Strongly Typed on Retreval

Posted By:      Posted Date: April 14, 2011    Points: 0   Category :WPF
 

When using Generics i keep hitting a situation where i'd like to be able to collectively store generic classes with out reference to the typed constraints applied to generics at the point of storing

 

The solution that seems feasible to me would be a Collection<TGeneric<>>:KeyedCollection<typeof(TType), TGeneric<TType>> where TGeneric would be the Generic class and TType would be the type applied to it

so as an example you have some generic class CLASS<T>{}

you create

GenericCollection<CLASS<>> col

then

Col.Add(new CLASS<int>)

Col.Add(new CLASS<double>)

Col.Add(new CLASS<string>)

then if you do

Col[int]

you would get back the CLASS<int> object in a type safe format

 

the question is is this possible under the CLR with out using refection (as far as I'm aware not, but i may be wrong)

if so how would you do it and if not does anyone else think it would be a valid and useful addition

How to create strongly typed datasets with access parameter queries

  

Hi

How can you create strongly typed datasets using an access database against access select statements that use parameters?

The problem is VS.Net doesn't allow select queries with parameters to be dragged onto a form, it only allows access queries without parameters!

I also tried the dataadapter wizard, but again it only allows me to select queries without parameters?

Many thanks in advance

 


Strongly Typed DataSet Cleanup

  
Hey all, I've looked around and I can't seem to find a good answer on this. Is there any cleanup needed on a strongly typed dataSet? I'm using DataSets as my DAL but I don't really have a BLL. I'm handling this in my code behind like this: Private PunchAdapter As New PunchDSTableAdapters.PUNCHIMPORTTableAdapter Dim LastPunch As String = PunchAdapter.GetLastPunch(PersonNUM) PunchAdapter.InsertPunch(PunchID, ReqCode, PersonNUM, txtDate.Text, txtTime.Text) I'm assuming it handles the opening and closing of the connetion? The adapter has a dispose method. Should I be using this? Is there any cleanup necessary or does the partial class (that inherits system.data.dataset) handle all of this? Thanks!

Problem with SCOPE_IDENTITY in strongly typed datasets

  

Hi,

I am developing an ASP.NET site and I am using strongly typed datasets and I am generating them automatically in Visual Studio 2008. I have been using TransactionScope to be able to use several table adapters from different datasets and update them in one transaction. When I create a new row, I use the update method in the table adapter to create new posts. The update method takes a dataset, datatable or a row as argument making them very easy to work with. After I have updated a row, I have generated a ExecuteScalarGetIdValue() call to get the latest inserted ID value. I use "SELECT SCOPE_IDENTITY" and it gives me an exception. When I try the query builder this SELECT SCOPE_IDENTITY is returning NULL. When I ask it in SQL Management Studio SQL Query window it returns a correct value. How can I get the correct value from the table adapter?
      {

      ...
        this._tableAdapter.Update(dataTable); 
       
        id = this._event.ExecuteScalarGetIdValue();

       ...

        scope.Complete();
      }

      return true;
    }

Strongly typed view validation

  

I have a strongly typed view with my model being entity framework.  In my controller I check for ModelState.IsValid.  When I submit my form without a value for a column that does not allow nulls it crashes before it gets to the ModelState.IsValid line and the error is about not allowing nulls in the column.  Shouldn't this be what is handled by the ModelState.IsValid line?  I feel like I am missing something obvious. 


Strongly typed dataset exception handling

  

Hey everyone,

I'm currently working on a 3-tier ASP.NET application (UI, BLL & DAL). The DAL uses a strongly typed dataset that I've created with the VS Dataset Wizard. My question is, what is the best way to handle exceptions originating from the BLL and DAL classes. I googled a bit and it seems that the most commonly used practice is to create DALException and BLLException classes and throw your own message. Is this the way forward? Could you please indicate how this can be done for an automatically generated DAL? What are the best practices? Examples with code are highly appreciated!!


Thanks,

Clayton


Using a partial in a strongly typed view

  

I have an application that is going to allow a user to create records of type Customer and Seller that have one section in common, but other fields that are unique to their types.

Both of these types will have an address block for their create view.

If I have a strongly typed Customer or Seller view, how can I use the view partial (containing the address block) that I've created? I've tried creating a view model, but I don't know how to have the create page inherit the Customer model and the addressBlock partial inherit the addressBlockForm partial model...

Hopefully, this makes sense, and thank you for any help.


Strongly typed view and viewModel

  

Hello together,

I have a question about strongly typed views.

I already have my business objects (based on the persistence framework xpo form dev express). These objects have some associations.

eg. an article can have some user comments

article.comments

My question now is, should my strongly typed views directly base on this objects (even if these objects have many properties i never need to present)

or should i create additional classes containing only the properties of the objects which i like to present.

eg. articleViewModel and commentViewModel.

where a articleViewModel can have associations with multiple commentViewModel


The advantage which i see in the second example is, that i can easier validate the viewModels.

However it means a lot of extra work, because i need to create for all objects which i like to present a viewModel with the corresponding

associations and properties.


Thanks a lot!

MVC2: Change the default generated HTML when creating a strongly typed view

  

Is there any way to change the HTML that is generated by default when you create a strongly typed view in MVC2?

I currently get a structure like this:

<fieldset>
            <legend>Fields</legend>
            
            <div class="editor-label">
                <%: Html.LabelFor(model => model.category_id) %>
            </div>
            <div class="editor-field">
                <%: Html.TextBoxFor(model => model.category_id) %>
                <%: Html.ValidationMessageFor(model => model.category_id) %>
            </div>
</fieldset>

I want to change it to a structure like this:

            <div>
                <div><%: Html.ValidationMessageFor(model => model.user_login) %></div>
                <div><%: Html.LabelFor(model => model.user_login) %></div>
                <div><%: Html.TextBoxFor(model => model.user_login) %></div>

Strongly Typed HtmlHelpers and View Models

  

Hello,

I am not sure why this happens, but when I have an Html.TextBoxFor(model => model.SomeObject.SomeProperty), when I post, the property of that object is always null.

When I look at the markup generated, I see <input type="text" name="SomeObject_SomeProperty" id="SomeObject.SomeProperty" value = "" />


If I change the helper to Html.TextBoxFor(model => model.SomeObject.SomeProperty, new {id = "SomeProperty"}) the controller is then able to pick the value up. Why is this happening? I feel as though I shouldn't have to be specifiying the id for the textbox as it works when fine when not using child objects on a view model, IE <%: HtmlTextBoxFor(model => model.SomeProperty) %>.


Upload with strongly-typed view - Create Method

 How i can translate "TextBoxFor" to "UploadFileFor"?


Downcasting to base class Strongly typed view

  

I have the following entity object:

    public class ForumPost
        {
            public virtual int ForumPostId { get; set; }
            public virtual int LoginId { get; set; }
            public virtual string Body { get; set; }
    ...




 
Then I have page that would has a list of ForumPost(s) and and edit option, all on one page. To achieve this I've created a CommentsViewModel that extends "ForumPost" class like so:

    public class CommentsViewModel : ForumPost
    {
        public IPagedList<ForumPost> ForumPostList { get; set; }
    }




This way on my view I can have a list of ForumPost(s) and a form that would edit the post.

This is what i see in the debug mode right before the save call:


The problem is that when I try to Save/Update I get the following error:





I already tried doing this:

this.ForumPostRepository.Insert((ForumPost)model);
