How can I use DisplayForModel in a loop with a View for which I've passed a collection of objects? That is, within the loop I want to call DisplayForModel each time for the specific object (not the collection). Or does MVC not currently support this?
So I'll like to be able to do something like in the below, but this itself doesn't work.

I watched the intro video atleast 20 times trying to figure out how Phil used EditorForModel instead of the generated Edited fields when using Add View > View content(Edit).
How do you use a class (entity) instead of the generated fields?
How can i use editorfromodel and dropdownlists that are to be populated by tables in my model? Seems i can use custom templates to format the major datatypes like datetime, string etc but i how can i manage select lists or dropdowns since i cant pass classes into editorformodel..
Is there a way to force a particular field to be formatted as a dropdownlist in editorformodel?

In my LogOnViewModel.cs :[Code]....I have this code, and on the view control, i call <%: Html.EditorForModel()%>
Then I have something like this look:
UserName:|||||||||||||||||||||||||||||||||||| <- TextBox
Password:||||||||||||||||||||||||||||||||||| <- TextBox
ㅁ <- Checkbox
||Login|| <- submit button
how do i change the layout of this template? I want to change the text and change the position of the textboxes.I know that I can customize it by calling individual fields and write hard-coding, but I am curious if there is a way to use EditorForModel() in easier.
I am learning MVC using the v2 release with Entity Framework v4. Let's say I have 3 objects Game, Points and Players. They are related in the following manner:Game has points and the Points can have a player associated with them ( 1 Game to many Points and a Point object can have one Player).
I am attempting to use the EditTemplates feature in MVC2 to render my views. In my Game Edit view I want to have the basic Game object information editable, and also the related Points objects. Currently I am utilizing "`<%= Html.EditorForModel() %>`"(Which seems pretty slow) to render the Edit View and then I have a specific Game and Point EditTemplates.
The data renders correctly and is editable for both the Game and Point information. When I go to perform the update and submit the form I receive the "Game" object in my Update ActionResult. The basic properties are populated for the Game object but any deep properties such as Points are not; they appear as null. If I look at the Request.Form variables in debug I can see the Points fields are being passed to the server but do not place themselves back into the Game object.
In my Game EditTemplate I am using the following to render the Points objects:
<%= Html.EditorFor(c => c.Points) %>
My Points EditTemplate looks like: [code]...
why this is rendering as "Points.Points[index] instead of Points[index]? I tried messing with the parameters in the EditFor:
<%= Html.EditorFor(c => c.Points,null,"Points") %>
but then the inputs render as Points.Points[index]
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."
Somebody knows the answer? I'm using L2S with field ntext in my db
View 1 RepliesI've been tinkering with the Nerddinner tutorial (upgraded to the new MVC 2.0 version actually) and I am trying to figure out how to dynamically hide/show fields in the EditorForModel template.I have added a new field to the model and a dropdown list for it in the editor, and I would like to be able to toggle the visibility on a couple of textboxes if a user selects a particular value from the dropdown list.
I did manage to access/manipulate the values of the textboxes using javascript (by altering the "onblur" example in the tutorial app), but couldn't figure out how to access the properties of them.
I have written an Enum extension method that allows me to create a view model and allows me to easily bind a generic Enum to a SelctList like:this.ProductStatusList = new ProductStatusTypes().BindToSelectList<ProductStatusTypes>
(product.Status.ToString());
In my View I can then have:
<% using (Html.BeginForm()) {%>
<fieldset> [code]...
Notice I am using EditorForModel and then a seperate DropDownList. My question is: Is there a way to get the EditorForModel to be clever enough to pick up that I want to use a SelectList instead of a TextBox for status?
i am working an asp.net mvc 2 web app using model metadata and some of the model metadata don't seem to work when using the default Html.EditorForModel().For example, when applying the DefaultValue(1) and the ReadOnly(true) attributes on a model field, the field displayed on edit view has zero for its default value and it is not read only.
View 5 RepliesI want to know that how i use the collection class for storing some data and save it letter in the data base.
View 4 RepliesMy test shows it doesn't work. It ignores the nested data in model.
View 1 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 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 4 RepliesList<Dictionary <string,object>> I am reading about the list and collection, If possible, what are the different ways that I can utilize the list of dictionary collections..... gives me different examples or areas where I can use it.
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.
mvc-ers in the Model i have a collection of Employees (EMPLOYEE_ID,
FIRST_NAME,
LAST_NAME,
MOBILE)
and i want to send particular fields from it to the view so in the Controller i write this code
[Code]....
how can i retrieve the collection in the view, should i create a class contains (e.EMPLOYEE_ID, Employee_Name)
and cast ViewData["Employees"] to it, or there is a trick?
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"]; }
set { ViewState["CachedItems"] = value; }
}
private void AddToCachedItems(MyClass item)
{
CachedItems = CachedItems.Concat(new[] { item }).ToList();
}
