Given the benefits of using strongly typed views to eliminate typed errors and the use of lambda expressions why would one use a dynamically typed view? When I use them I don't feel as safe as with strongly typed views. Am I missing something? Is there a special use for them?

I've developed an application using strong-typed dataset with .net framework 3.5.is there a way to change the source table for a tableadapter programmatically?
View 1 RepliesIn my project I use Strong Types Views. Because I find it nice structured.
public abstract class AbstractViewData: View Page ( ICollection Foo; )
public class HTML Component View Data: AbstractViewData ( string Foo2; )
I have the same structure in my code, as in the corresponding pages.And here starts the problems. I would like to use HTML.Display (o => o.Foo) could be a customer for that matter.But my Strong Types Views have not posted Metadata Model into my classes.Like: Return View ( "FooView", customer); would.Is there a way to write some code that can solve this problem for me?
Got a werid problem with a view, if i define it with Inherits="System.Web.Mvc.ViewPage<List<Tuple<string, DateTime?, double?, double?, double?>>>"
i get the werid error:
CS1003: Syntax error, '>' expected
Line 118: public class views_report_intrestcalc_aspx : System.Web.Mvc.ViewPage<List<Tuple<string, System.Web.SessionState.IRequiresSessionState, System.Web.IHttpHandler {
But it workes perfectly if i remove the last", double?".A bug in the asp.net comiller?
Just a quick question really but with the strongly typed views where MVC can autobind form fields to the propertys of an object I define, how does this work when supporting multiple forms on the same view?Is it possible to have two objects with different properties,
Object1 { Name, Age }
Object2 { StartDate, EndDate }
Then on the view have two seperate forms, one for each object and the controller can work out which object it is to post back because of the form which eventually gets posted back?
I am trying to get my head around the sharp architecture and used the visual studio template as described on the web:[URL] This is all cool. Unfortunately, I cannot add a strongly typed view as easily as I am used to 'under' asp.net mvc.
What can I do to 'enable' this in VS 2008 Prof? I have also installed asp.net mvc 2.0 and would like to reflect this in my 'vs studio sharp environment'.
<p>Hi</p> <p>I'm a newbie in MVC but a veteran web forms developer. I really like the idea of strongly typed views but what if I have multiple objects to pass to my razor view. Would I then NOT use strongly typed views and just use the ViewBag?</p>
View 3 RepliesLong story short, I'm trying to add a few extra items to ViewData to make my life easier, and its an edge case that doesn't really justify its own model just for this one case. Keep reading for more specific details.
So I have a strongly typed edit view for one of my objects, everything works great until I try to put a dropdownlist on the view with an ID that does not match a property of my class.
I have this
[code]....
My expectation is that in the controller action that accepts the POST, I will manually use the FormCollection[] to read out that ID and populate MyOtherModel with the correct ID.
I would rather not magic string my DataTextField/Values on the dropdownlist after setting up the source as a List collection of objects.
I was thinking I could use the DataSource properties but it doesn't seem to like the couple of ways I tried.
WORKS BUT NOT IDEAL
//set the datasource to the returned List<Cart>
this.cartDdl.DataSource = CartManager.Load(WebProfile.Current.UserName);
//set the DataValueField to the Cart.ID property
this.cartDdl.DataValueField = "ID";//would rather use the obj property Cart.ID
//set the DataTextField to the Cart.Description property
this.cartDdl.DataTextField = "Description";//would rather use the obj property Cart.Description
//Bind the ddl to the datasource
this.cartDdl.DataBind();
HOW I WOULD THINK IT COULD WORK this.cartDdl.DataValueField = ((Cart)this.cartDdl.DataSourceObject).ID; this.cartDdl.DataTextField = ((Cart)this.cartDdl.DataSourceObject).Description;
i am created a Template for showing dropdownlist when i used the Template by this code
<%= Html.Editor("ItemStatusID", "ItemStatusList")%>
i did see a text box no dropdownlist this is my Template
[Code]....
So my question is more in relation to what people consider to be the best practice and why:
I've been dropping literals into pages and repeaters and binding them in code behind for a while. Is this considered bad practice?
ie:
ASPX Page:
<asp: Literal id="litTextToInsert" runat="Server" />
Code Behind:
litTextToInsert.Text = objData.MyText;
OR (repeater):
[code]....
I personally dont like doing this as i find it makes it harder for me to know if someone changed the field name, or mis typed it during development - the other way you won't know until the page loads.
With the strongly typed version if something changes in your DAL etc the build will break - letting me know I've messed up.
Why do so many people appear to use weakly typed code in ASP.Net (in examples, MVC, etc)?
Am i missing something?

My problem is that I'm having problems figuring out how to add a templatecolumn with a dropdownlist in it.
I have a transaction table with a field called product. There is a limited number of choices for product so I also have a product table. I am showing the transactions in a ListView with a dropdownlist for Product. The field Product can be blank (all works well then). The user can leave the field blank or they can choose from the dropdownlist. I am running into a problem with the dropdownlist in the Edit Template. No matter what the product is in the transaction file, I get a page error of "ddlEditProduct has a SelectedValue which is invalid because it does not exist in the list of items". I have verified the product does exist in the product table.
<asp:DropDownList ID="ddlEditProduct" runat="server"
DataSourceID="dsProduct"
DataTextField="Product"
DataValueField="Product"
AppendDataBoundItems="true"
SelectedValue='<%# Bind("Product") %>' >
<asp:ListItem Selected="True"></asp:ListItem>
</asp:DropDownList>
In my edit template I want a dropdownlist containing a list of possible customers. The list is populated from a database table containing existing customers. If the main record has customer "XYZ", then I want that customer to be the default in the dropdown. I'm using VS 2008 and C# My markup for the dropdownlist is currently:
[Code]....
The dropdownlist is populated but the problem is it shows the first customer in the list. I don't want the user to have to rechoose customer if that is not what they are changing.
I am using Asp.net with C#.
I have one gridivew, which is showing 20 records. And also, in item template of Gridview, I used one dropdownlist. It means there are 20 dropdownlist with all the 20 rows. That dropdownlist is already binded, means showing the records/items - 8 items. No issue with this.
Now, what I want is, when ever, I select any item from the drodownlist against each row in that gridview and click on the button "Save", it will save the id of all row with all the values of dropdownlist.
I have a template field in a Details View which is a dropdown selection of values.While I can get the value of the textfields in the DetailsView by using: DetailsView1.Rows(i).Cells(1).Text.ToStringI don't know how do extract a value from a dropdownlist2 contained in the DetailsView.

I am trying to change the textboxes in the FormView insert template to dropdownlists but they keep setting the parameters to null. Here's what I have:
[Code]....
In Page_Load
CType(frmSurvey.FindControl("ddlYearOfQualification"), DropDownList).Items.Add(New ListItem("2010", "2010"))
CType(frmSurvey.FindControl("ddlYearOfQualification"), DropDownList).Items.Add(New ListItem("2009", "2009"))
and in the SqlDataSource
InsertCommand="INSERT INTO [tblSurvey] (... [YearOfQualification] ...) VALUES ( ... @YearOfQualification ... )
And in insert parameters:
<asp:Parameter Name="YearOfQualification" Type="Int16" />
And the insert fails with YearOfQualification as null. If I sue the standard textbox:
<asp:TextBox ID="YearOfQualificationTextBox" runat="server"
Text='<%# Bind("YearOfQualification") %>' />
In my listview object insert/edit template, I have two dropdownlists (category, subcategory). When a user selects a category (autopostback), I would like the subcategory dropdown to filter to only the those that match the categoryID from the category ddl. This seems to be complicated by the fact that it is in a listview object. I'm currently using a queryextender on the subcategory datasource, but I'm not sure how to apply the selectedvalue of the category to the queryextender. The subcategory just shows all items and is not filtered. How do you accomplish this?
View 1 RepliesI've been struggling with trying to figure out how to do this for about 2 weeks now. I have a DetailsView with several template fields in it. The first field (Unit_Code) is a dropdownlist item where the user would select a Unit based off the Unit_Code's Unit Name. Further down I have a field named (System), system needs to get it's value from the selectedvalue or selectedindex that the user selected in the (Unit_Code) dropdownlist. I have another dropdownlist item (Component) that will need to get the selected value from System to sort on, so once I have the first Unit_Code to System figured out I should be able to figure out the System to Component part seeing as it will basically be doing the same thing.

I am trying to bind dropdownlist in Gridview under EditItemTemplate under RowBound event. But it gives me blank rows in the drop down list.Here is my DesignÂ

I see the dropdown but the dropdown is blank, but there are rows in the database for this column and in the footer row it is working fine.
