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?
i have the following code:

3 nested dropdownlists SELECTing from DB. So i select the brand, then i select the model and then i select the product and click on SEARCH button.
But when i select thebrand, and then the model, and if i want to change the brand, it does not reset the second and third dropdownlists.
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?
I'm wondering how I can make one dropdownlist affect another one.. For example...You select your country from a drop down list of countries. On selecting it, another dropdown list becomes visible and displays the states of your country. I'm taking this data from a database, so it merely has to link to a different table for each country selected.
Also, I want the option of being able to add a 'state' to the database from the webform by typing whatever its called into the combobox so that future users will see that option.
I tried view and model below in MVCMusicStore sample in .NET 3.5 MVC2 .

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]
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.

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 RepliesMy test shows it doesn't work. It ignores the nested data in model.
View 1 RepliesI'm using a code I got from CodeProject [URL] about a validator that can monitor 3 form controls. I pasted it to my site, changed it to suite my parameters but seem to encounter a situation that can't satisfy my desire: Instead of making sure that all the 3 DropDownLists are filled without their default value, the validator cares only if at least one has been filled, and if so, he can call it a day. look at this code at tell me what am I doing wrong?

I have to generate multiple dropdownlists on clientclick. That is new dropdownlists on every client click.
I placed a button and wrote code on click event. protected void addReq1_Click(object sender, ImageClickEventArgs e)
{
DropDownList oDdl = new DropDownList();
oDdl.ID = "ddlReq" + (++i).ToString();
oDdl.DataSourceID = "DSUsers";
oDdl.DataTextField = "UName";
oDdl.DataValueField = "UName";
HtmlTableCell tc0 = new HtmlTableCell();
HtmlTableCell tc1 = new HtmlTableCell();
HtmlTableCell tc2 = new HtmlTableCell();
HtmlTableCell tc3 = new HtmlTableCell();
tc2.Controls.Add(oDdl);
HtmlTableRow tr = new HtmlTableRow();
tr.Cells.Add(tc0);
tr.Cells.Add(tc1);
tr.Cells.Add(tc2);
tr.Cells.Add(tc3);
search2.Rows.Add(tr);
}
Here "DSUsers" is SqlDataSource. "i" is static variable. "serarch2" is html table with runat server tag The problem is only one control is getting rendred, after that on every additional click same DropDownList is getting replaced. No new DropDownList is added to the page.
I have created a label and a dropdownlist. The label has the dropdownlist as associated id.If I click on the label and then uses the mouse up or down the dropdownlist creates a postback for each click. This is quite anoying and doesn't happen if you click on the dropdownlist and uses key-up or key-down, or if you uses another browser than IE.Is it possibel to fix this, so you can use key-up and key-down without causing a postback, and first on the enter-key creates the postback (as it does if you click on the dropdownlist and not label)?
View 2 RepliesI am trying to use two DropDownLists (Cities, Categories) in a PartialView that will be used in MasterPage, meaning they will be visble all the time.
I tried to load them in HomeCOntroller, but that didn't work. I got an Exception.
I read something about making a baseController that the other controllers will inherit from, I have tried that, kind of, but I guess i'm doing something wrong.
This is the only code I got today:
Masterpage

PartialView (SearchForm.ascx)

Two question:
Where and how to load the DropDownLists is the problem. I have tried to load it in the HomeController, but when go to another page then it says that the DDLs is empty and I get a Excecption. Why do I have to use two forms for the ActionMethod to trigger ?
On my webform, I have 3 dropdownlists with datasource to SQL. Through dropdownlists, I want the user to fill the controls, so I can get his location. One for his area, subarea, town or village. Actually the values appears great but I dont like when my page loads, the ddl fills with default values and second when I change, lets say the first ddl, it also full fills the rest with the first default values. All I want to do is, load my page with empty values, assign a value at first ddl, the second remains empty til I click on it and select a value and so on.. here is the code i use
HTML Code:
<div id="CreateAccountDiv" style="padding-top:10px">
<%--Label and Textbox for company--%>
<div><asp:Label ID="lblComp" runat="server" Text="επωνυμία επιχείρησης" CssClass="sizeLabel" ForeColor="black"></asp:Label></div>
<div><asp:TextBox style="width:250px;font-size:10pt" ID="txtComp" runat="server" CssClass="sizeText transparent" ValidationGroup="form">

I have a dropdownlist on my page which has autopostback set to true. On postback I populate a runat server div with a bunch of other DropDownLists. I then have a button which does another postback to save the selections. Because the second set of dropdownlists are dynamically generated I cannot for the life of me figure out how to get their selected values?
1st DropDownList
[Code]....
Then when I try get the dropdownlists using a foreach on the div that I added the control to it does not work. They are populating fine, its just on the button click. I have tried EnableViewState = true on the dropdownlists and my code is correct because if I code them into the aspx then it works, its something to do with the state.
I have got 2 Drop Down Lists on my Form and 1 GridView. I want GridView to display the data according to selection from the Drop Down Lists.
For Example, One Drop Down List contains Names and other contains Dates. Both the Drop Down Lists can post back. So if i select a name from 1st Drop Down list, the Grid View should show all the results according to that Name. Similarly if i select the Date from the other Drop Down List , the Grid View should show the results according to the dates. But i cant figure out as how to bind Grid View to respond to 2 Drop Down List.
i am binding both the Drop Down Lists and the Grid View to the DataSource Objects, which is getting data from the database.
I'm trying to generate some dropdownlists trough code. but i can't seem to access them.

View 6 RepliesI'm trying to use two cascading dropdownlists with the same values -- one shows a code, and the other a description. They are sorted alphabetically, so they have the same values, but not the same index. Both are generating correctly. What I am trying to do is set the abbreviation when the description changes (and vice versa).If I use this javascript, it changes on the web page, but I get a null value returned to the form handler. If I comment out the CascadingDropDown control and load the TrickAbbrev from a database it all works.

I want to assign same datasource to multiple DropDownLists in a form, when the page loads, only the first drop down list has filled the content of datasource, others are empty, what's the missing point? Here are the codes;

<asp:ScriptManager ID="scriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel ID="panel1" runat="server" UpdateMode="Conditional">

I have an SqlDataSource at the moment, which I want to be able to be filtered using 3 DropDownList's. Basically, each DropDownList contains values for a certain column on the table, so when they choose one of the values, the SqlDataSource only shows values with that value in the relevant column.
So my table is somewhat like this:
ID (primary key)
ManufacturerID
ItemTypeID
UnitTypeID
And the 3 DropDownList's contain the following:
Manufacturers (value = ManufacturerID)
ItemTypes (value = ItemTypeID)
UnitTypes (value = UnitTypeID)
My filter expression for the datasource is currently like this, but it doesn't seem to work unless all 3 boxes have a value selected, which is not ideal. Any ideas guys? My filterexpression is below:
ItemTypeID = {0} OR ManufacturerID = {1} OR UnitTypeID = {2} OR (ItemTypeID = {0} AND ManufacturerID = {1}) OR (ItemTypeID = {1} AND UnitTypeID = {2}) OR (ManufacturerID = {1} AND UnitTypeID = {2}) OR (ItemTypeID = {0} AND ManufacturerID = {1} AND UnitTypeID = {2})
