MVC :: Show A Model Item As A Drop Down List Or Radiobuttonlist?
Aug 12, 2010
I am working with a model which has the following, basically a Project can have a score between -5 and 5 and I'd like to show a dropdownlist of the available options, i.e 5,4,3,2,1,0,-1,-2,-3,-4,-5.
[Required(ErrorMessage = "Score is required")]
[Range(-5, 5, ErrorMessage = "Score must be between -5 and 5")]
[DisplayName("Score")]
public double Value
{
get { return value; }
set { this.value = value; }
}
What would be the best way to accomplish this using a dropdown list and how can I make the score of 0 the
default selection?
I'm using Model-View-Presenter framework. When Loading a page, I'm having trouble setting the selected item that came from the Database.
In view, I know I need:
protected void ddlStatus_SelectedIndexChanged(object sender, EventArgs e) { presenter.DdlStatusSelectedIndexChanged(); // what should this pass? } Then in Presenter: public void DdlStatusSelectedIndexChanged() { view.DdlStatus = ??? // Should I pass the SelectedIndex? }
I also think that part of my problem is that DdlStatus I have as a List.
Interface:
List<StatusDTO> DdlStatus { set; get; }
The best I found is here (but needs formatted!) ---> [URL]
I have a requirement in my application that, while saving the application, need to get all the value from drop down list and pass it to the view model. But application should not allow the user to select more than one item from drop down list manually, ie, only one value at a time. My view model is like ...
public class ListManagement { public IEnumerable<selectListItem> InactiveProduct { get; set; } public string[] InactiveProductSelected { get; set; } public IEnumerable<selectListItem> ActiveProduct { get; set; } }
I have a list with 2 sorts of items. Items that have actual values (1,2,3,4 etc) and items that are like group headings so all their values are set to 0. If someone decides to select a group heading - which has a value of 0, is it possible to redirect them to my 'Select an item' item which has a value of ""?
If worse comes to worse, I can just reconstruct the entire list, although if possible I'd like to avoid it.
I have two drop down list on a page. The first one list projects and the second list users. The userlist is populated with an object datasourse that pulls a list of users for the selected Project.Whenever the Project list selection changes the second ddl Userlist always reverts to the first person in the list instead the person that was selected before a new Project was chosen.
I have drop down list box that I would like to show two columns, is this possible? Or can it be done with a list box?The query correctly retrieves all of the table data to be displayed, one colum is an abbreviation, the other a bit longer description.
How can I make the first item in a drop down list non selectable. I want this first list-item to show up when the page is opened and want to populate the rest of the DDL from a backend DB. I don't want this default first item in the list to be selected (just want to show it as a default value)
I want it to look something like this.
Choose a State: (Appearing on the top of DDL, but cant be selected)
I am trying to set the item that is selected from a drop down list based on what it in the database for that particular record. I am filling the dropdown list with a SQL DataSource I have tried a couple of example that I have found for selecting the item in the list but I am always getting the first item in the list as the selected item. This is what I am currently working with:
Code:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
I fill a the drop down list with a SQL select query, but i want to add a first default item, something like "- Select an option -" or "All"
What im trying to do is make a dynamic SQL query, something like this:
SELECT * FROM table1 WHERE (value1 = ? AND value2 = ? AND value3 = ? )........ (or "like" instead of "=")
You are gonna have to select those arguments from 3 drop down lists, but i wanna have a default value on the top of the drop down list options and send a "*" as value if this option its selected, so the filter doesn't consider that value
I have a asp.net mvc view which is strongly typed view and i have a controller which returnsthe ilist user based on the id provided. I am getting the following above error:
The model item passed into the dictionary is of type 'System.Collections.Generic.List`1[Data.User]', but this dictionary requires a model item of type 'Data.User'.
how do i get the selected item in the drop down list and insert it into database (togethi populated the drop down with the values from the tables in database. It is dynamic, not static.i have a button in the gridview called 'add'. so when user clicks on it the row (whatever columns in the row) would be inserted into database. i am doing insertion/create for this.
Alright heres my scenario. I click on an event and a new aspx page opens. I have two drop down lists and three text boxes. All populated with the data from the database. But when the page opens the drop down lists always show the item that is at the top of the list. Not the actual item that is in the database.
So say the name John should be there in one and a car names honda. But instead it shows alex and acura. These are just examples. But it alwasy starts with the item at the top
In my application i used drop down list dynamically so that if i enter the the value in the text box that many drop down list genrated with data from database. if i select the different iteam in the drop down list it will not changed it remains the first iteam of the dropdown list. if i use post back event is true in code part that drop down list is not visible.
nt i = 0; i < rows; i++) { TableRow row = new TableRow(); for (int j = 0; j < column; j++) { TableCell cell = new TableCell(); [code]...
I've got a drop down list that I want to populate with items from a SQL Server database, which I did successfully, but I can't figure out how to write an if statement that will clear the drop down list based on a selected index and repopulate it with data from another table. The drop down list is inside an update panel that auto posts back.
Basically I want to allow the user to choose an item, but rather than populate another drop down list control, i just want to repopulate the current one with new data.I'm guessing that if I want to get data from more than one table the code below isn't going to work for me. Could I get the data from all the tables at once and store each table data in its own variable until I need to use it? (Each table will have under 10 items, in 5 tables.)
Here is the code to get the data from the database:[Code]....
n a form I have multiple group of controls which are grouped using validation group property. I want to assign validation group to asp.Button dynamically on client side using javascript on the base of item selected in drop down list.
Here is JavaScript which I am using, but it is not working. It shows validation group undefined but actually a default group is defined.
<script type="text/JavaScript"> function NextClicked() { var _ddlStatus = document.getElementById("<%=ddl.ClientID%>"); var _selectedIndex = _ddlStatus.selectedIndex; var _btn = document.getElementById("<%=btnNext.ClientID%>");
alert(_btn.ValidationGroup); // here in messge it shows undefiend, yet I have defiend a group in button as default.
if (_selectedIndex == 1) { _btn.ValidationGroup = "G1"; } if (_selectedIndex == 2) { _btn.ValidationGroup = "G2"; } }
I have a drop down list that has the initials of about 12 of our sales guys.How can I make it so that when they select their initials from the list, the next drop down list only shows their customers.In my database there is a column for customer name and salesman.
I am trying to get a drop down and a form view to work together. I've never used form views before. I also am using the entity framework to do everything. This is also my first time with it.
I want to be able to have a drop down, that is populate from the same data source as the form view. So far that works fine.
I then want to be able to change the drop down item, and it change the form view item that is displayed. I cannot figure out how to make this work.
How can I have 2 Cascading Drop Down Lists for the same Drop Down List?here is my problemi have 3 drop down lists read from database1- Schools List 2- Classes List3- Teachers ListEvery School will have more than 1 Class and more than 1 TeacherWhat I want is when user select a School from Schools Drop Down List then BOTH (Classes and Teachers) should be refreshed based on the School Drop Down List
In an ASP.NET 2.0 project I've got a RadioButtonList. I'd like to disable one of the items in this list, but when I change the Enable property of an item to false it just wrappers the item with a span instead of disabling the Input when rendered to Html:
I have a table cell with a RadioButtonList. When each item is selected, the SelectedIndexChanged event is supposed to fire so the app can populate a related listbox. The problem is it stopped working. Now if I selected the first entry 'Division', the event never fires. I put a break-point on the event handler and it gets called for the other entries but not for Division. I'd believe it if some other code is interfering, I just don't know where to start looking.
[update] By not working, I mean if you selected Item #2, the update works; then if you select Item #1 it doesn't. If I change where the 'Division' item appears in the list, it still has the problem. Is there something in the page load cycle that could be aborting the event handling chain?
Is there a way to set tab order on each ListItem within a RadioButtonList? The listitem does not have a TabIndex attribute, so can this somehow be done via javascript?
A similar thread indicates there is not a way to do this [URL], other than using individual RadioButtons instead of a RadioButtonList.
