MVC :: Form With Data Of Different Models And With Dropdown List
Feb 16, 2011
I am working on the following form: This is a smooth popup, I make it appear through ajax using:
$.get('/UsuariosEmpresa/Create/', function (data) {
$("#AltaUsuarioProtectiveLayer").fadeIn("fast");
$("#PnlAlta").html(data);
});
What is great. And the View for create has the following code:
[Code]....
By now I have this two Save Buttons, Save and btnGrabar, just to test. When I use Save it is sending all the information, but not the values for the "Grupo" and "Empresa" dropdownlists. I am trying to use an Editor Template, but I don't know if is the best way, or is better to make in another way: 2 pages, one for create and one for edit. I have the following ViewModel that I try to use here:
[Code]....
And the dropdown list are in the editor template in this way, they are relation dropdownlist so depending on the Grupo=Group will show the corresponding Empresas=Companies:
[Code]....
And there is the problem I believe. The db diagram for this part is the following: The question are:
a- What is the best way to do this?
b- Is ok to use a template?
c- How should I send the information to save correctly the id_Empresa value?
d- Is ok to use the ViewModels or is better to send all the values as $.post parameters?
e- Is ok the way I cascade the dropdownlist?
I am stuck at this point "Displaying a dropdown list of Categories with a --None -- Option. I want the gridview control to display 2 dropdown list one in read-only mode and the other in edit mode. When a record is in read-only mode, the dropdownlist's enabled property will be set to false."When it's on a read-only mode, it doesn't display the selected Category. it shows but the "No Category". When i click on edit to edit or change category, it doesn't display the selected category.
The example is given below( I am reading the book Sams Teach yourself ASP.NET 2.0 by Scott Mitchell. page 628)

I've a product model that contains a list of description models. Every description model contains some string values because every product can have a description for every language. Here it is a semplified version of my models:
[Code]....
So my view to insert a new product is like this:
[Code]....
And my PartialProductDescription view is like this:
[Code]....
Now, the views are perfect. With some Jquery UI I have a form with all the product properties and a tab panel with the language descriptions.
Unfortunatelly my POST action with the firm public ActionResult ProductNew(ProductModel model) has all the model property InternationalDescriptions that contain 2 empty models. So if I write something in the form in the first description textarea, model.InternationalDescrtiptions[0].Description is always empty.
So, how I can tell to MVC to take description textarea values and put them in the model?
I have a databound dropdownlist and have a problem with the default value it selects.When I attempt to edit a record the dropdownlist shows the first value in the list rather than the current value. I want the dropdown list to display the current value.
I'm sure this is very simple but I'm very new to ASP.NET.
I have 2 drop down lists.I have a very simple dropdown list #1 that diplays a title and holds an id value which is a GUID.I know it is getting this value and sending this value as I tested sending it to a label.I have the dropdown list #1 to autopostback to dropdown list #2 that "Is supposed to get" another title and value based on the GUID value of the first dropdown list. for some reason it wont return anything. I have done 100's of these but never based off a guid value.I assume the value needs to be converted to guid before selecting it in the second dropdown list.How can I do this? or is there something I am missing?
Does anyone know how to do this so when I select something the 1st dropdown and the 2nd one becomes visible and populates list from a Select statement. I really need help on how to do in an aspx and not on the code behind page.
I Have the gridview control with 2 dropdown list and 2 text boxes,When the textbox chnaged event happen 1 row will create and the dropdown back to initial values( its not retaining the selected values),I am binding the control after text changed method,Is there any properties needs to be set or any other way we can retain the values in postbacks?
I have a category and a subcategory column in a Jqgrid. I have enabled inline editing, both category and subcategory are dropdownlists columns (edittype:'select'). I need to filter the subcategory list based on the selected category. I wonder how can I acheive this functionlity? I tried the below event but its not working for me
afterEditCell: function(rowid, celname, value, iRow, iCol) { //to do here }
the above event doesn't get fired. my all column are editable
I have a photo website with a login page. (It is an exercise out of a book: Scott Mitchell's "ASP.Net in 24 hours".) After a user logs in he can go to another page and manage photo categories. That page works. I have two users that have photo categories setup in the database.
There is also a page where a user can add photo images. This is the page that is giving me problems. It has a name and description field. (The functionality for uploading a photo is next in the book. It is not on the page yet.) The page also has a dropdown list that is supposed to be populated by the category names of the logged in user. This is the control that is giving me problems. It is not being populated by the logged in user's Category names.
The two database tables used are pretty simple:
[code]....
There are two SQLDataSources on the page:
One is for inserting new photos. The other retrieves the Categories of the current user. The page has a DetailsView with the Photo's Title and Description. There is also a dropdown list with the Category names. It is aa InsertItem Template in DetailsView.
When the page opens, the current UserID is retrieved and put into a Hidden Field. It is then used to retrieve the Category Names by the second SQLDataSource. I have gone through the book's steps a few times now. The dropdown list is not being populated. I am not getting any errors.
How can I track down why the dropdown list is not being populated?
Both of my users have Category values set up in the database. So, the dropdown list has values that should be appearing.
i have two drop down list in web form..for both of them i've used following code to bind with sql..but whenever i'm trying to bind second drop down list with same method..it's giving error.. the code i've used:
one drop down list cointains all country list ,when we select thet particular country the other drop down list has to show all the states in that country ,this is what i am thinking to do ,can some one guide me how to do ,and give you give some reference links
I have a web form where there are couple of DDL's; DDL1 and DDL2 respectively. I want the DDL2 to be populated based on the selection made in DDL1. From the DDL1, I just want to extract the first three digits of the value selected in DDL1 and use it in the WHERE clause of SQL query which is used to generate DDL2.
My prob is that I am not able to extract the first three digits out of DDL1 and use it in the WHERE clause of DDL2. I have pasted all my code below:
Protected Sub DropDownList2_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Dim ddl1Value As String = DropDownList1.SelectedValue ddl1Value = (ddl1Value.Substring(0, 3)) SqlDataSource3.SelectParameters(0).DefaultValue = ddl1Value SqlDataSource3.DataBind() End Sub
quantity is in databound in gridview and it will show quantity of users order...
now I want in quantity column in gridview I can put Dropdownlist that will fill with numbers that if users want increase their order they can do it from gridview...
How can i generate dropdown lists based on what has been selected in the checckbox list. Below is an example of what i need. if the user selects the options day, lotID and waferID, then 3 cascading dropdown lists should be displayed. And then a gridview displays data based on what has been chosen in the dropdown lists.
Day LotID SlotID WaferID VendorID ToolID LocationDetected ProcessStep Stage Precipe WaferStartMaterial WaferStartVendor WaferStartLot WaferDiameterCOA WaferMapTitle BreakPoint BreakpointSide BreakpointMeasurement
Clicking the label of a drop down list, re-sets the selected value to the first item in the list. This has a history of causing data entry problems when users accidently click on the label.
In the below example ddlContactType has a selected value as 'PRIMARY' and whenever i click on the lblContactType Text, the dropdown box Selected value is changing to "Select One" Text.
How to prevent this one. It should be on PRIMARY Only.
I'm trying to progam a strongly typed "Create" view using MVC 3 and razor. I want the user to be able to select a customer from a dropdown list (I populated this from my database using ViewBag in the controller). When the user has selected a customer I want a separate dropdown list to generate a list of dogs belonging to that customer related by the customerID in the database. The create button on the form will then take both of these values along with the the other fields and save it to the database.
1. I am new to ASP and I can not get this to work:
2. I am Using a <asp:DropDownList in a <InsertItemTemplate> in a <asp:ListView
3. The dropdownlist during insert does not get polulated (it is empty) while the same construction and same datasource works in the edittemplate: <asp:DropDownList in a <EditTemplate> in a <asp:ListView
4. I noticed that filling the dropdownlist with a <asp:ListItem works; the insert list is populated. (not usable for me) In both cases I use the same datasource from the code behind like this : Edit:
