MVC :: DataType For DropDownLists, ListBox, CheckBoxes And RadioButtons?
Sep 21, 2010
When using a DropDownList, ListBox, CheckBoxes, RadioButtons what data type do you suggest to hold the values?Usually the values are 1, 2, 3, etc. It makes more sense to me and usually these are the id's of the items.I tend to use the following:
1) When only ONE option can be selected I amke the property of type INT? (Nullable int). This is for when no item is selected it makes more sense to me to check if it's null then 0. And in most validation frameworks there is a null validator.
2) If MANY options can be selected then I use INT[]. Then I can check for null or count the selections.

I'm fairly new working with Javascript. I'm working on an issue where I have a GridView with multiple Checkboxes and Radiobuttons. A user can check multiple checkboxes and if a radiobutton is selected, a checkbox has to be selected. This scenario is working fine, presently with existing asp.net code. But, I want to automate it using Javascript, so that I could avoid a postback.

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've got a project I'm working on where I need to put a RadioButton inside a ListView, and have them all have the same GroupName. (can't use RadioButtonList, long story).[URL]This works perfectly, but with one small bug which undoubtedly will come back to bite me. If I click one radio button, and then click another while the javascript function is still running and has not completed; I can get 2 radiobuttons in the same group selected.

Again a question about RadioButtons/ RadioButtonList
I've the following Model:
public class SkillLevelModel
{
public long? Id { get; set; }
public int? SelectedLevel { get; set;}
}
I've the following Controller:
public class SkillController : BaseController
{
public ActionResult Index()
{
var skills = new List<SkillLevelModel>();
for (int i = 0; i < 10; i++)
skills.Add(new SkillLevelModel() { Id = i, SelectedLevel = new Random().Next(0,5) });
return View(skills);
}
I've the following code in the View:
<% foreach (var item in Model) { %>
<tr>
<td style="width: 30px" align="center">
<%= Html.Encode(item.Id) %>
</td>
<td>
<% Html.RenderPartial("UCSkillLevel", item); %>
</td>
</tr>
<% } %>
I've the following code in the PartialView:
<% for (int i = 0; i <= 5; i++) { %>
<td align="center">
<%= Html.RadioButton("SelectedLevel", i, new { id = Model.Id + "_" + i })%>
</td>
<% } %>
The problem is that no radiobutton is checked, althought they have a level.

I have a table called "question" which consists of various columns, including 3 columns of type: bit.
these columns are: yes, no, maybe.
The corresponding viewmodel has 3 properties of type boolean. The controller returns the views, which are based on the viewmodels.
By default MVC create checkboxes for boolean types, the thing is that the properties have to be related, only 1 should be checked at a time. That is why I want to change the checkboxes to radiobuttons.
After some search on the web I tried various things, in the end I got the create working by putting three radiobuttons, tied to the same boolean field, adjusing the values.
But how to edit a question? The view is filled with data from the database, putting 1 of the 3 booleans to true.
What should my view be like, to display 3 radiobuttons, mapped to the 3 boolean types?
techniques used:
MVC 3 RC 2 with razor
Entity Framework 4 (CTP 5)

I am designing a program that will let me enter the name of an item to swap and adds the swap to an array list when a button Add is pressed. Once the item is added to the array list a Sub Procedure should be called which displays the contents of the array list in a list box.
The system will also allow me to remove items from the array list using a Remove button
followed by updating array list.
I have done some part which puts item into the listbox1 which i named lstSwapList.I would need some assistance on the Sub Procedure to display the Value or Description on the other listbox2 which i have also named lstContent,if a value is selected from the listbox1.
I would also want to know how to update the Listbox content,However i hv added a sample of the way i guess it may be.
Any complete solution from anybody on the Sub Procedure and the Update Swap procedure will be greately appreciated.
The script below is what i have done so far.
Partial Class _Default
Inherits System.Web.UI.Page
Protected Sub lstContent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstContent.SelectedIndexChanged
End Sub
Protected Sub lstSwapList_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lstSwapList.SelectedIndexChanged
End Sub
Protected Sub btnAddSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAddSwap.Click
Dim SwapValue As String = "Sixty Pounds"
Dim Counter As Integer = 8
Dim SwapN0 As Integer
lstSwapList.Items.Add(SwapValue)
lstSwapList.Items.Add(Counter)
lstSwapList.Items.Add(New ListItem("300", "1"))
lstSwapList.Items.Add(New ListItem("ASP.Net", "2"))
lstSwapList.Items.Add(New ListItem("Programming", "3"))
SwapN0 = lstSwapList.SelectedValue
For Counter = 0 To -1
SwapN0 = lstContent.Items.Count
Next
End Sub
Protected Sub btnDeleteSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnDeleteSwap.Click
lstSwapList.Items.Remove(lstSwapList.SelectedValue)
End Sub
Protected Sub btnUpdateSwap_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnUpdateSwap.Click
End Sub
End Class
=======================================
Sub UpdateSwap(ByVal valueA As String, ByVal ValueBAs String, ByVal ValueC As Integer, ByVal ValueD As Date)

I have two list boxes, one has a list of available users (about 1500 items) and the other is blank. There is a button to add the seleted items from the first list box to the second one. Both of these listboxes are within an update panel and for some reason it takes over 20 seconds for the items to show up in the second listbox.
Is this normal? Is there an alternate, faster way of doing this?

I have been tinkering around with what should seem a pretty straight forward task even for a jQuery newb as myself.
I have a radiobuttonlist control bound to a collection:
<asp:RadioButtonList ID="radBtnLstPackageSelector" runat="server"
CssClass="PackageS">
</asp:RadioButtonList>
My form does have several other controls of the same type; Now, the challenge is to select and wire up a on Click event for every radiobutton from the radBtnLstPackageSelector.I have tried several approaches such as:
var results1 = $(".PackageS").children("input");
var results1 = $(".PackageS").children("input[type=radiobutton");
var results1 = $("table.PackageS > input[type=radiobutton");

I have a group of radiobuttons. The field they are 'bound' to is of datatype tinyint (sql server), byte .NET. It is set to NOT accept nulls in the database column (col1) and no default value has been set for the column, or indeed, anywhere else.View code as follows:
<ul> <li><%= Html.RadioButton("col1", "1")%></li> <li><%= Html.RadioButton("col1", "2")%></li> <li><%= Html.RadioButton("col1", "3")%></li></ul><%= Html.ValidationMessage("col1", "*") %>
If the user doesn't select any of them, I would expect null to be that the model would attempt to insert into the database. I would therefore get a validation error that I can display to the user, prompting them to choose one of the options.owever, instead of null, the model inserts a 0 into the database. As this does not fail, no error is raised. Can anyone think why? Blowed if I can.I am not setting the default value to 0 anywhere, not in the mvc app or the database

I'm inserting controls dynamicaly on my page on pre-init, thease controls are inserting based on a dropDownList that load its values from a database. These values are diferent to all clients.
If I insert my controls on pre-init then I have access to the value of radiobuttons, but this insert only 1 controls cause in pre render I don't have the selected value of dropDown.
If I insert my controls on on-load event then I have the value of my dropDownList control so I can be able to inser the correct number o controls but I don't have the value of my auto-postback radioButtons.
I make a project to solve this and I share the code of it here. (VB.Net 4.0)

i am pretty new to asp.net. i have a little bit of MIS background so i understand the basics of programming. I went ahead and purchased an ASP.NET book and i understand everything. Right now i am creating an application for a doctor. I have created the database behind it but my problem is that i dont know how to INSERT data into the databases from textboxes, radiobuttons, checklists etc i know how to query, modify, delete data but i am stuck on how to insert
In the beginning of the deployment the database will be empty since the doctor wont have any patients. Just to give you an idea how it will look, the first text box will ask for the patient's name, the second for their telephone number etc

I have used an Update Panel, and place two RadioButtons in Update Panel.
Radiobutton1 ID="radio1" and RadioButton2 ID="radio2"
Then I have set AsynPostBack for Both radioButton's.
Now, on Page Loads radio1 will triggered and fetch all data from Database, then when I click on radio2 it will triger and fetch all data, but if I again click radio1 It doesn't get trigger.
Same process I have done by setting PostBack on both Radiobutton's but show's same result.
