RadioButtons, ListViews, And Grouping?
Feb 2, 2010
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.

I want 4 listviews displayed as follows:-
Listview1 Listview2
Listview3 Listview4
I want two on the top and 2 on the bottom inline with the top ones, I use float left and float right for listbox 1 and listbox 2, but using this on 3 and 4 gets them all on same horizontal line if room, I think to use float for listview 3 and listview 4, needs a new parent to align themselves just under the first two, but do not know how to do that ....

I am a longtime .NET developer but for big applications and services. This is my first asp.net project and I have chosen MVC. I have a need for nesting a ListView within a ListView. In this simple catalog app, I have EF 4 Entities that are Categories, SubCategories, ItemTypes, and Items.
My goal is to display a 5 column layout of SubCategories with their ItemTypes below them in a ViewPage. I did just fine with it done out in C# as server directives such as:
[Code]....
But now I would like to do it with nested listviews and I am having trouble with binding in the inner listview. Here is what I have so far:
[Code]....
The bolded line is bogus, of course. The listview won't accept a declarative datasource in this situation. How do I bind to the ItemTypes of the outer SubCategory?Also, I understand there is no code-behind file and I accept that this is because all logic should be in the controller. But does that leave me with the inline binding shown above for the outer listview?
<%
SubcatList.DataSource = Model.SubCategory;
SubcatList.DataBind();
%>
Or is there a more elegant way that doesn't involve an inline server directive?

I am wondering... is it possible to drag and drop items between 2 listviews.
I was thinking of an alternative Instead of using conventional duallistboxes.

I suddenly met a problem with nested ListViews with custom DataSources and DataPagers per each inner item.The original task looks like this. But for the independence from the data sources, I have made an essential example:
Markup:
[Code]....
Code-behind:
[Code]....
Well, the result is discouraging! The DataPagers don't work as appropriate:Try to go to the second group of pages (ex, page #6) manually, and then click on page #7 at the same Pager. You will accidentally appear at page #3!While at the same #6 page, click on page #10. Nothing will happen!Next/Last buttons not work at all!Previous button acts the same as First button!What could be the reason of such a strange DataPagers behavior?
Or, is there the better way to create nested ListViews each with it's own paging?

I am upgrading a website project from asp.net 3.5 to 4.0. I went through the upgrade wizard and site compiled and built fine. But immediately I have encountetred a problem.I have 3 nested ListViews all using the ItemCommand event. Under 4.0 once the ItemCommand event has fired on the inner ListView it then bubbles up and fires on the parent and finally the grandparent.This is a change in behaviour from 3.5 where only the inner ListView event fires. While I can code round this I am worried about these subtly changes between the two versions.

I am having a problem with finding the innermost ListView of a triple nested ListView. The middle ListView has a LinkButton whose event is handled by the outermost's ItemCommand. In the ItemCommand I want to find the third, innermost ListView and set its datasource. How can I find it?

I want to display 2 levels of listview, where outer listview has a datapager with 1 inner listview per page. The code is:
[Code]....
Then I bound outer listview with data in page_load(), which will invoke ExerciseBound(). It work fine for 1st page. The code is:
[Code]....
When I click on 2nd page, it will invoke ChangeExercise(). The code is:
[Code]....
Suppose it will invoke ExerciseBound() again and display 2nd listviewitem, but it fails to invoke ExerciseBound(). I change ChangeExercise() to
[Code]....
But PagePropertiesChangingEventArgs does not contain ListViewDataItem. Any thought? Is there a way to save ListViewDataItem in ExerciseBound() so that it can be accessed in ChangeExercise()? Or is there other way to access ListViewDataItem from ListView class directly?

I have around 5 SQL queries that are returning datasets to my VB.NET application, the queries could be any number not just 5. I have a listview already on the page and all the queries will return the same exact data types (just different numbers). How can I create a listview in the code behind for each one? Or what would be my other options to load up all the results

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)

If I have a list of radiobuttons like this:
[Code]....
, when submitting the form and return the untyped View again, the selection is lost. What is the best practise to overcome this in MVC?
My submit-action looks like this as I am also passing an uploaded file...

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

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 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.
