Web Forms :: RadioButtonList Inside Parent - Items Not Grouped Properly

Feb 10, 2011

I am writing a form which has a set of options (radio buttons), and under each option, there is another set of options. For example:

- Session 1
- New Book A
- Used Book A
- Session 2
- New Book B
- Used Book B

I've tried using HTML <input type="radio", and <asp:RadioButton, but even though I assign the "name" attribute correctly, the buttons are not mutually exclusive -- i.e., you can click both within each group. I see in "View Source" that the name and ID are altered, and therefore become ungrouped by the ASP.NET processing. I've tried using <asp:RadioButtonList, and this works functionally, but the items are not grouped properly. They appear like this:

- Session 1
- Session 2
- New Book A
- Used Book A
- New Book B
- Used Book B

C# - Show Items From Db Grouped By Manufacturer With Group Heading?

Feb 16, 2011

I have a number of products in a SQL2005 DB. I have the Stored Procedure set-up to return the info as grouped rows containing 'manufacturer, model, quantitiy'.

I need to then display this content on a c# Asp.Net 4 web form grouped by manufacturer with the manufacturer as the group header. The whole data should be displayed over a 3 column layout.

So, Ive used a Datalist as this allows for the number of columns to be stipulated.

However, I can't work out an effective way to show the various products groupd by manufacturer, eg as shown below;

Toshiba
3401
3685
3699

Forms Data Controls :: RadioButtonList Inside A FormView?

Feb 27, 2010

In the website I'm building, I have a form that allows new users to register. Part of this page has mandatory address fields, and I use a postcode lookup field which returns a SuburbID and FullSuburbName (Suburb, State & PostCode) to a RadioButtonList inside an UpdatePanel.

[Code]....

I then handle the insert process in codebehind, and all this works perfectly on my New Account page.What I'm trying to do now, however, is replicate this functionality in the Edit Template of a FormView on my Manage Account page. The idea being that the user can view their current details in the ReadOnly view, then switch to Edit view to change their address (amongst other details of course). When the FormView changes to Edit mode, it should display the user's current PostCode in the textbox, and the RadioButtonList should display the available Suburbs for that PostCode, with the user's current SuburbID as the initial SelectedValue. If the user changes the PostCode and hits search, this refreshes the RadioButtonList with the new list of Suburbs, and once they have selected a new SuburbID this should get written back to the DB with the rest of the form (when they click Save I mean), using the SQL Data Source Update element. However, I simply cannot get this to work inside the FormView Edit Template and

So far, I have tried to handle the FormView's ItemCreated event and populate the RadioButtonList with the Suburbs that match the user's current PostCode, but if I do this with SelectedValue='<%# Bind("SuburbID") %>' in the RadioButtonList, I get the error "Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."If I then change it to have the SelectedValue populate from the codebehind, this works on the initial switch to Edit mode, but when the user changes the PostCode and hits search, I get a different error "'rblSuburb' has a SelectedValue which is invalid because it does not exist in the list of items."My thinking was that rather than binding the RadioButtonList I would just add the new SelectedValue in the SQLDataSource_Updating method, but it doesn't seem to like that either.

Web Forms :: Get Selected Value Of RadioButtonList Inside Repeater Control

Dec 23, 2013

I have added a RadioButtonList inside a repeater as follows:

(.aspx file):

<asp:Button ID="Button1" Text="Add Comment" runat="server" />
<asp:Panel ID="pnlPanelDemo" runat="server" CssClass="modalPopup" ViewStateMode="Disabled">
<cc1:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server">
</cc1:ToolkitScriptManager>
<asp:Repeater ID="rptComments" runat="server">

[Code] ....

Now suppose if 3 questions are displayed on the webpage then 3 radiobuttonlists are displayed. I need to send the selected text of radiobuttons separately in my table in SQL Server on a button click event.

Suppose if selected answers are Very Poor, Average and Good then database entry should look like:

1         Very Poor
2         Average
3         Good

(.aspx.cs file)

protected void AddComment(object sender, EventArgs e) {           
string constr = System.Configuration.ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString;
string sqlStatment = "INSERT INTO FeedbackResponse(QUESTION_ID,RESPONSE) values(@QID,@RESP)"; 
using (SqlConnection con = new SqlConnection(constr)) { 
using (SqlCommand cmd = new SqlCommand(sqlStatment, con)) { 
con.Open();  cmd.Parameters.AddWithValue("@RESPONSE",this.rptComments.   
cmd.ExecuteNonQuery();  con.Close();               
} }

I am not sure what to do in the bold line.

Synchronizing Items In RadioButtonList Between Design And Source Views?

Apr 19, 2010

After editing the list of hardcoded items in a RadioButtonList on a ASP.NET page via the Design view, I find that the HTML source for the RadioButtonList still does not update to the latest list of items i.e items are still the ones before the changes.

Is there a way to synchronize what appears in the Design view and the actual HTML source? Or do I have to delete the RadioButtonList and recreate it?

Web Forms :: Delete Directory And 2 Files That Are Inside Does Not Work Properly

Mar 13, 2010

I have a ListBox1 on the Form that I read in the same Directories: "GetS" as in the code below.

Now I select the first index wich is 0 in the listBox with the mouse and press Button1.

What the code below does is to find that specific folder that also contains a .BMP file and a file: File1.txt

So I will first delete the .bmp file and the File1.txt and at last the directory.

My problem is as follows. When I press Button1 the First time, nothing at all was deleted but the second time I press the Button1, the .BMP file and the File1.txt were delete fine.

But the code breaks at this line and says that the directory isn´t empty. But the directory is empty as I can see when open it manually.

So initially my problem is why the .BMP, File1.txt and the directory aren´t deleted at the first press of Button1 ? (ListBox1 has AutoPostBack set to TRUE and everything is put inside an updatepanel)

Forms Data Controls :: Radio Button Inside A Repeater Or RadioButtonList?

Jun 3, 2010

I want to present a list of delivery options to end users which will be in 3 columns - service description, radio button (to select) and then the price of the service. Also I want to auto postback when the user selects a service from the appropriate radio button - e.g. :

[code]....

I have set this up using a repeater control and stand alone radio button, plus literals to display the text elements all within a tabular structure which looks OK. I have actually overcome the issue where by default you can select all radio buttons using the prescribed javascript fixes I found when searching. This way offers me control over the formatting which is important.

However it does not seem that intuitive to pickup the selected value of the radio button this way, especially with the auto postback - I am having issues trying to access the selected radio button to interpret what the user wants.

It would seem much more appropriate for a RadioButtonList but I can't work out how to override the default formatting, and also how to insert extra table columns for the price etc to keep it all nicely formatted.

So either I need to crack the interpretation of the current setup or to find out is there a way to hijack the default setup of the RadioButtonList?

Data Controls :: Fire RadioButtonList / SelectedIndexChanged Event Conditionally For Some Items?

Oct 22, 2013

i read article "using javascript with asp.net radiobuttonlist control" and i found it useful.

[var RB1 = document.getElementById("<%=RadioButtonList1.ClientID%>");
var radio = RB1.getElementsByTagName("input");
if am setting radio[1].checked = 1; the item is checked. ]

step1: radio[0]=checked
           radio[1]=not checked
            radio[2]=not checked

step 2: by using javascript , am changing the selection

now 

           radio[0]=not checked
           radio[1]=checked 
          radio[2]=not checked

step 3: if am changing radio[0]=checked by clicking, it wont fire the selected index change that i wrote on code behind

but if am changing radio[2]=checked by clicking, it will fire the selected index change that i wrote on code behind

My requirement: i want to fire the selected index change in both cases. for that i need to change the selected index in step 2.

Menu Make Parent Items Non-hyperlinks?

Aug 24, 2010

I have an asp:Menu control driven by a web.sitemap file.

For example, the menu is like:

Fruit
- Apple
- Orange
- Strawberry

Color
- Blue
- Red
- Yellow

In the sitemap, the specific fruits are children of the "Fruit" siteMapNode (likewise for the colors) The menu is setup as dynamic so Fruit and Color are static and the specific fruits and colors show up in the popup/flyout menu. The parent items are just for categorization purposes; there's no "Fruit" page.

How do I make it so "Fruit" and "Color" are NOT links?
