ASP List with Radio buttons

[iam_clint]

Alright I have a page that I have multiple radio buttons being drawn to the page reading from the database. Example

Permissions
Google - ( ) on (x ) off
Nvidia - ( ) on (x ) off
Newegg- ( x) on ( ) off


Google, Nvidia, and Newegg are in a table and it also includes a site id such as
site_id, site_name
1, newegg
2, google
3, nvidia


Another table with user permissions in it
user_id, site_access
1, 1
1, 2
1, 3
2, 2
3, 1
4, 2


I am currently attempting this with a repeater, It writes the radio buttons to the page beautifully.

<asp:Repeater runat="server" ID="sites">
                                        <HeaderTemplate></HeaderTemplate>
                                        <ItemTemplate>
                                        <tr>
                                        <td style="width: 190px; height: 21;" class="member_textlabel"><%#Container.DataItem("site_name")%></td>
 
                                        <td style="height: 21px;">
                                        <table cellpadding="0" cellspacing="0" style="width: 170">
                                            <tr>
                                                <td style="width: 24px">
                                                <asp:RadioButton  runat="server" GroupName="site_access" ID="site_on" /></td>
                                                <td class="member_textlabel" style="width: 41px"><%#Container.DataItem("site_id")%>
                                                On</td>
                                                <td style="width: 20px">
                                                <asp:RadioButton  runat="server" GroupName="site_access" ID="site_off" /></td>
                                                <td class="member_textlabel">
                                                Off</td>
                                            </tr>
                                        </table>
                                        </td>
                                        </tr>
                                        </ItemTemplate>
 

But i cannot figure out how to read these radio buttons server side.

so first thing it needs to put checkboxes in the proper places and next it needs to be able to be modified such as changing the radio button configuration and hitting a save button. So i need to do this in a way i can know what site_id's are on and off server side.

Are you doing this as an exercise to learn how to use repeaters?
There is an easier way to do this ...

Anyways, you need to use the FindControl method to retrieve the RadioButton from the repeater and then check it's value.

C#:

RadioButton rdo = (RadioButton)myRepeater.FindControl("rdoID");

VB.NET

Dim rdo As RadioButton = DirectCast(myRepeater.FindControl("rdoID"), RadioButton)

no by all means if there is a different better way to accomplish this let me know.. I am fairly new to asp.net and .net in general.

On a side note I'm not sure how to give each radio button a unique id then be able to grab it in the code because this is all database driven. Is there a way to grab an array of the radio buttons?

[Frinavale]

When you talk about grabbing an array of RadioButtons, are you talking about client side or server side.

A RadioButtonList is basically an array of RadioButtons. It's better to use RadioButtonList s in your solution instead of individual radio buttons....main ly because it's hard to set unique IDs for individual radio buttons.

I think using CheckBoxes instead of RadioButtons is probably going to be easier for you in the long run...because then all you have to do is check whether or not the CheckBox has been selected, rather than checking which RadioButton is selected.

Are you not using a GridView because of the overhead costs?

[iam_clint]

i'm not using gridview because i've been using .net for about 3 weeks.
Yes this page wasn't my design but if I absolutely have to I can change it to checkboxes can you give me a small working example please, content is dynamic.

@iam_clint
Give me a bit and let me see if I can't get something running :)

Are you displaying the site permissions for a single user or for all users at a time?

<edit> oh and what .NET framework are you using?</edit>

[iam_clint]

.net version is 3.5

its single user at a time.. the dynamic things are just the sites and their id's

Thanks for the help i've been messing around with it to no avail

[Frinavale]

I'm sorry but I got pulled into a meeting for most of the day and wasn't able to look into this.

I've got an idea for a solution though :)
Using an ItemTemplate and GridView.

I'll give it a whorl tonight
