ok, so yeah, repeater with a radio nested, nice move MS.. i got the javascript to keep the radios from being selected.. each radio button has a list of checkboxes that get show / hide on click of the radio button.. Item -> item details kind of thing

 repeater -> radiobutton -> repeater -> checkboxes

on itemdatabound find the repeater and add checkboxes as necessary

so it all renders fine, and works nicely...

BUT!!! no matter which radio button is checked I always get the value of checked=false on each radio button.  I find the control fine, but it is always false, even when I'm looking at a checked radio... HOW DO I DO THIS!!>> so upset, this has taken me near 8 hours just to get to this point and now its another battle to figure out how to get this... ARRGH!!

RadioButton rb = (RadioButton)subCatListing.Items[0].FindControl("subCatItem");

I've tried a datalist also to no avail.. Oh yeah, and its in a wizard as a wizard step also... :-\

HI, r u assigning different id's  to all radio button's and make sure that u check all the radio Button Id's and not a single one in a loop..

It would be better if u post ur code... 

wow, well first of all thanks for such a quick response.. I never could figure it out.. here's more or less what I was doing maybe it will help someone out there

.net they were all server controls-->
<asp:wizard>
<wizardStep>

<repeater  id=mainCategories>

<asp:radioButton id="subCatItem" />

      <div>
        <repeater id=subCategoryDetails>
          
            <asp:checkBoxList id="chbxSubCatListing">

        </repeater>
      </div>

</repeater>
</wizardStep>
</asp:wizard>

-->C#

//so obviously I left out some code, like casting the dataitem, etc..
//but in the end the idea was to on item bound, get the current radio button assign some attributes to it, onclick to select only one, show/hide the div
//append an id to it, etc...
//bear with me.. but it rendered out exactly what I thought I wanted, a list of radio buttons that show / hid a div of checkbox items

onitemDataBound(sender, itemEventargs e)
{

foreach (var o in jobTypes)
{
if(i == currentItem && currentItem <= totalResults)

var currentSubCategory = from p in ...

}

Now The pain---->

protected int getSubCatValue()

jRequest = {cast to object}

if (subCatItem.HasControls())
{

CheckBoxList cbl = (CheckBoxList)mainCategories.Items[0].FindControl("chbxSubCatListing");

 foreach (repeater Item ri in subCatItem.Items)

{

CheckBoxList cbl = (CheckBoxList)mainCategories.Items[0].FindControl("chbxSubCatListing");

well not to beat a dead horse since I was able to do this with checkboxes and I'm fine with that, but yes, I'm sure that they had different ID's, and from my understanding an "item" being bound in a repeater is not a literal control, ie radiobutton, but a repeaterItem, so when its being bound its treated as an entirely different object and is assigned mutually exclusive ID's due to the nature of the repeater item.. so when doing a findControl, I'm not actually finding the radiobutton, but the placeholder for that radio button, which has its own unique ID and exists in each repeater item. 

So as you can see in the code, I'm looping through the controls of the repeater, which contains 'n' number of controls, all spawning from the initial control, but rendered out as repeater items...and if you mean the actual rendering out of the control, the actual string would be something like ctl00ContentPlaceHolder001Ctl00SubCatItemrb_1, ctl00ContentPlaceHolder001Ctl00SubCatItemrb_2,... and as you can see in the posted code, I was assigning a uniqueId to the id of the control onItemBound...

and just to clarify, rb would come through with their different corresponding values... so I would get rb.text = "text1", then the next iteration through the control list of the repeater would be rb.text = "text2" so I know that I was finding the "individual" radiobuttons in the repeater control list, and would have their values, beyond the fact that I was assigning a different unique Id as the value, I did think it conficting Id's might be a problem... so I don't think that was the issue..

my suspicions are that the wizard control does its own kind of control naming and control management, and when I put a repeater in the mix and a radio button in that repeater, the repeater makes unique RadioButtons, and the wizard makes a unique repeater to do some kind of state management for it to keep track of its children controls, and even though I check the control, the wizard or repeater is not handling or bubbling up the stateEvent of that radio... it knows what it placed on the page, but it doesn't know how to handle the radio button checked event since radio buttons are usually a part of a group, and this usage does seem counter intuitive to the usage or a radio button after all..

 again thank you for taking the time, but really, I'm fine with using checkboxes, it appears that radiobuttons inside of repeaters are not the correct usage of radiobuttons, at least not in my implementation of it... and I'm totally fine with using checkboxes...

Thanks Again!!!

 Hi Folks, I hit this very same issue yesterday. I assumed that I could drag a radio button on to my repeater, set the groupname property and that was it. Of course I quickly saw that it wasn't that easy. How frustrating to have something like this take up hours of my time.

 I searched on google and saw that some people had a solution involving the use of javascript. This just looked plain messy. What if javascript was disabled on my client browser etc. etc. The method I went with was one by Scott Mitchell at 4guysfromrolla.com. Scott's article can be found right here on www.asp.net. The article itself covers the use of radiobuttons in the Gridview but you can apply exactly the same approach to get around the problems of using radiobuttons in the repeater control. Scotts approach is instead of using the asp.net radiobutton server control we add a asp.net literal control to our repeater. Then when we bind our data to the repeater we'll dynamically insert a standard html radio button <input type="radio". In the case of the repeater we'll do this in the ItemCreated event. Bottom line this approach works for me and it doesn't require any javascript:

That solution doesn't require javascript, you're right, but I'm not sure it would work if the grid was nested inside a wizard control... you'd have to add more code to handle the various wizard step state..

also a note to people reading this, most, of if not all of the javascript solutions will not work when a repeater is nested inside a wizard, you can't get the checked value, since when the wizard is loaded, the value is unchecked.. I

However, I'm not sure if the above example will work, definately the best solution worth a try so far.. but again, the way the wizard maintains its state is similiar to the way the gridview does, SOOOO try getting the value of a selected radio button from within a repeater, within a wizard... like I said in my previous post, I was able to get this working using checkboxes, if I'm wrong, I'd love to hear about it!!!
