I'm trying to validate to that 1 of the 2 radio buttons must be selected. You can't pass the GroupName of your control and expect it to find anything. The IDs of your radiobuttons are rdOption1 and rdOption2. Those are the strings you can pass to FindControl.

I understand what your saying. This will validate if the radio button rbOption1 is selected. But, I'm trying to validate if 1 of the 2 radio buttons are selected than it would be valid.

That's why I was trying to use the GroupName. Is there a way I could validate these 2 radio buttons at the same time to ensure 1 of the 2 options are selected? Thank you your second code works great!

Mar 20,  · JavaScript function to validate Group of RadioButtons (Multiple RadioButtons) in usloveescort.com When the Submit Button is clicked, all the RadioButtons inside the Table are referenced using the Tag Name. Then using FOR loop, each RadioButton is verified whether it is checked. If one RadioButton is checked, then the validation is successful else an error message is displayed using . The trick is to use an expression (first parameter to usloveescort.comuttonFor) which contains a value that changes per group of radio-buttons. In your case, it would be an index in the list of questions. Here is some sample code.

If you want multi-select, use checkboxes! NET developers need to be aware of. If you use ASP:RadioButton controls on your WebForm, then you know that in order to get them to behave properly, that is, to define a group in which only one of them can be selected by the user, you use the Group attribute and set the same value on each one.

For example:. BUT, if you user server-side code to manipulate the Checked attribute of these controls, it is possible to set them both to believe that they are checked.

As long as you remain in server-side code, the system will believe that both radio buttons are checked you can verify this in the debugger. Therefore, if you later have code that looks like this. The good news is that if you return to the client with multiple radio buttons checked, the browser tries to clean that up for you and make only one of them really checked.

It turns out that the last one on the screen wins, so in this case, you will in fact end up with rdo2 as checked, and if you then make a trip to the server to run the code above, it will appear to be working properly. And this gets even uglier if you ever set these radio buttons to be disabled. In that case, although the client browser renders the radio buttons as though only one of them is checked the system actually retains the value of both of them as checked, and your next trip to the server will really frustrate you because the browser showed rdo2 as checked, but your DoSomething1 routine keeps getting executed.

After you copy the markup and page-behind code into the appropriate files. Use the Blank Postback button to cause a postback to the server so you can inspect things without making any changes. The moral of the story is: if you do server-side manipulation of the Checked status of RadioButton controls, then you need to set ALL of the controls in a group whenever you want to change one.
