Detecting which radio button is clicked.

[Chris]

Hi,
I have a Radio button group on my page as part of a form . How do i detect which of the radio buttons has been selected in the server side code.? Is there an easier way than testing each button to see if it is checked?

<telerik:RadButton ID="NordicInclBtn" runat="server" GroupName="NordicsGroup" Checked="true"

Skin="Office2010Blue" Text="RadButton" ToggleType="Radio" AutoPostBack="false">

<ToggleStates>

<telerik:RadButtonToggleState Text="Include" PrimaryIconCssClass="rbToggleRadioChecked" />

<telerik:RadButtonToggleState Text="Include" PrimaryIconCssClass="rbToggleRadio" />

</ToggleStates>

</telerik:RadButton>

<telerik:RadButton ID="NordicExcBtn" runat="server" GroupName="NordicsGroup" AutoPostBack="false"

Hello Chris, 

if you do not want to use loop then take one hiddenfield and when you checked any radio button at that time you can store their value/id in this hiddenfield and in server side using hiden field you can get the information about selected button.

OR

List<RadButton> lbtn = (from r in this.form1.Controls.OfType<RadButton>() // (from r in this.Controls.OfType<RadButton>()
                                    where ((RadButton)(r)).Checked == true
                                     select r).ToList();


            if (lbtn.Count > 0)
            {
                Response.Write(lbtn[0].Text);
            }

Thanks,

HI,
I openned a support ticket and they suggested a slightly different approach whic i have adjusted to suit my needs.
I placed each button group in a placeholder and gave each button a command name. Now i can have multiple toggle button groups and when the form submit occours i just call the following method passing the placeholder and in return i get the CommandName of the checked button  -:

protected String GetCheckedCommand(PlaceHolder holder)

        {

            foreach (Control btn in holder.Controls)

            {

                RadButton rb = (RadButton)btn;

  

                if (rb.Checked)

                {

                    return rb.CommandName;

                }

            }

  

            return null;

        }

Hope tihis helps people.

Chris
