How Can I Check The Selected Values Of Multiple Radiobuttonlists?

Question

I have a HTML form that has multiple RadioButtonLists.

Solution 1:

I've done similar things before (namely, manipulating different validator controls). Here's how I'd do it:

var radioButtons = newList<RadioButtonList>() 
{
    RadioButtonList1,
    RadioButtonList2,
    RadioButtonList3,
    RadioButtonList4,
};

foreach(RadioButtonList rbl in radioButtons) 
{
    if (rbl.SelectedValue == "1")
    {
        value1++;
    }
    elseif (rbl.SelectedValue == "2")
    {
        value2++;
    }
}

You can define the list of RadioButtonList as a private field within your ASP.NET page or user control

Solution 2:

If you put all RadioButtonLists inside a DIV with runat="server" you can easily loop through only RadioButtonLists inside of that DIV. Here is a simple example that is triggered on Button1 click, you can put a debug point at the end of Button1 click event to see the value of value1 and value2.

protectedvoidButton1_Click(object sender, EventArgs e)
    {
        int value1=0, value2=0;

        foreach (Control c in myradiolist.Controls)
        {
            if (c is RadioButtonList)
            {
                RadioButtonList rbl = (RadioButtonList)c;

                if(rbl.SelectedValue.Equals("1"))
                    value1++;

                if (rbl.SelectedValue.Equals("2"))
                    value2++; 
            }
        }           
    }
