Question

i have this part of code: (in the click event of a button)

           foreach (RadioButton rb in grbFiltro.Controls.OfType<RadioButton>())
       {
           if (((RadioButton)rb).Checked)
           {
               switch (true)
               {
                   case rbt1.Checked:
                       //do something
                       break;
                   case rbt2.Checked:
                      //do something
                       break;
                   case rbt3.Checked:
                        //do something
                      break;
               }
           }
       }

but there´s a error converting radiobutton to string in —> case rbt1.Checked

how do i fix this, or what else can i use?

Answer 1

var rb = grbFiltro.Controls.OfType<RadioButton>()
             .SingleOrDefault(rb => rb.Checked.GetValueOrDefault()) as RadioButton;

if (rb!=null)
    switch (rb.Name)
           {
               case "button1":
                   //do something
                   break;
               case "button2":
                  //do something
                   break;
               case "button3":
                    //do something
                  break;
           }
