Loop through controls of a UserControl

Question

I have a user control with 5 simple radiobuttons, I need ot loop through those in code-behind, but I am drawing a huge blank on how to do this. Can someone help please

Answer 1

foreach (var ctl in this.Controls)
{
    if (ctl is RadioButton)
    {
       // stuff
    }
}

Note that this is not recursive. If your radiobuttons are further down in the control container heirarchy, you'll need to write a recursive method to find them. See my old answer here for an example of a recursive FindControl function.

Answer 2

Just guessing here, but if you are trying to have a group of related radio buttons, you shouldn't be using individual radio button controls, but a RadioButtonList control. This will hold all of the radio buttons in a group and allow you to iterate over them.
