Determining which radio button is selected

[andycruce]

I have created radio buttons at run time to select a particular file to access. The code is:

            System.Windows.Forms.RadioButton[]
                rb = new System.Windows.Forms.RadioButton[fileNamesSaved];

            for (int i =0; i < fileNamesSaved; i++)
            {
                rb[i] = new RadioButton();
                rb[i].Text = fileNames[i];
                rb[i].Location = new System.Drawing.Point(10, 10+i * 20);
                rb[i].Click += new EventHandler(rb_clicked);
                this.Controls.Add(rb[i]);
            }
            test = 0;
        }

        private void ReturnToBaseForm_Click(object sender, EventArgs e)
        {
            Form1 f1 = new BaseForm.Form1();
            this.Hide();
            f1.ShowDialog();
        }
        private void rb_clicked(object sender, EventArgs e)
        {
            // need something in here to get the text associated with the particular button that was clicked.
        }

The radio buttons are properly created and all use the rb_clicked event handler. What I want to do is to extract the text associated with the button that was clicked. If I look at sender in the debugger the text is there but I don't know how to extract it.

I appreciate any help - have tried a number of possible way to do this but none of them worked

Put a breakpoint on the closing bracket of the clicked handler. Start debugging and click on a radio button. When the breakpoint hits look at the sender variable and notice its type (it should be a radio button). If it is that type you just need to cast the sender variable into a radio button to access its Text property.
