Radiobuttons added on pageload....

Question

Hi,
I've got a page where a list of radiobuttons are added during run time, I need to take some action on a button click(also added on runtime) depending upon the selection made...

How do I achieve this???

Try this code sample public void AddRadioButtons ( ) { RadioButton rBut1 = new RadioButton ( ) ; rBut1. Location = new Point ( 50 , 50 ) ; rBut1. AutoCheck = true ; rBut1. Text = "Checked" ; rBut1. Checked = true ; rBut1. CheckedChanged += new EventHandler ( rBut_CheckedChanged ) ; Controls. Add ( rBut1 ) ; RadioButton rBut2 = new RadioButton ( ) ; rBut2. Location = new Point ( 50 , 80 ) ; rBut2. AutoCheck = true ; rBut2. Text = "UnChecked" ; rBut2. Checked = false ; rBut2. CheckedChanged += new EventHandler ( rBut_CheckedChanged ) ; Controls. Add ( rBut2 ) ; } private void rBut_CheckedChanged ( object sender, System . EventArgs e ) { if ( sender is RadioButton ) { RadioButton radiobutton = sender as RadioButton; if ( radiobutton. Checked ) { radiobutton. Text = "Checked" ; } else { radiobutton. Text = "UnChecked" ; } } }

Hi Try this code if (TextBox2.Text != string.Empty) { int rbCount = Convert.ToInt32(TextBox2.Text); RadioButton[] radioButtons = new RadioButton[rbCount]; for (int i = 0; i { radioButtons[i] = new RadioButton(); radioButtons[i].GroupName = "rb"; radioButtons[i].Text = Convert.ToString(i); PlaceHolder1.Controls.Add(radioButtons[i]); } } Radio Button List: if (TextBox2.Text != string.Empty) { int rbCount = Convert.ToInt32(TextBox2.Text); RadioButtonList rbList = new RadioButtonList(); for (int i = 1; i { rbList.Items.Add(new ListItem(Convert.ToString(i), Convert.ToString(i))); } PlaceHolder1.Controls.Add(rbList); }
