Did I already explain you that you should not create your radio buttons in Designer? It makes no sense — manual unqualified boring unreliable work. Create them in code instead:

C#

RadioButton[] RadioButtons = new RadioButton[/*...*/];
for (int index = 0; index < RadioButtons.Length; ++index) {
    RadioButton rb = new RadioButton();
    RadioButtons[index] = rb;
    rb.Text = //... from some data file, resource, date set...
    rb.Left = //calculate it based on index and/or layout measures
    rb.Top = //calculate it based on index and/or layout measures
    rb.CheckedChanged += (sender, eventArgs) => {
        RaduoButton radioButtonSender = (RaduoButton)sender;
        //some handling using radioButtonSender and its status
    };
    rb.Parent = someRadioButtonParent; //some group or panel
}

If you do this, all operations become easy:

C#

for (int index = 0; index < RadioButtons.Length; ++index) {
    RadioButton[index].Text = dr[index];
    //...
}

Solution 2

Try to use FindControl.

C#

for (int index = 0; index < 200; index++) 
{
Control radioButton=yourContainer. FindControl("RadioButton"+i);
if(radioButton!=Null){

radioButton.Text= dr[i].ToString();

}

}
