Looks like you are trying to assign a Radio Button checked or not-checked.
StatusRadioButtonList.Text = "Selected value";
StatusRadioButtonList.Checked = true;
if (rdoStatusRadioButtonListA.Text.ToString().Equals("One"))
{
rdoStatusRadioButtonListA.Checked = true;
}
else {
rdoStatusRadioButtonListA.Checked = false;
rdoStatusRadioButtonListB.Checked = true;
}
Let me know if this answer doesn't solve your problem. I will provide in much detail.
