Solution 1

All you have to do is set RadioButton.Checked = true in the DropDownList.SelectedIndexChanged event handler for your corresponding controls. To find out which index is selected, just check the DropDownList.SelectedIndex property.

Solution 2

In DropDown.SelectedIndexChanged you have to place the code of radiobutton1.Checked=True. But before that you have to set autopostback= True for DropDownlist.

Hope this can help You.
