Preserve datalist data on load event in c#

I have datalist containing radio buttons and check boxes. If I select some of them and then redirect to another aspx page. when I come to previous page the radio buttons and check boxes in datalist must be selected. I have selected data in session variable. How to do this using c#.

From stackoverflow

• Using the ItemDataBound event I would retrieve the radio button and compare it's value to your Session variable

  something like this:

  protected void MyDataList_ItemDataBound(object sender, DataListItemEventArgs e)
  {
      RadioButton myRadioButton = e.Items.FindControl("myRadioButton") as RadioButton;
  
      if (myRadioButton == null) { }
      else
      {
          if (string.IsNullOrEmpty(Session[myRadioButton.Value])) {}
          else myRadioButton.Checked = true;        
      }
  }
  

  hunter : After reading your comment you might want to add in the proper control server-side. It would be a lot cleaner. In my example you could just use a switch statement on your inputType type and create and add the proper control to the Item.
