The DropDownList Default Value is Not Selected in Edit Mode when using IE.

With the code below:

  • - Display the page in IE 8
  • - Double Click the WebGrid Row 1, Column 1, Priority to change to Edit Mode
  • - A DropDown List is displayed however UNDECIDED is not selected
    • With other Browsers such as Mozilla it is selected
    • The stand alone DropDown List above the WebGrid has it selected
