Hi Imar,

in the "How it works" on Page 472 (chapter 13 - Display and updating data) you say that "VS knows that in order to get the selected value from the DropDownList it should access its SelectedValue property, so it adds that as the PropertyName for the ControlParameter".

Unfortunately, if I press F4 to open up the properties grid of the DropDownList, I cannot find the SelectedValue property.

Is it a hidden property ?

Thank you

Hi there,

It's not hidden, but it's read-only. Therefor, you can't set it at design time using the Properties Grid, but only use its value at run-time. If you type something like DropDownList1.SelectedValue in IntelliSense in the Code Behind you'll see the property appear.

Hope this helps,

Imar
