how to deactivate a specific control while page loading

Question

Peace upon you 

i have a "SearchBox" control, i have implemented "SuggestionsRequested" event.
when i open the application, the searchbox is the first control to be activated and it shows suggestions.

like this:

all what i need is to make this searchbox and suggestions deactivated until users put the pointer of the mouse inside the "searchbox"

thanks in advance :)

Answer 1

You should set the initial focus to a different control.

You don't want to actually disable the control. That will prevent the user from tabbing to it later.

Answer 2

Thanks Rob , i made it  

i put this block of code into the constructor of the page

   
 base.Loaded += (s, e) =>
            {
                TextBox.SelectAll();
                TextBox.Focus(FocusState.Programmatic);
            };

TextBox: refers to another control 
so my searchBox will not be on Focus state
