Combo box displaying the project name after binding

Question

Hi Everyone,

 

I have a combo box which i have bind the items reading from the database. now i have added the style to the combo box by doing the following;

(right click combo box ->Edit Template -> Edit Copy and i have applied to the combo box.)

 

this was my default text in my combo box 

my default text on the combo box was  (--Please Select Company Name--)

 

After that my default text doesn't appear anymore and  it is showing the name of the project inside the combo box and my name of the project is this one;

<Page WindowTitle="Registrations" x:Class="UserInfor_Enrollment.Registrations" >

 

Please help on how can i solve this. I tried to remove it and i got this error below 

Error 1 'Page' root element requires a x:Class attribute to support event handlers in the XAML file. Either remove the event handler for the Unloaded event, or add a x:Class attribute to the root element. Line 9 

 

Thanks.
