TextBox control are already known in GUI Programming. In this article I have highlighted what are the new properties in UWP.
 
 PlaceholderText
 
 This is like tooltip properties, highlighting about what user has to enter in the text box. This is text displayed when the textbox text is empty.
 
 ![tooltip properties]()
 
 TextBox is empty,
 ![Textbox is Empty]()
 
 Enter the value in the textbox, the PlaceholderText is hidden
 
 ![PlaceholderText]() 
 
 
 Header Text 
 
 This Header text property is used for replacement of label control, user no need to  add extra label control to tell about the textbox.
 ![Header Text]() 
 
 
 Clear Button
 
 Each textbox default come with clear button. Let say if a user want to clear the textbox in just one click, she/he can do it using this control placed in the right side  top corner of the textbox,
 
 ![Clear Button]()
 
 InputScope
 
 Input scope property highlight to the user that what characters are needed to enter  the into text box, this property is not validation property.
 
 Example
 
 Set the InputScope = “Number” application handle this property in windows  10 desktop. User can enter any characters into this textbox. Just like Windows 10  mobile, it will show the Number pad.
 
 Note: It is not a validation control.
 
 ![validation control]()
 
 Password
 
 PasswordRevealMode properties are used to highlight the password mode to the user,  it contains the following three properties,
 Peek: Is default value for this property with Peek button.
 
 ![Peek]()
 
 Hidden: Normal password box with char.
 
 ![Hidden]()
 
 Visible: Password char visible to the user.
 
 ![Password char visible]()
