Q:

resizable Custom Window in WPF

I am needing to make a custom window with WindowStyle. None, AllowsTransparency = true, etc. 
and  "resizeable" 
how con help me to create resizeable this? 
tanx...

A:

The most simple solution is to implement the ResizeMode property, setting it to "CanResizeWithGrip". 
<Window x:Class="TestProject. ScratchWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
        Opacity="1.0" 

        ResizeMode="CanResizeWithGrip"

        WindowStyle="None" 
        AllowsTransparency="True"
        Title="Test Window">

    <!--  Window Contents Here -->
</Window>
