GroupingName appears to be a class, so it can be anywhere in the application.
local represents a namespace and will be defined at the top of the xaml.

Solution 1

You need to place this in <Window.Resources>. This also assumes you have created a namespace called local in your window that refers to the namespace that holds your class . Something like this

XML

<Window x:Class="yourClass.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window1" Height="300" Width="300"
        xmlns:local="clr-namespace:Models;assembly=Models" >
    <Window.Resources>
        <local:GroupingName x:Key="GroupingName"/>
    </Window.Resources>
    <Grid>

    </Grid>
</Window>

Hope this helps

By the way

There is no such thing as a stupid question. Only stupid answers. Rather just ask :)

thank you very much for replay but when i write in user.control resources vs gives exception: The type 'local:GroupingName' was not found.

Did you declare the namespace of your class in your USerControl declaration

xmlns:local="your namespace which contains GroupingName" ?

Im trying to do that. My user control name is logistic and Grouping Name is inside logistic and project name is H_Pro. how i can declare it? sorry for such questions....

Sorry, got stuck in a meeting. You need to check at the top of your xaml file, and you will see something to the effect of x:Class="something or other". Just type xmlns:local= and a popup should display showing various namespaces to choose from. Choose the one that corresponds to the Class declaration at the top.
