Vista - "User Control" and Namespaces

How can I define a Namespace for User Contols?

I still a XAML newbie but I think the following is correct.
Is the following what you are looking for?

The format for namespace definition (in a XAML file) is:

[A] xmlns:custom="clr-namespace:SDKSample;assembly=SDKSampleLibrary"

If you have an external assembly of WPF controls
[1] "My_ctr_lib.dll"
with a custom public button type
[2] "My_button"
and wanted to use the XAML namespace prefix
[3] "Ctr_nsp"
to prefix the custom control references.

The XAML namespace defintion is:

[A] xmlns:Ctr_nsp="clr-namespace:My_control_nsp;assembly=My_ctr_lib"

Or:

xmlns:[3]="clr-namespace:[2];assembly=[1]"

Now that the namespace is visible (in XAML code) you can use it with
(1) Object element syntax and (2) Attribute syntax.

To instantiate the control (now that its defined) you

<Ctr_nsp:My_Button Name="My_button_instance">
Button Label
</Ctr_nsp:My_Button>

Note that if your control namespace is IN the same assembly with your
application then you can omit the "assembly=[1]" portion which would yield.

xmlns:[3]="clr-namespace:[2];"

Or:

[A] xmlns:Ctr_nsp="clr-namespace:My_control_nsp;"

If anyone can find a problem with this please let us know :-)

PS. I haven't done this yet but I need to know this.

As soon as I posted this I noticed an error - the correct answer is:

If you have an external assembly of WPF controls
[1] "My_ctr_lib.dll"
with a CLR (C#,VB,etc) namespace of
[2] "My_control_nsp"
with a custom public button type
[3] "My_button"
and wanted to use the XAML namespace prefix
[4] "Ctr_nsp"
to prefix the custom control references.

The XAML namespace defintion is:

xmlns:Ctr_nsp="clr-namespace:My_control_nsp;assembly=My_ctr_lib"

Or:

xmlns:[4]="clr-namespace:[2];assembly=[1]"

To instantiate the control:

<Ctr_nsp:My_Button Name="My_button_instance">
Button Label
</Ctr_nsp:My_Button>

If your control namespace is IN the same assembly use:

xmlns:[4]="clr-namespace:[2];"

Or:

xmlns:Ctr_nsp="clr-namespace:My_control_nsp;"

Sorry about the mistake in the previous response!

Hi Shawnk

Thanks not what I wanna do.
See my Attached Solution

There a two controls:
One Custom Control with NameSpace:
Namespace Controls
Public Class MyCustomControl
Inherits System.Windows.Controls.Grid
End Class
End Namespace
And one UserControl
And how can I keep the UserControl in a NameSpace?

Horst

Hi Shawnk

Thanks to explane these basic things.
But in the future the Designtool MS Expression Blend will handle this
declarations.

Best regards
Horst

Hi Horst



Try with
<UserControl x:Class="Controls.MyUserControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid>
</Grid>
</UserControl>

seems generic.xaml is not matching to the rest of the example so I
commented out this.

I hope this works then
it successfully compiled


see you in coffee room

Hi Horst

try this:

<UserControl x:Class="Controls.MyUserControl"

xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Grid>

</Grid>
