  Unknown attribute Name on element

  Oct 25, 2008 11:26 PM | LINK

  Hi

  I did download an example ( http://silverlight.net//samples/sl2/imagesnipperv2/source/Source_ImageSnipper_CS.zip) and tried to change the namespace to another name. After doing the program stop working

  Now I just remove a lot of the code and files and left with some simples project .

  I'm still getting  " Unknown attribute Name on element " error

  The strange thing when I compile i don't see any compilation errors, but i see the error at run time or just when I open the page.xaml file

  <ctl:Button x:Name="testName" ></ctl:Button> is the line that does make the error  

  I have the following files and content

  Page.xaml

  <UserControl x:Class="TestMenue.Page"

  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

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

  xmlns:ctl="clr-namespace:TestMenue"

  Width="400" Height="300">

  <Canvas x:Name='root' Width='800' Height='600' Loaded='root_Loaded'>

  <ctl:Button x:Name="testName" ></ctl:Button>

  </Canvas>

  </UserControl>

  Re: Unknown attribute Name on element

  I dont know why you have the Button there, but it seems that there is also a Button Control inside Windows.Controls. Do you want to use that? Or you want to use your own one? If so, you can add the existing Button from Windows.Controls first, and edit a template inside Blend. In such case, all the event and properties are remained to be inherited in your new developed Button.

  Can I answer you question? It seems I made things more messy
