Hello,

Which version of Silverlight are you using?  If you are using Silverlight 2 beta1, I think it's not possible to access the content of button from Javascript.

the code is simple:

button.width = XXX;

or just show it by:

alert(button.width);

that works, but i can not get the "content" property.

For example:

The following is Page.xaml in Silverlight 2 project.  

<UserControl
    xmlns="http://schemas.microsoft.com/client/2007"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    x:Class="RET.Page"
    Width="640" Height="480">

    <Grid x:Name="LayoutRoot" Background="White" >
      
        <Button x:Name = "myBtn" Content="Button1" />
       
                  
    </Grid>
</UserControl>

Are you saying that you are able to get the width of "myBtn" one from Javascript?

For example:

function JSFunction(){
 
      myBtn.width = 10;

} 

I don't think it would work. If it works, it's something new for me.

on the default test page, my javascript function is like

<script type="text/javascript">
    function ChangeButton()
    {
      var ajaxCtrl = document.getElementById("xaml1");
      var button = ajaxCtrl.content.findName("MyButton");
      button.width = 50; // this do work because i can see the width is changed when i invoke the function
                
    }
    </script>
