The program runs perfectly on my machine but when I try to execute it on an other machine, it crashes after the splash screen. I have checked the event viewer and I have copied the following stack report. I am sure that if can access the details of the inner exception to see what causes the crash I am also sure that I would be able to solve my problem. I have already lost 1 week because of this issue. Please give me an idea for solution and sorry for my poor English.

I'd guess a control or library is missing on that machine or you are trying to access some resource that is missing.

Try copying all the binaries + matching .pdbs over to the other machine. You can install WinDbg which is a very small debugger from Microsoft (just a few MBs) vs. Visual Studio and debug through there.

Binding a SolidColorBrush resource of Theme

Prasoon Chaudhary22-Dec-11 23:22

22-Dec-11 23:22

I need a binding in SolidColorBrush color value inside my theme. So basically, instead of

HTML

<SolidColorBrush x:Key="TextBrush" Color=" #FF000000" />

I want something like -

HTML

<SolidColorBrush x:Key="TextBrush" Color="{Binding ColorVal}" />

Property could be defined something like this:

namespace ns
{
    public class BindingClass
    {
        public Color ColorVal
        {
            get
            {
                return Color.FromRgb(255, 0, 0);
            }
        }
    }
}

Hopefully it's possible. What should I write instead of 'Binding expression' in XAML theme?

Update:

I've got one solution-
On top,

HTML

xmlns:local="clr-namespace:ns"

Then a Resource key,

HTML

<local:BindingClass x:Key="BindingClassKey"/>

Finally binding,

HTML

<SolidColorBrush x:Key="TextBrush" Color="{Binding Source={StaticResource BindingClassKey}, Path=ColorVal}" />

Any better solution?

Just have menu levels in your xml file.

<Navigation>
  <item>Converter</item>
  <tag>/UserControls/Converter.xaml</tag>
<FirstLevel>
 <item> sub level</item>
<tag>sub level</tag>
</FirstLevel>
</Navigation>
<Navigation>
  <item>Page1 view</item>
  <tag>/Views/Page1.xaml</tag>
</Navigation>
<Navigation>
  <item>Test Page</item>
  <tag>/Views/Test.xaml</tag>
</Navigation>

Yes, but how do I make it appear on the UI?
At present, I just read the item and tag of the xml file.
Does this mean that if I also read the FirstLevel element, then it will automatically show up in the UI and a sub level menu?
Thanks

It will not automatically show up.

[silverlight]How to customerize the readonly for each datagridcell

Loveisasea21-Dec-11 21:43

21-Dec-11 21:43

I have a entitycollection and assigned a readonly property for each property of the entity. So that I can define whether they can be modified in Datagrid.

For example,for the same property NAME, it is allowed be be edited for some entities but others not.

But seems there is not a DataGridCell.IsReadOnly in silverlight as in WPF.

Anyone of you have met similar case ? or know that the silverlight 5 will get this supported?

Hi All,

I have a silver light application where I am trying to access a csv file by using the following way

List<string> listoflines = (List<string>)File.ReadLines(@"C:\Users\amohammad\Desktop\Bugs\30958\tasksandtaskstatuses2.csv");

But its giving my Access Denied message. Is there any way to read a file in silverlight. But I dont want to use the use FileStream or StreamReader. Because I want to read all the lines at a time and assign in the above way.

Is there any way to access the read the files in silverlight irrespective of its access rights. Because here we are just reading the file. I know that if we keep it in my documents then I can read the files. But Can I read the files irrespective of its location and access rights.

Thanks & Regards,

If you think about what you are asking for a minute, you can see that the ability to read any file at any location using a method like this, regardless of access rights, would represent a huge security vulnerability.

As Pete was not very clearly hinting, you aren't allowed to access the local file system in silverlight because thats a security breach. Imagine if any web site could install a silverlight app on your machine and access your c:\documents\bank records.doc and make a copy. Not good!

If you are using SL4, there is a work-around as you can access the local file systems *IF* your app is running with elevated permissions and is trusted. Even then, you only have access to a few folders. Again, a security consideration.

In SL3 and below, you can not access the local file system at all.

using silverlight,actually it does not allow the client side application to fetch the data from outside the project.The data can be fetched in only two ways ,first if it is stored locally using isolated storage or its a resource file.

Curently i have downloaded expression blend trial to see what i do. I have made simple triangle.

HTML

<Path Data="M395.25,283.625 L403.75,295 C403.75,295 388.37515,294.875 388.37515,294.875 C388.37515,294.875 395.25,283.625 395.25,283.625 z" HorizontalAlignment="Left" Height="12.375" Margin="189.891,0,0,188.625" Stretch="Fill" UseLayoutRounding="False" VerticalAlignment="Bottom" Width="16.375" Fill="#FF00B6BA"/>

So my question is, is there a tool that can convert StreamPathGeomtry (Path.Data) into a normal XAML graphic no matter how complex is? I want to see how complex graphics works.

I appreciate any help.

PS: Do not convert this for me.
