I have created a EPIServer CMS site using visual studio. I am able to access the site using edit mode. I want to add some image on that site. But when I am trying to upload a image using the upload option it is showing failed message.Why it is happening do you have any idea. But when I have uploaded the images from the demp 'Aloy Site' given by EPIServer team it is uploaded successfully.
Please tell the probable cause of this.
Thanks and regards

I also got the fail to upload images. Firstly I thought it was a config-setting or a permission problem. But it turned out that I needed a "media descriptor".
You can read about it here. This applies for EPiServer CMS 7.x
C# example:
[ContentType]
[MediaDescriptor(ExtensionString = "jpg,jpeg,jpe,gif,bmp,png")]
public class ImageFile : ImageData
{
public virtual string AlternativeText { get; set; }
}

We are having one problem while generating a link preview for our react application URL's. Actually we have the requirement to display the dynamic link preview for different URLs.
We are able to add the link preview by using open graph tags in our index.html file placed under the public folder.
But once we tried to add dynamic metadata using the "react-meta" or "helmet" package. it is successfully changing the title of the application. but links preview are not working after making these changes.
so I kindly let me know if there is any way that we can different link preview for different urls for react application. Thanks in advance.
I currently new in ReactJS, And I work this project using laravel and this reactjs. I have question regarding why when i open my web application intead the application is shown why the list of folder shown to my browser?
Scenario: It happen when i upload the whole project to the server it shows look like this.
Do i need to configure in my files so that when i browse my application it will automatically redirect to the application.
You must visit the public directory of your project or if you use virtual host, set the public directory as the entrance.
When I set uri string value into richimage src property, I can not see the image on application ui.
If I try to paste the value into browser it shows the image
ie: file:/C:/Users/Dijitaluser/AppData/Roaming/JDeveloper/system11.1.1.6.38.61.92/o.j2ee/drs/IncomingPaperWorkWebApp.war/WEB-INF/classes/com/acme/resource/images/upload_file.png
As a matter of fact, if i put the image file into the same project as you say image/thefile.png, that's ok. But I use distributed resources project and I get the uri by using resourceBundle. So this solution is useless for me.
I' m trying to test application on my integrated weblogic server, and this uri which is returned by resourceBundleHelper, is already validated by browser. Could you plz give me some suggestions about the issue.
I trasnformed my resources project to web project to use web.xml about defining resources servlet. Then moved my all images in META-INF/adf/images and added into my VisualResourceBundle(extends ListResourceBundle) class.
It works

I want to use localization feature for Validation messages, for eg-
[Required(ErrorMessageResourceName = "RequiredField", ErrorMessageResourceType = typeof( ))]
public string someText
{ get... set...}
I'm using MVVM pattern so this property is in my model(its a differnt project inside same solution of silverlight) and all my localization resources are in the App.current.Resources. How can I set the ErrorMessageResourceType to my App resources?
Please suggest.
Thanks in advance

Well apparently Localization of error messages isnt as straightforward. You are supposed to add a resource file to the MyApp.Web project, that is the asp.net site that hosts your silverlight app, then add that resource to the silverlight app, then you will be able todo the code you stated in your question after some tweaks, follow the instructions below
This section explores how error
messages can be localized by storing
them in resource files and sharing
them across tiers.
The example uses .NET RIA Services
walkthrough project as the base
project and builds on top of it.
Let's say we want to add a validation
error as a resource for LoginID field.
Create a new ‘Resources' folder in the HRApp.Web project
(server project)
Add a new resource file to this folder and name it
ValidationErrorResources.resx
Double click on the .RESX file to bring up resource designer
page
Add a new string resource with Name= LoginIDValidationError and
Value= "LoginID field is required"
Change the access modifier to ‘Public' by clicking on the ‘Access
Modifier' drop down UI and selecting
‘Public' and save the project. This
generates a ValidationErrorResources
class in the HRApp.Web.Resources
namespace.
Open ‘OrganizationService.metadata.cs' file
and add the following ‘Required' field
validation to LoginID member. Specify
the error message resource name and
resource type values by setting the
corresponding attribute members as
shown below.
[Required(ErrorMessageResourceName =
"LoginIDValidationError",
ErrorMessageResourceType =
typeof(ValidationErrorResources))]
public string LoginID;
Now we want to share this resource
file in the Silverlight project
(client project). To do this,
Create a folder Web\Resources in the HRApp project
(folder structure must match the
resource file namespace on the server
side)
Select Resources folder and bring up Add Existing file dialog,
browse to the server side resource
file folder location
Select ValidationErrorResources.resx and
ValidationErrorResources.designer.cs
files, and add them as link files to
the Silverlight project. Save the
project file
Open HRApp.csproj file in notepad , locate the section where
.designer.cs file is included and add
the highlighted 3 lines to this
section
<Compile
Include="..\HRApp.Web\Resources\ValidationErrorResources.Designer.cs">
<AutoGen>True</AutoGen>
<DesignTime>True</DesignTime>
<DependentUpon>ValidationErrorResources.resx</DependentUpon>
<Link>Web\Resources\ValidationErrorResources.Designer.cs</Link>
</Compile>
Save the project file and reload the project in Visual Studio
Build the solution and run
Now whenever the validation fails for
the LoginID field the error message
from the resource file is shown to the
user. The resource file can now be
customized to store locale specific
error messages.
This solution almost worked for me. I had to made some arrangements to work with a data model (edmx) located in one project, DataDomainService (Ria) in other and the Silverlight access layer in other project.
When i compile the HRApp equivalent in my situation, the metadata containing the validation info for some property is not generated. It says that the client has no access to the ValidationErrorResources type. But after following all the instructions mentioned above plus some others to get a correct resource namespace, the client CAN access ValidationErrorResources.
It works if i write it myself to the generated Silverlight class.
So seems like this kind of project separation is not quite supported by the class generator...
But thanks anyway, this post was quite helpful and maybe i'll make it all work in a couple of days.
:D
When I did this recently this thred helped alot: http://forums.asp.net/t/1433699.aspx
In particular "...the resource file must be converter to a class before being able to reference it in the typeof of the ErrorMessageResourceType in the data annotation..."
Also there are a few other useful hits from the main search engines: http://www.liquidjelly.co.uk/supersearch/?q=silverlight%20dataannotations%20localization&lang=en-GB
I'm making a WebPart for SharePoint that will instantiate a Silverlight UserControl and feed it some data. My problem is that when I have created my sample-WebPart and just instantiate a Silverlight control, the webpart, when added to a page or displayed in the webpart gallery, instead of rendering blank, renders an error page saying "File Not Found". No clue in the logfiles to what file was not found or why this error is thrown. Here is my code:
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.SilverlightControls;
namespace TestSLWP {
public class CustomWebPart1 : WebPart {
protected override void CreateChildControls() {
Label lblHello = new Label();
lblHello.Text = "Hello";
Controls.Add(lblHello);
Silverlight sl = new Silverlight();
}
}
}
I've added references to System.Web.Extensions and System.Web.Silverlight to the project. They are in the GAC, and the webpart is written and compiled on the same computer that SharePoint resides. If I change the CreateChildControls() to be:
protected override void CreateChildControls() {
Silverlight sl = new Silverlight();
sl.ID = "CustomWebPart1SL";
sl.Source = "/Silverlight/CustomWebPart.xap";
this.Controls.Add(sl);
}
I get the same error. Also if I remove the first slash in sl.Source I get the same error, even though the file is present in a virtual directory in the same application pool as SharePoint. I therefore, and because the error comes with just instantiating the Silverlight object, believe that the file that cannot be found is not my XAP.
What file can't SharePoint find and what can I do about it?
Here's the error message:

Hi I found a complete walk through on how to get Silverlight web parts get running on your application: http://www.vbforums.com/archive/index.php/t-557072.html
As you can see there are added some more things to the web.config beside your assembly registration.
Enabling SilverLight requires a lagre amount of web config modifications. Did you add those?
There could be the problem with your storage folder with silverlight control. You must register path to this storage as safe in web.config (for example find in web.config line with "~/controltemplates").
