Hi Amit,

RadEditor's file browsing dialogs are using RadFileExplorer, which is using RadGrid. RadGrid is using two formats of FilterExpressions: SQL for .NET 2.0 and if EnableLinqExpressions is false and LINQ for .NET 3.5 and EnableLinqExpressions is set to true (default). Generally the grid LINQ expressions are almost exactly the same to the normal code (C#/VB.NET).

Are you using a custom filebrowser content provider and / or custom resource provider? If so, could you try disable them and see if the problem still occurs? If so, could you please provide more detailed information on the specific scenario?
  • Which version of RadControls for ASP.NET AJAX and .NET Framework are used in the application?
  • Could you please provide a simple fully runnable project reproducing the problem so we can investigate it further?

In addition, could you please try to set the EnableLinqExpressions of the RadGrid component to false to see if the problem still exists? In order to achieve this you need to modify the built-in FileBrowser.ascx dialog. In the attached project you can find a sample page with this modification applied.

I have the same problem.
Clicking any icon related to Managers dialogs (ImageManager, FlashManager, DocumnetManager, TemplateManager) cause this error.

I tried to apply your solution modyfing built-in FileBrowser.ascx.
It helps for all dialogs except the ImageManager.
In the ImageManager dialog I got the following error:

Object reference not set to an instance of an object.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

Source Error:

Line 8:          {
Line 10: 	            rfe.Grid.EnableLinqExpressions = false;
Line 11:         }  
Line 12:     }  

Source File: [.....]\EditorDialogs\WebUserControl1.ascx    Line: 10

Please advice.

Hi Igor,

RadEditor's ImageManager dialog have set Thumbnails view set as default view for the FileBrowser and Grid component is not available. To avoid this problem you should check if rfe.Grid property is not null before assigning a value to any of its properties, e.g.:
if(rfe.Grid != null)
    rfe.Grid.EnableLinqExpressions = false;

I have found a reason of this error. The problem was in using of our custom Resource Provider.
In our web.config  it is defined as

 <globalization uiCulture="auto" culture="auto" resourceProviderFactoryType="OurResourceProviderFactory, ..." />

I tried to specify ExternalDialogsPath and LocalizationPath in RadEditor but it didn't help for ImageManager.
I solved the problem by changing our ResourceProviderFactory class:

  public override IResourceProvider CreateGlobalResourceProvider(string classKey)
        {
            if (classKey.Substring(0, 3) == "Rad") // RadGrid.Main, RadEditor.Dialog e.t.c
                return null;
            else
                return new OurResourceProvider(classKey);
        }
