Hi,

I want to enable creation of new folders in the RadFileExplorer. For this I set the property accordingly on control creation:

    
                    private RadFileExplorer CreateAndInitializeExplorer() 
        
                    { 
        
                        RadFileExplorer explorer = new RadFileExplorer() 
        
                        { 
        
                            EnableViewState = true, 
        
                            VisibleControls = FileExplorerControls.All ^ FileExplorerControls.AddressBox, // only disable AddressBox. show everything else 
        
                            Width = 900.Pixel(), 
        
                            EnableCreateNewFolder = true, 
        
                            EnableCopy = false 
        
                        }; 
        
                        explorer.Load += Explorer_OnLoad; 
        
                        explorer.PreRender += Explorer_PreRender; 
        
                        explorer.Configuration.ContentProviderTypeName = typeof(MyContentProvider).AssemblyQualifiedName; 
        
                        string[] basePath = MyContentProvider.GetRootsPaths(); 
        
                        explorer.Configuration.ViewPaths = basePath; 
        
                        explorer.Configuration.UploadPaths = basePath; 
        
                        explorer.Configuration.DeletePaths = basePath; 
        
                        return explorer; 
        
                    }

Still, the toolbar and context menu items to create a new Folder are not displayed. All DirectoryItems (that is really every single Item) that are provided from MyContentProvider have the following permissions set:

    
            private const PathPermissions FULL_PERMISSIONS = PathPermissions.Read | PathPermissions.Delete | PathPermissions.Upload;

So there should be no problem with the permissions of the item.

Please help me to get this sorted out. I need the Create New Folder functionality available for my users.

Regards,

Sebastian

Docking Error : Scriptmanager 'System.Web.Configuration.ScriptingScriptResourceHandlerSection' to type 'System.Web.Configuration.ScriptingScriptResourceHandlerSection'.

Hello
I am trying to add dock control to my web page.My web page has a vald asp.net 3.5 scriptmanager. but it has started to give this error :
The control with ID 'RadDockZone1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.

I am pretty sure there is a scriptmanager on the page.I tired to set RegisterWithScriptManager="false" property and try again.But after that ,it throwed that error

Unable to cast object of type 'System.Web.Configuration.ScriptingScriptResourceHandlerSection' to type 'System.Web.Configuration.ScriptingScriptResourceHandlerSection'.

I searched internet ,it was suggested to change webconfig ajax part like this to solve this problem :

   <runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
       <dependentAssembly>
        <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0" />
      </dependentAssembly>

      <dependentAssembly>
        <assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35" />
        <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0" />
      </dependentAssembly>
    </assemblyBinding>
</runtime>

I did it ,but it did not work still same error given ,any idea ?

Thanks in advance

[Solved] Is there any way to Drag/Drop into a RadEditor?

I've been trying to get either the client-side or server-side functionalities of the drag/drop option of the listbox to drop into a RadEditor, but nothing seems to be working... any advice would be appreciated. Thanks.

P.S. I'm not even 100% sure this is possible... but I'm 100% hoping it is.

Problem for Export to Excel

Hi,

I have a LinkButton outside of RadGrid for triggering Export to Excel.

public

void LinkButtonExportToExcel_click(object sender, EventArgs e)

{

int rowCount = RadGridProduct.Items.Count;

if (rowCount <= 0) { return; }

RadGridProduct.ExportSettings.ExportOnlyData =

true;

RadGridProduct.ExportSettings.IgnorePaging =

false;

RadGridProduct.ExportSettings.OpenInNewWindow =

true;

RadGridProduct.MasterTableView.ExportToExcel();

}

It worked fine before but not now. After I clicked the LinkButton, no Excel opened in the new window and my RadGid had lost all of Filter controls and other controls inside ItemTemplates. Am I missing something?

Thanks,

Enoch

Loading Selected dock layout from database

I have successfully implemented from your sample a portal page using the dock that saves and reloads from the database dependant on user. However the user has different roles and therefore different portal pages. This is selected by a dropdown on the page.

The problem I am having is as the dynamically loaded dock state is actioned on the initialization of the page the new selected value of the dropdown is not available until the load stage.

Can you please advise how I can load the dock from the database dependant on the selected value of the dropdown.

Thanks

Mark

ItemTemple lost its value which was set in

Hi Team,

I am not able to retain value of combobox when i click on "Click Me" in my code. Please help me. My code as below.

Code Behind Code:-

[Solved] Run Startup JS Code after Telerik JS Objects Exist

    
            // Find the RadControl client object, if null then exit the function  
        
            sb.Append(String.Format("var co = $find(\"{0}\");", c.ClientID));  
        
            sb.Append("if (co == null) return;");

When I register this code with the Page.ClientScript.RegisterStartupScript method it attempts to execute before the Telerik Control Javascript objects are created resulting in "co" being assigned a null value. How do I register startup Javascript code that executes AFTER the Telerik javascript objects are created.
