I have implemented a FileExplorer on my site that works great for uploading files.  I would like to allow users to download files to local computers.  I have followed the demo located here:
http://demos.telerik.com/aspnet-ajax/fileexplorer/examples/applicationscenarios/filteranddownloadfiles/defaultvb.aspx?#qsf-demo-source


I think that I have most of the code without errors.  

Here is the question:
What do I put in the code behind on the Handler.ashx file??

I did not see a resource/related files on the demo for the Handler.ashx

Right now, I have two GridBoundColumns pulling OfficePhone and Extension from a SQL database.


I would like to combine the two columns into one, into something like this:


but extension is usually null or "", causing most of the cells to go blank.

Is there a way to set the expression programmatically, depending on whether there is a value for extension?

Telerik Embedded skins are not apply for radcontrols in IE. For that Some expert told to add a Radstylesheetmanager to combine stylesheet request into single one.

if i add radstylesheetmanager like this

 string telerikAssembly= typeof(RadGrid).Assembly.FullName;
                    RadStyleSheetManager stylesheet = new RadStyleSheetManager();
                    
                    StyleSheetReference css1 = new StyleSheetReference();
                    css1.Assembly = telerikAssembly;
                    css1.Name = "Telerik.Web.UI.Skins.Telerik.Grid.Telerik.css";
                    stylesheet.StyleSheets.Add(css1);

                    StyleSheetReference css2 = new StyleSheetReference();
                    css2.Assembly = telerikAssembly;
                    css2.Name = "Telerik.Web.UI.Skins.Office2007.Grid.Office2007.css";
                    stylesheet.StyleSheets.Add(css2);
                    
                    StyleSheetReference css3 = new StyleSheetReference();
                    css3.Assembly = telerikAssembly;
                    css3.Name = "Telerik.Web.UI.Skins.Black.Grid.Black.css";
                    stylesheet.StyleSheets.Add(css3);
                    this.Page.Header.Controls.Add(stylesheet);

Hello everybody,

I need to find a way to have a preview of the file like img files.
To explain better.
I had developed a new innovative CMS and one of the feature inside it, is the option to export and import CSS style and functionality of every object in the page.
For example if I have a menu very cool, and I want to export the graphic style and the functionality (template) into my library, I just follow this sequence:

1. Take a snapshot of the object (menu or any other things)
2. Go to the style Editor (it's a CSS realtime editor like the classic toolbar of Word. You can edit any object's CSS just using mouse)
3. Link the snapshot to the class CSS of the object
4. Go to the export manager
5. Select the object I want export (export in .zip file) and click ok

Hi ,

In the protected void RadGrid1_UpdateCommand  after editing values, when i extract values using 
e.Item.OwnerTableView.ExtractValuesFromItem(newValues, editedItem);

newValues hashtable is filled with oldValues not with edited values.I am using GridEditableItem only.



Please help me. 

Thanks
Swarna.

Hi everyone, I'm working with the radeditor control but when I click on spellcheck button 
I'm getting this error message "Sys.ArgumentException: Sys.ArgumentException: Cannot deserialize. The data does not correspond to valid JSON. Parameter name: data" . I tried this control on my local machine already and worked fine, but when I send it to the server it doesn't work.

Note: 

1) My server is working in integrated mode

I have a page that is similar to your Web Mail example.  Depending on selected view from TreeList it loads grid in main window.  What I would like to do depending on selected view is add or remove grouping from grid.  Can you please post an example or link to example to make this work?

Thank you
