Are there any ready-made examples of how I could bind RadAutoComplete to a SharePoint list via web services? 

Hi All. How Can i get Tile Badge Value using javascript.???

i Have a radgrid (rad1)  inside a FormTemplate of another RadGrid (rad2).

If i update a row in (rad1) while (rad2) is in editmode, the (rad1) UpdateCommand get only empty values. ,


how i can do it????

UPDATE: i found that this happen because NeedDataSource of (rad1) is beign called before UpdateCommand,
this doesnt happens if the radgrid is not inside of another RadGrid.

Hello Team,

I have used telerik rad editor in my application.

In my application there are image library, audio library, video library.

I have bound this library with rad editor image manager, video manager, media manager.
(for e.g: used code for bind my library
 rtfEditor.ImageManager.ContentProviderTypeName = typeof(Telerik.ContentProvider.TelerikDBContentOfPhotoManager).AssemblyQualifiedName;
 rtfEditor.MediaManager.ContentProviderTypeName = typeof(Telerik.ContentProvider.TelerikDBContentOfMediaManager).AssemblyQualifiedName;
rtfEditor.FlashManager.ContentProviderTypeName = typeof(Telerik.ContentProvider.TelerikDBContentOfFlashManager).AssemblyQualifiedName;
)

Above all functionality working fine.

Now Problem is that in my database there are folder name or image gallery name or video gallery name is saved but when these folders is bind inside image manager / video manager / medai manager. it is not html decode to display folder or gallery name.

For Example my folder name is <April's obra> inside database I have saved with HTML Encode and its "&lt;April&#39;s Obra&gt;"
but I need to display "April's obra" in folder name.

for other controls like rad grid its automatically HTML decoded.

I have attached here screen shot for it.

Hi Telerik

I am using a couple lines of css to get the vertical scroll on the left side instead of the right. Putting the css in works as expected but the horizontal scroll now positioned on the right instead of the left most position.



The bold css for the rtl moved the vertical scroll but also adjust the hor scroll to the right. Is there a way i can move that hor scroll back to the left? Any css needed?

Thanks!

hi my dear friends:

How Can I Show Just Date In A BoundColumn (Date Format In SQL Server 2008 Not DateTime) In Rad ComboBox?

we do not have any DataFormatString For A Bound Column here Like In RadGrid....

Hi,

I'm simply looking to return the text from a listview where I have an id for the key field and a name field which is what is displayed.  I thought this would be relatively simple but keep failing. 

Also I can't seem to find a way to get the first item selected by default when the page loads.

I thought for sue I could find something like this in the forums but came up empty.

Thanks

Hi There,

I was trying to find CheckBox in the form using below code. When user clicks on the "SAVE" button, if user does not check checkbox in the form, it should ask user to select the "CheckBox" using Message box(Yes\No). If user selects "Yes" then it should automatically check the CheckBox. Please help.
