Hi guys,

There is a radcombobox and an asp checkbox in my page. On unchecking the asp checkbox, i want to remove all items from the radcombobox drop down. I tried using a javascript code and loop through all the items and access each one to delete, but it was not successful. I need a working javascript code.

Thanks,
Needha

Hi,

I'm using Js code to clone a dockzone and append it to a div:


Then I want to save the layout using StorageProvider.

However the client-side created dockzones and the docks inside the dockzones are not saved.

I assume the client-side created dockzone cannot be handled by the code-behind's GetRegisteredDocksState ?

What is the correct method to save the client-side cloned dockzone to the database or to get the serializedState ?

Thanks.

I am currently using Telerik RadControls for ASP.net Ajax Version 2012.3.1308.45,
When I set a MaxLength for RadTextBox to 255, everything works correctly except when Copy and Paste text or using mouse right click to paste text into the RadTextBox, it allow the line break '\n\r'  to bypass the MaxLength count.
Somehow from runtime value, I check and compare the length is more than the MaxLength.
This senarios happens in all sorts of browser (FF, IE, Chrome) and even in the Demo site,
I don't understand if this is the correct behaviour or bugs based on the calculation logic.

I would need to include the count for line break '\n\r' as well else it will hit SQL length limit to cause insert or edit error.
What else can I do to cater this?

I just uninstalled all my old telerik controls and installed the latest version of winforms 2013.1.321.0.

I working on a project that I haven't touched in a couple of years.  When I opened out the c# project I get many errors.

RadListBoxItem was giving me an error so I changed it to RadListDataItem and the error went away.  I haven't been able to view my forms because I have so many errors. 

This is the error i'm stuck on now and if anyone can help it would be greatly appreciated. 
This is my code previously


and I get this error:

Error    2    The type or namespace name 'RadListBoxItemCollection' could not be found (are you missing a using directive or an assembly reference?)   

I changed the code to

and this is the error i'm getting.

Error    2    'Telerik.WinControls.UI.RadListDataItemCollection' does not contain a constructor that takes '0' arguments   

Thank you

I have a rad grid that when exported to excel it gives the following error:

"The file you are trying to open [filename].xls, is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now?"

What can I do to resolve this error?

  <telerik:RadAsyncUpload runat="server" ID="ImgImages2" AllowedFileExtensions=".jpg,.jpeg,.png,.gif"
                            MaxFileInputsCount="1" Skin="Outlook" Width="350px" PostbackTriggers="PerformInsertButton" />

  byte[] fileData;
        if (ImgImages.UploadedFiles.Count > 0)
        {
            UploadedFile file = ImgImages.UploadedFiles[0];
            fileData = new byte[file.InputStream.Length];
            string ImgFileName1 = ImgImages.UploadedFiles[0].FileName;
            file.InputStream.Read(fileData, 0, (int)file.InputStream.Length);
            if (fileData.Length > 1048576)
            {
                RadWindowManager1.RadAlert("The length of the uploaded file must be less than 1 MB", 300, 100, "Check SetUp Signature", null);

Does anyone have any sample code to create a candlestick chart through code.  I've got the date in a datatable and i'm trying to configure the chart.

            s.DataLabelsColumn = "Date";
            s.DataYColumn = "Open";

            s.DataYColumn3 = "Low";
            s.DataYColumn4 = "Close";
