Insert error in RadScheduler - null value

Hi.

I have followed the AdvancedForm tutorial (http://www.telerik.com/help/aspnet-ajax/schedule_advancedformtemplate.html), and I have managed to include a user control to invite colleagues to an event. However when I try to save the event I get the following error:

Value cannot be null.

Parameter name: value

This is my Telerik RadScheduler:

                        <asp:Parameter Name="UserID" Type="Int32" />         
                        <asp:Parameter Name="RecurrenceRule" Type="String" />         
                        <asp:Parameter Name="RecurrenceParentID" Type="Int32" />         
                        <asp:Parameter Name="Description" Type="String" />             
                </InsertParameters>         
            </asp:SqlDataSource>         

One last note:

The error occurs even when I try to add an event from the inline-insert. So I believe this has more to do with the setup of the sqldatasource or perhaps the radscheduler.

Looking forward to your help :)

RadEditor: Value Cannot be null error when using custom Content Provider

We bought Q2 2012 SP1 (version 2012.2.724) to upgrade the old version. The primary purpose of the Telerik is to use the Radeditor as the WYSIWYG editor and manage file uploads. We'd been using old version for many years in the past and thought of upgrading due to new features and better browser support.

The default installation works ok in both dev and prodcution environment but wanted to use customprovider for all file uploads. The moment I switch to custom provider the Radedior File upload dialogs stars giving "Value Cannnot be null" erro intermittenetly. This happens only in production environement and the error pops up 50% of the time. When trying to expand the folder tree it hangs with the "rotating wheel animation" sometimes due to the same error.

Please help

Dev Environment: Windows 7 / IIS7 / Asp.NET 3.5
Production Environment: Windows Server 2008 / IIS 7 / Asp.Net 3.5

My sample code block is below.

protected void Page_Load(object sender, System.EventArgs e)

{

string[] sImagePath = new string[] {"/_Global/" + ModuleProperties.SiteID + "/img/content"};

radEdtContent.ImageManager.ViewPaths = sImagePath;

radEdtContent.ImageManager.UploadPaths = sImagePath;

radEdtContent.ImageManager.ContentProviderTypeName = typeof(myprovider).AssemblyQualifiedName;

}

public class myprovider : Telerik.Web.UI.Widgets.FileSystemContentProvider

{

public myprovider(HttpContext context, string[] searchPatterns, string[] viewPaths, string[] uploadPaths, string[] deletePaths, string selectedUrl, string selectedItemTag)

: base(context, searchPatterns, viewPaths, uploadPaths, deletePaths, selectedUrl, selectedItemTag)

{

}

public override string StoreFile(UploadedFile file, string path, string name, params string[] arguments)

{

//StoreFile method handles renaming of files if exists.

string fileExtention = name.Substring(name.LastIndexOf("."));

string fileNameWithoutExtension = name.Substring(0, name.IndexOf("."));

string newFileName = fileNameWithoutExtension + DateTime.UtcNow.Ticks + fileExtention;

string result = base.StoreFile(file, path, newFileName, arguments);

return result;

}

The Error

Server Error in '/' Application.

RadSpell not catching simple spelling errors

I'm using the latest reease (RadControls for ASP.NET AJAX Q2 2012 SP1) and it is not catching simple spelling errors (like goodby, thimg, etc.) Is there something wrong with the en-US.tdf dictionary??
I have attached a screen print.

by using this I can able to get the patients names but they are loading in dropdown,
<telerik:ResourceType DataSourceID="PatientDataSource" ForeignKeyField="PatientID"
                KeyField="UID" Name="PatientName" TextField="FullName" />

There are 4000 patients. The DropDown does not allow text based searches. Users must scroll through thousands of patients to find the one they are looking for.

Is there a control, such as autocompletefield, which better fits my needs?

RowClickEvent ClientSide Cancel or Activate

I am trying to either cancel the client side row click, or activate it, I don't care which, I just want something to work!

Mira, from the telerik support team, told me last week to use:

>>From your posts I assume that you have the EnablePostBackOnRowClick property set to true. To prevent postback if the confirm window returns false, please use the set_cancel() accessor method of the event arguments.

That errors and I read this post from 2009 where it says the grid no longer supports set_cancel()

http://www.telerik.com/community/forums/aspnet-ajax/grid/set-cancel-in-onrowclick-event.aspx

When trying to cancel the click, I had EnablePostBackOnRowClick="true"

And when trying to activate the click, I had: EnablePostBackOnRowClick="False"

I am using this for my grid click event:

    
            grdGrid.ClientSettings.ClientEvents.OnRowClick = "GetDirtyGridRowClickReviewer"

So I tried several other things from other posts and none work:

    
            <script language="JavaScript" type="text/javascript">  
        
            <!--

            {  
        
                var sContinue;  
        
                if (isDirty == 1) {  
        
                    sContinue = window.confirm("You have unsaved changes. Please select CANCEL if you would like to return to the form to save your changes. Please select OK if you wish to proceed and lose your changes.");  
        
                    if (sContinue != true) {  
        
                        //4/13/2010  
        
                        //http://www.telerik.com/community/forums/aspnet-ajax/grid/deselecting-event-set-cancel-true-does-not-preserve-selectcolumn-status.aspx  
        
                        // below does nothing, continues to selected row...

Can someone please provide a working example of canceling or activating row click client side after asking if you wish to proceed?

Thanks!

Rstoring Fields When Deleted From Transfer ListBox

I have 3 listboxes that transfer fields to a single listbox called "list_columns". Everything is working how I want it to, however, when I delete a column from "list_columns" the field does NOT get restored to the listBox that it came from. How do I make sure that once a column gets removed, it will be able to be selected again from the original ListBox?

Sales Dashboard using Q2 2012 Telerik DLLs

Hi,

I've downloaded the ASP.NET AJAX source code of Sales Dashboard http://demos.telerik.com/aspnet-ajax/salesdashboard/ and tried to integrate it with a purchased license of Q2 2012 version of Telerik. Somehow, the demo doesn't work using the newer version. I attached a screenshot of the error that occurs. Any thoughts on this?

Thank you

Content missing after RadAjaxLoadingPanel

I have two standard USB panels when I press the button I need to process fields on panel one, then hide panel one and display panel two. However when I press the button, the loading panel displays and the code behind fires... but once it is complete and the loading panel is hidden again the next panel is not shown. I have stripped the code down in another temporary file to remove all style sheets, external scripts etc etc and the problem still remains...

I simply can't see where I'm being stupid, please help :)

Having some trouble updating my grid. Ive added the controls in programatically as they differ per row, the text box, rad text box and numeric text boxes update no problem, but the date picker sends through an empty string and checkbox is always false. I will also be adding dropdown box which will no doubt have the same problems.

edit: checkbox always has original value, so if its true it will always get set to true on update no matter the state of the checkbox, same is happening for textbox and any other control

Any idea whats causing this or what im missing?

Thanks

Radwindowmanager confirmation server side

Dear friends,
I am using radwindowmanager in asp.net
can some one please give me a good idea how to using radwindowmanager confirmations message at server side!
Some thing like

Have two buttons on the dialog which are “Scan Another” and “Translate”. Scan Another will

clear the scanned bet image and reset the stake to £0.00. Translate will go immediate to the

translate tab with that bet selected.

This is what right now I am using!

<telerik:radwindowmanager id="RadWindowManagerTakeBet" runat="server" skin="Metro">

</telerik:radwindowmanager>

RadWindowManagerTakeBet.RadAlert("Stake Saved!", 330, 100, "No Bet Stake", null, null);

Thanks,
Shakti
