I have (tried) to configure our app as per http://docs.telerik.com/devtools/aspnet-ajax/controls/captcha/troubleshooting/using-webfarm-or-webgarden-environment, but am missing some important detail as I cannot get the Captcha default validation to work. The user inputs the Captcha.Text in a textbox (ValidatedTextBoxID="rcTextBox1"). I can trace a test scenario where the Page_load is executed on one application processor and the Post_back is executed on a second application processor. The Captcha.Text in the post_back is from a different(local, initialized) CaptchaImage (a new CaptchaImage.Text and noCaptchaImage.PreviousText).  I can pass the original Captcha.Text in Session (sql server) and over-ride the default verification using the user input so I have a work-around. But my expectation is the default Captcha should work "out-of-the-box". I somehow expected I should be able to pass the original CaptchaImage created in the Page_Load to be used in the Post_back. I can save the original image ( Session["CaptchaImage"] = Captcha.CaptchaImage) from the Page_Load but I can't get RadCaptcha to use it directly. I can't set the Captcha.CaptchaImage or Captcha.CaptchaImage.Text from Session as these are only Getters.

Questions:

1)  If I set mageStorageLocation="Session" why doesn't the control do the equivalent of a Session["CaptchaImage"] = Captcha.CaptchaImage / Captcha.CaptchaImage = Session["CaptchaImage"] for me.

2) If I must save the CaptchaImage in Session, what do I do with it on th ePost_back?

3) Why does ValidatedTextBoxID="rcTextBox1") cause the rcTextBox1.Text to be ""? I had to copy it to a HiddenField with JavaScript to retrieve the use input.

 

How can I force the post back of the RadSearchBox (onSearch event) when someone chooses one of the items from the ContextList? I want to be able to change a secondary list when an item from the ContextSearch is changed (just like they entered something in the search window and clicked search).  I tried to fire the postback of the SearchBox but it doesn't seem to be returning it to the server to process the items selected.  It seems to fire the panel update, but not the server side OnSearch event.

 

                        <telerik:RadSearchBox ID="RadSearchBox1" runat="server" RenderMode="Lightweight"
                                              DataTextField="DiagForList" MaxResultCount="15"

                        <DropDownSettings Width="500px" />
                        <Localization DefaultItemText="All Orders" LoadingItemsMessage="Loading...." />
                        </telerik:RadSearchBox>

 

 

Script:

 

    function pageLoad() {
        var $ = $telerik.$;
        $(".rsbSCSlide ").on("click", ".rsbListItem", function (e) {
            e.preventDefault();
            RaiseClickEvent('RadSearchBox1');
                });

    }
    function RaiseClickEvent(id) {
      __doPostBack(id,'arguments'');
    }

 

Why am I getting this error in Visual Studio 2012 all of a sudden? No problem yesterday, today I get this:

        pdfDoc.Open()

        hparse.Parse(srdr)

        pdfDoc.Close()

        Response.Write(pdfDoc)
        Response.[End]()
When I run it I get an error:
Script control 'RadAjaxManager1' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Can anyone please help with this as I have looked everywhere and anything I have tried doesn't work!!!.
Any help would be very welcome.

Hi,

I am using rad editor in me current project,the scenario is that I every user in database has a table of members having varying Fields in table. i e. these field are dynamic in nature and thus varies based on used.these dynamic fields need to be places in html inside the rad editor so that I can change the value of these fields programatically in HTML.

in my current implementation I validates the HTML on server to check if user has written these fields in HTML (format is like %%MemberName%% or may be something else enclosed in %%%%) then I replaces these values programatically with valid values.

But now according to our client's requirement he want a right click context menu, or drop down list or button on rad editor toolbar to display  and choose these dynamic fields so that the user dont need to remember which fields are dynamic and he can just select those fields to insert in email template in rad editor.

How can I achieve this.Please help me ?? or provide some better alternative?

Hi,

At the moment it doesn't appear possible to drag an Outlook email (.msg file) from Outlook on to the drag and drop box for uploading. It's possible to do it by dragging the email to the desktop to create the .msg file and then drag it to the RadAsyncUpload box but I want to just be able to drag an email directly from Outlook to the upload box.

When will it be possible to achieve the above or what is needed to implement it?

Thanks

Hi,

I have a problem to handle z-index on ImageManager and ImageEditor popup windows. In our application, we override z-index in .RadWindow_Bootstrap class ( .RadWindow_Bootstrap { z-index: 100000 !important; } ) to make sure ImageManager popup window display on top of other controls. The issue happens if we try to open ImageEditor window, the two windows shares the same css class, so the ImageEditor window is underneath of ImageManager window.

Is there any way we can solve it?

 

Thanks in advance,

Hello,

I am having problem to display video in RadMediaPlayer

Server Environment:
Windows Server 2008 R2
IIS 7.5
Video file format mp4

Client Environment:
Windows 10
IE Version 11.540.15063.0

Windows 7
IE Version 11.0.9600.18163


Problem:
There was not MIME type "video/mp4" in the IIS - I have added that one

After that the video displays in the Chrome, FF, and IE 11 on Windows 10, but does not in IE 11 on Windows 7
When I changed source from local file (/video/testvideo.mp4) to Telerik demo site example
http://demos.telerik.com/aspnet-ajax/media-player/examples/functionality/mediatypes/video/justCode.mp4
The video displays correct in the all browsers on Windows 10 and Windows 7.

Thank you
