Detect editor ID in managers

[Fit2Page]

Hi,

I use a customized Linkmanager.ascx

How can I detect in the Linkmanager.ascx which editor openened the Linkmanager when there are multiple RadEditors on the page?

Hi Marc,

Steps to achieve the requested feature:
1) Default.aspx:

<telerik:RadEditor ID="RadEditor1" runat="server" OnClientLoad="OnClientLoad" ExternalDialogsPath="~/EditorDialogs"></telerik:RadEditor>
<script type="text/javascript">
    var editorObject = null;
    function OnClientLoad(editor) {
        editorObject = editor;
    }

    function invokeTopPageMethod(fileName) {
        alert("The RadEditor's ID is " + editorObject.get_id());
    }
</script>

2) LinkManager.ascx:
Put at the end of the file the following function:

<script type="text/javascript">
    function pageLoad() {
        window.top.invokeTopPageMethod();
    }
</script>

window.top is used to access a method from the parent page from the iframe based dialog of RadEditor.

Hi Rumen,

Your code is not working where there are multiple editors on the page.

I achieved the desired functionality with

clientInit: function(clientParameters)
{
this._clientParameters = clientParameters;

var editor = this._clientParameters.editor;
alert(editor.get_id())

I copied this from FindAndReplace,ascx.
This gives me the correct sender for every Editor instance on the page.


EDIT: This is even mentioned in the LinkManager file itself:
//Editor object is supplied to all dialogs in the dialog parameters
var editor = this._clientParameters.editor;
Sorry I didn't discover this earlier.

Hi Rumen,

I am still working on this issue.

What I am initially trying is to detect a language value from the editor in the LinkManager.ascx

I saw that there is a common way to send an extra parameter to the dialog, I think this is a good way of achieving the desired functionality:
http://www.telerik.com/community/forums/aspnet-ajax/editor/add-query-string-to-telerik-web-ui-dialoghandler-aspx.aspx

When I try so I get the following error message:

Invalid length for a Base-64 char array.

[FormatException: Invalid length for a Base-64 char array.]
   System.Convert.FromBase64String(String s) +0
   Telerik.Web.UI.Common.XorCrypter.Decrypt(String encoded, String key) +30
   Telerik.Web.UI.DialogHandlerNoSession.get_DialogParametersProviderTypeName() +61
   Telerik.Web.UI.DialogHandlerNoSession.get_DialogParametersProviderType() +13
   Telerik.Web.UI.DialogHandlerNoSession.CreateChildControls() +159
   System.Web.UI.Adapters.ControlAdapter.CreateChildControls() +15

   Telerik.Web.UI.DialogHandlerNoSession.OnPreLoad(EventArgs e) +18
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +554

Any ideas what could cause this?

Hi Fit2Page,

Do you use some other encoding for your page than UTF-8? If this is the case I suggest to change it to UTF-8 and run the Spell Check to see if this helps. Here is a forum thread discussing the encoding issues with the Spell Check:

http://www.telerik.com/community/forums/aspnet-ajax/editor/spell-check-handler-server-error-500-invalid-length-for-a-base-64-char-array.aspx

This problem is fixed in the Q3 2010 Beta build of RadControls for ASP.NET AJAX and will not exist in the official Q3 2010 build, which is scheduled for 10^th of November:

What’s Fixed

• Fixed: System.FormatException: Invalid length for a Base-64 char array sometimes raised for non-unicode websites under .NET 2.0

Note that I try to get the additional parameter to the LinkManager dialog.

I am using UTF-8 that is not the problem.

I am trying to send from code behind:

Dim byt As Byte() = System.Text.Encoding.UTF8.GetBytes("NL")
editor_Text.DialogOpener.AdditionalQueryString = Convert.ToBase64String(byt)


That fails with the Base 64 error

When I send from client side it works with:

editor.get_dialogOpener().set_additionalQueryString("&Taal=NL");

Do you have a clue why the server site approach won't work?

Hello Marc,

Our recommendation is to not encode the URL string with Convert.ToBase64String method because it could contains the + and = symbols, which are reserved symbols for the URL querystring and the RadEditor's dialog URL already contains them.

All the best,
