Hi Yannis,

There is a new content filter in the latest version of RadEditor named ConvertCharactersToEntities which converts the special characters to entities. You can disable it by setting

RadEditor1.DisableFilter(Telerik.Web.UI.EditorFilters.ConvertCharactersToEntities);

in the codebehind. You can test how the content filters work in this live demo: Built-in Content Filters.

Hi Yannis,

RadEditor does not offer this feature, but if more users request it we will implement it.

Currently, you can create your own custom filter that will contains only the desired symbols that you want to convert to their entities:

<telerik:radeditor OnClientLoad="OnClientLoad" runat="server" ID="RadEditor1"></telerik:radeditor>

<script type="text/javascript">

function OnClientLoad(editor, args)

{

editor.get_filtersManager().add(new MyFilter());

}

MyFilter = function()

{

MyFilter.initializeBase(this);

this.set_isDom(false);

this.set_enabled(true);

this.set_name("ConvertCharactersToEntities");

this.set_description("This filter converts reserved characters to their html entity names.");

this.entities = {

Hello Aristotelis Pitaridis,

Here is an example on how to get a reference to RadEditor placed in ItemDataBound of RadGrid:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if ((e.Item is GridEditableItem) && (e.Item.IsInEditMode))
    {
         GridEditableItem edititem = e.Item as GridEditableItem;
         RadEditor radEditor = e.Item.FindControl("RadEditor1") as RadEditor;
         radEditor.OnClientLoad = "OnClientLoad";
    }
}

After that attach the OnClientLoad function to the OnClientLoad property of RadEditor and make sure that the JavaScript OnClientLoad function is available on the page when the editor is displayed on the page.

Best regards,
Rumen

Thank you Rumen for your reply but I think that I found a better way to handle it. My code is the following:

Protected Sub grdArticles_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs)

If (TypeOf e.Item Is GridEditableItem AndAlso e.Item.IsInEditMode) Then

Dim item As Telerik.Web.UI.GridEditFormItem = e.Item

Dim MyRadEditor As RadEditor = item("Article").FindControl("ArticleRadEditor")

MyRadEditor.DisableFilter(Telerik.Web.UI.EditorFilters.ConvertCharactersToEntities)

End If

End Sub

Article is the field in which I have placed the RadEditor control and ArticleRadEditor is the name of the control. In my project it works fine. Please correct me if I have made some kind of mistake in my code.

Hello Baldwin,

You can see how to executing custom code called on RadEditor's events in DNN in the following KB article: Executing custom code called on RadEditor's events. This solution works only for RadEditor DNN provider provided by Telerik.

If you use the Professional DNN provider of RadEditor, you should note that it is implementation of the DNN developers and it is not supported by Telerik. Our suggestion is to post the question about how to register the external skin files of RadEditor in DNN in the DNN forums. For example in this one: Taming (customizing) The new Telerik RadEditor.

Hi Wangji,

Did you try to disable the ConvertCharactersToEntities filter of RadEditor which converts the Greek symbols to entities? Open the configuration file and remove the ConvertCharactersToEntities string from the ContentFilters enum values:

<configuration>
<property name="Skin">Default</property>
<property name="NewLineBr">false</property>
<property name="ContentFilters">EncodeScripts,FixUlBoldItalic,ConvertToXhtml,IECleanAnchors,MozEmStrong,IndentHTMLContent</property>
...
