Issue with custom filter

[Yuriy Yurkovskiy]

I've tried to implement my custom filter, as described in the following article:

http://www.telerik.com/help/aspnet-ajax/contentfilters.html

As a result, I got the following error:

"Telerik.Web.UI.Editor.Filter is null or not an object."

Could someone help please?

P.S. I've already added RadScriptManager and RadAjaxManager on my page.

Hi Yuriy,

This error most often occurs if a custom content filter is registered before the declaration of the RadEditor control, thus the instance of the Telerik.Web.UI.Editor is not initialized. You can also get this error if the editor is placed in non editable mode or is initially hidden.

You can put the code inside the following block

if (typeof ($telerik) != "undefined") {
...
}

and see whether the problem still persists.

If this is not the case, could you please send us a fully working project reproducing this error so we can investigate the issue further?

All the best,
Rumen
