Error textarea tinyMCE ASP.NET C# Tengo un problema extraño, no se me ocurre porqué puede pasar.
En mi aplicacion ASP.NET con C# tengo una pagina.aspx donde está un formulario donde hay cajas de texto, labels, botones y un textarea ( <textarea name="descripcion" cols="50" rows="10" id="IDdescrip"></textarea> ).
En realidad esta pagina.aspx no tenia ningún textarea , pero en realidad mi objetivo es reemplazar un textbox por un textarea , de modo que pueda usar el tinyMCE . Así que seguí el procedimiento, pegué las carpetas respectivas en la ruta donde se encuentra mi pagina.aspx, he hice las referencias respectivas dentro de la pagina.aspx:
<!-- TinyMCE -->
<script type="text/javascript" src="jscripts/tiny_mce/tiny_mce.js"></script>
<script type="text/javascript">
tinyMCE.init({
// General options

// Replace values for the template plugin

}
});
</script>
<!-- /TinyMCE -->
He logrado que el textarea tenga las caracteristicas que le de el tinyMCE, pero lo extraño es que cuando escribo algo (ssssssssssddddddd) dentro de ese textarea y doy click en el boton grabar, sale el siguiente error:
Server Error in '/WebPostes' Application.
A potentially dangerous Request.Form value was detected from the client (descripcion="<p>ssssssssssddddddd...").
Description: Request Validation has detected a potentially dangerous client input value, and processing of the request has been aborted. This value may indicate an attempt to compromise the security of your application, such as a cross-site scripting attack. You can disable request validation by setting validateRequest=false in the Page directive or in the configuration section. However, it is strongly recommended that your application explicitly check all inputs in this case.
Exception Details: System.Web.HttpRequestValidationException: A potentially dangerous Request.Form value was detected from the client (descripcion="<p>ssssssssssddddddd...").
