Using Scripts via Server-side Content property
How-to
Enable Script tags in the content, set via the Server-side Content property of the RadEditor control
Solution
You should disable the RemoveScripts and the EncodeScripts built-in content filters on the Page_Load event and then set the desired Script in the content.
<telerik:RadEditor runat="server" ID="RadEditor1">
</telerik:RadEditor>
protected void Page_Load(object sender, EventArgs e)
{
RadEditor1.DisableFilter(EditorFilters.RemoveScripts);
RadEditor1.DisableFilter(EditorFilters.EncodeScripts);
string initialContent = @"
<script type=""text/javascript"">
alert(1);
</script>";
RadEditor1.Content = initialContent;
}
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
RadEditor1.DisableFilter(EditorFilters.RemoveScripts)
RadEditor1.DisableFilter(EditorFilters.EncodeScripts)
Dim initialContent As String =
"<script type=""text/javascript"">" +
"alert(1);" +
"</script>"
RadEditor1.Content = initialContent
End Sub
