Edit Mode OnLoad

[Damon]

Hi,

Is there any way to get radeditor to load in preview mode with design mode still enabled in the server side code?

Cheers

Hello Damon,

You can load RadEditor in Preview mode using the following JavaScript code:

<telerik:RadEditor runat="server" ID="RadEditor1" OnClientLoad="OnClientLoad">
    <Content>Sample Content</Content>
</telerik:RadEditor>
<script type="text/javascript">
    function OnClientLoad(editor, args) {
        setTimeout(function()
        {
            editor.set_mode(4);
        }, 100);
    }
</script>

You can set RadEditor in Preview mode only on the client side. In order to achieve your scenario you should import this script using one of the server-side methods: Page.RegisterStartupScript or Page.RegisterClientScriptBlock.

More information is available in this blog post: Executing JavaScript function from server-side code.

Hi Rumen,

Thanks for the info, it helped greatly. I ended up using the below example to solve my issue of the radeditor returning to preview mode on postback.

Javascript:

function treNotesLoad(editor,args) {
    var Postback = document.getElementById("<%=csPostback.ClientID%>");

    if (Postback.value == "N") {
        editor.set_mode(4);
    }
}

HTML:

<input type="hidden" id="csPostback" name="csPostback" runat="server" />

VB.NET

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    If Not IsPostBack() Then

        ' Set the client side postback indicator hidden to NO
        ' Used to allow javascript to tell if the page is postback
        csPostback.Value = "N"

    Else

        ' Set the client side postback indicator hidden to YES
        ' Used to allow javascript to tell if the page is postback
        csPostback.Value = "Y"

    End If

End Sub

Thanks again for the information!
