RadEditor javascript error (this._contentHiddenTextarea.form) when using with RadGrid

[Anh Tuan]

Hi everyone,

I'm facing the js error, and i didn't identify the reason yet.

<telerik:RadTabStrip MultiPageID="uxMultiPage" ID="uxTabStrip" runat="server" CssClass="TabStrip">
    <Tabs>
        <telerik:RadTab meta:ResourceKey="uxTabA" PageViewID="uxTabA">
        </telerik:RadTab>
        <telerik:RadTab meta:ResourceKey="uxTabB" PageViewID="uxTabB">
        </telerik:RadTab>
        <telerik:RadTab meta:ResourceKey="uxTabC" PageViewID="uxTabC">
        </telerik:RadTab>
    </Tabs>
</telerik:RadTabStrip>

I put 2 RadEditors in uxTabA, some aspx controls to uxTabB, and i put the RadGrid (Classic RadGrid with using AJAX built-in feature inside) - named uxGridSource in uxTabC

I'm using the ImageButton - named uxCmdSave on the CommandItem in uxGridSource .
After clicking the button uxCmdSave, everything is OK, but i'm getting the client error

Line: 310715465
Error: 'this._contentHiddenTextarea.form' is null or not an object

after that, i cannot navigate to any tab (i'm using 3 tabs as described above) on my page.
I think that this error is thrown from RadEditor, but i do not know what the solution is yet.

However, if the page is PostBack fully by any button on the page (not on the RadGrid), this error does not occurs.

Please help me.

Hi Anh Tuan,

Please set RegisterWithScriptManager property to false , e.g.

<telerik:RadEditor runat="server" RegisterWithScriptManager="false" ...

I the problem still persists, please, isolate it in a sample working project and send it for examination on our end.

Best regards,
