Hi, it's my problem:

I have one radsplitter with one radgrid and one radeditor like this:

                    <telerik:RadSplitter ID="RadSplitter1" runat="server" Skin="Windows7" Orientation="Horizontal">
                        <telerik:RadPane ID="RadPane1" runat="server" Width="40%" MinHeight="32" Scrolling="Both" CssClass="buttonsPane">
                            <asp:Panel runat="server" ID="pnllistado">
                                radgrid
                            </asp:Panel>
                        </telerik:RadPane>
                        <telerik:RadSplitBar ID="RadSplitBar1" runat="server" CollapseMode="None"></telerik:RadSplitBar>
                        <telerik:RadPane ID="RadPane2" runat="server" Width="60%" MinHeight="32" Scrolling="Both" CssClass="buttonsPane">
                              radeditor (it starts hidden)
                        </telerik:RadPane>
                    </telerik:RadSplitter>


i don't understand why this error comes? : t.newSize is undefined
this error comes in the load of my page and this load in blank. help me please! thanks

Hi Juan,

Is the RadEditor's ToolBarMode property is set to RibbonBar (or RibbonBar variation). If this is the case, we are aware of such problem with the control that was already fixed. If you are not using the latest version of RadControls for ASP.NET AJAX (currently 2012.2.724) could you please upgrade your application to this version and see if the problem still occurs.

If this is not the case, could you please provide more detailed information on the specific scenario?

• Which version of RadControls for ASP.NET AJAX and .NET Framework are used in the application?
• Under which browser and its version the problem occurs?
• Could you please provide a simple fully runnable project reproducing the problem so we can investigate it further?

All the best,
Dobromir

Thanks you have the reason, the problem was for the version of dll's from Telerik.
