I am getting the following client-side error message.  It appears that Telerik's JavaScript is failing.  Can anyone give me a kick in the right direction as to how to figure out what might be going wrong?

Here is the Telerik javascript that appears to be failing:

 

 

Sys.UI.Control=function(a){Sys.UI.Control.initializeBase(this);this._element=a;
<line 6, char 94383>
a.control=this};

It all looks good, but is there any documentation on client-side API, I wonder?
I failed to find one, except for http://www.telerik.com/help/aspnet-ajax/ribbonbar-client-programming-basics.html which is pretty limited.

For example, I would like to hide/display tab on client-side.
I've tried bar._tabs.getTab(1).get_pageView().style.display = "none"; but it does not hide the "tab strip" part.

I may eventually find the solution, but I wonder if there is a documentation somewhere that I'm missing... Please advise.

I am new to RadTabStrip, ann came across something that need your help. 

I am using RadTabStrip with RadMultiPage. I open new aspx files for each of the Tabs.
Now I need to add a button to the first Tab, which will load the second tab and display it's content. (Just like, any other link which will open the requested link).

But when  I give the implement the onclick event of the button to navigate to the second aspx file (Booking.aspx), it will simply load another Tabstrip inside the first Tab. It results in showing the radtadsrip again inside the first tab. 

Please help me to open the second tab using the button, in the same way as if it is navigated by clicking on the second tab.

Below is my aspx file: 
  <telerik:RadTabStrip ID="RadTabStrip1" runat="server" Skin="Web20" MultiPageID="RadMultiPage1"
            SelectedIndex="0" Align="Justify" ReorderTabsOnSelect="true" Width="800px">
            <Tabs>
                <telerik:RadTab Text="DashBoard">
                </telerik:RadTab>
                <telerik:RadTab Text="Booking">
                </telerik:RadTab>              
            </Tabs>
        </telerik:RadTabStrip>       
        <telerik:RadMultiPage ID="RadMultiPage1" runat="server" SelectedIndex="0" CssClass="pageView"
            Width="800px" Height="520px">
            <telerik:RadPageView ID="RadPageView1" runat="server" Width="100%" Height="100%">
                <iframe frameborder="0" width='800' height='520' scrolling="yes" src="Dashboard.aspx">
                </iframe>
            </telerik:RadPageView>
            <telerik:RadPageView ID="RadPageView5" runat="server" Width="100%" Height="100%">
                <iframe frameborder="0" width='800' height="100%" scrolling="yes" src="Booking.aspx">
                </iframe>
            </telerik:RadPageView>         
        </telerik:RadMultiPage>

Hi,

Thanks,

Hi

I have long series names in a legend so I have set AutoTextWrap = true, but they wrap too much!
1 of the series names is wrapping over 3 lines instead of 2 lines, so I thought I'd make the legend box wider to accomodate it, but it ignores everything I've tried. I've attached a pic.
These lines do nothing:

• RadChart1.Legend.Appearance.Dimensions.Width = new Telerik.Charting.Styles.Unit(50);
• RadChart1.Legend.Appearance.ItemTextAppearance.Dimensions.Width = new Telerik.Charting.Styles.Unit(150);

while this line makes the legend disappear:

• RadChart1.Legend.Appearance.Dimensions.AutoSize = false;

Here is the markup:
and here is the relevant code behind:

What am I doing wrong?

Is there any in-built support to save filters and load them back instead of specifying filters everytime?
