How to register second event handler for client's ButtonClicked?

Hi,
I would like to register a second event handler for the RadToolBar's client side event "OnClientButtonClicked". Is that somehow possible?
The first event was registered by adding it to the toolbar's "OnClientButtonClicked" property.

Best regards
Ferdinand

<script type="text/javascript">

var context = e.get_context();

//using jQuery to get the checked item and pass it to the server

context["ProductSuite"] = $telerik.$("input[name='rblSuites']:checked").val();

}

function OnClientItemPopulatedHandler(sender, e) {

var items = e.get_item().get_items();

for (var i = 0; i < items.get_count(); i++) {

var item = items.getItem(i);

//getting the attribute of the item

var myCustomAttribute = item.get_attributes().getAttribute("MyCustomAttribute");

//do something with the attribute

RadCompression and Viewstate Validation

Hello, I have the RadSessionPageStateCompression enabled on my site, however I keep getting these errors since upgrading to 2010 Q1:
Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster. However, I don't use a Web Farm and my machine key and validation key are properly defined in the web.config. What could be the probable cause?? I am using Session State to store some info of the user and FormsAuthentication (i don't now if that has something to do but with my problem)... The IIS version I am using is 6.0 and .net Framework 3.5 SP1. I also have radcompression postbackcompression enabled and my viewstate encryption mode is set to "Auto".

Thank you in advance,
Manuel

PS: I also generate my radgrids dynamically on page init.

[Solved] Grid Context Filter Menu fires Page Validators

Hello,
I have a RadGrid with the EnableHeaderContextFilterMenu="true". The problem is when I try to use the filter it validates all the controls on the page. So an end user would have to fill out a form before they can filter a grid that's on the same page as the form. I was hoping there is a way to change the validation group for the filter menu or set its causesvalidation to false because we would prefer to keep our main form's controls at validation group defaults.
Thanks.

Axis Labels display issue

Hi,

I have a telerik radchart created dynamicaly in my web page. I have made the series orientation of the graph to Horizontal so that i get more space to display the x-axis labels in the graph. My axis label texts are quite lengthy & i am not able to display them to the full. After few charecters, they are getting displayed with "..." as shown in attached image-1. I want to display the complete text for labels. The complete text is shown in Image-2.

Also i dont want any negetive numbers in y-axis. Meaning i want the start value to be Zero. I tried setting minimum value=0 but was of no help :(.

Please help me fixing these issues ASAP.

Thanks,
Krishna Samaga B.

Table overlaps RadPageView in content panel on detail page

I am building a radgrid dynamically and adding columns selected by the user at runtime. The radmultipage is on the content panel of a master page inside a div:

    
                    <div style="position:relative; margin-top:10px; margin-left:55px; margin-right:60px">  
        
                                      <asp:contentplaceholder id="ContentPlaceHolder1" runat="server">  
        
                                       </asp:contentplaceholder> 
        
                     </div>

on the child page the grid is inside a pageview of the multipage:

    
                    <telerik:RadPageView ID="PageView4" runat="server" Width="100%" > 
        
                    <table width="100%" cellpadding="5">  
        
                        ...  
        
                        <tr> 
        
                        <td>      
        
                        <telerik:RadGrid   
        
                            ID="radgridResources"   
        
                            runat="server"   
        
                            AllowPaging="True"   
        
            ...

In IE6 the pageview would expand to accomodate the size of the radgrid and keep the appropriate borders. In IE7 Q1 2009 the grdi overlaps the pageview. You can see the prolem here:

Any help greatly appreciated.
