hi,

Radmenu with repeatcolumns=2 and rtl enabled does not show the items correctly in ie 7. but works well in ie8 and mozilla.

<telerik:RadMenu ID="RadMenu1" runat="server" dir="rtl" Skin="Black">

            <Items>

Passing Variable from web method (aspx) to javascript

Hi,
I am trying to execute a code behind web method in javascript using PageMethods. The problem I am facing is as below:

    
            <WebMethod()> _ 
        
                    Public Shared Function Insert(ByVal charge As String, ByVal clientid As String) As String 
        
                    Dim value as string 
        
                    'Do The insert and retun value 
        
                    Return value 
        
            End Function

Below is the javascript code and the insert method gets executed based on a confirm window:

    
            function DoSomething1(sender, eventargs){  
        
                var txtRa = document.getElementById(sender.get_attributes().getAttribute("AssID"));  
        
                txtRa.value="";  
        
                var charge = sender.get_text();  
        
                if (trim(charge)!=""){  
        
            charge = charge.replace("'", "\'");  
        
                    var message = '<%= Resources.NoExist%>'  
        
                    if(confirm(message)) {  
        
                        var clientid = sender.get_attributes().getAttribute("ClientID");  
        
                        var ret = PageMethods.Insert(charge,index);  
        
                        alert(ret);  
        
                           DoSomething2(ret);  
        
                   }

The javascript code doesnt wait for the function to return a value and hence is executing the alert even before the insert function is complete. So, I end up getting an 'undefined' value for ret parameter.

Is there any way we can synchronously wait for the method to complete, get the return variable, set it in a hidden variable and use it in the rest of the javascript.
the webmethod does not have access to the UI controls on the page, as it is a shared web method.
I am open to moving this webmethod to a web service but I am not sure how the javascript would wait for the codebehind function to complete.
I have tried setTimeOut method in javascript to see if that will cause the wait but that dint work. The alert got fired with 'undefined'.
The webmethod does not take a long time to execute either. It only takes a few seconds. I just cant figure out how I can wait on the client side for the return parameter.

Please help me with any ideas and I am pretty much open to trying out anything at this point.

thanks in advance,
Kal.

RadGrid / GroupHeader with aggregates

Hi all,

I would like to create a grid with GroupHeaders containing sum-values of some columns (see attached image).
The group can be expanded so all 'sub-data' are aligned in columns under the corresponding GroupHeader columns.
This would be a nice compact overview of data.

As far as I can see, aggregates can only be placed in the Footer. It doesn't look nice, and one group always takes 2 rows which is a 'waste' of space.

If this cannot be done in a RadGrid - what else can I do ?

Thanks

problems retrieving selected item on combobox

Hi,

I'm having some problems using the radcombobox.

I'm loading the combobox with an ObjectDataSource and when I want to get the selectedItem, selectedValue or selectedIndex, they are always null, "" or -1.

I was reading that combobox cannot access data when you use on demand loading, but what's mean?

that it's the code:

                    <telerik:RadComboBox ID="rcb_leads" runat="server" Width="290px"         
                    DataValueField="IDLEAD" Filter="Contains" DataTextField="EMAIL"          
                    DataSourceID="ods_getLeads" Text="Search" AutoPostBack="True"          
                        onselectedindexchanged="rcb_leads_SelectedIndexChanged" >         
                    <HeaderTemplate>         
                        <table style="width: 275px" cellspacing="0" cellpadding="0">         
                            <tr>         
                                <td style="width: 177px;">         
                                    Lead Name</td>         
                                <td style="width: 60px;">         
                                    Email</td>         
                            </tr>         
                        </table>         
                    </HeaderTemplate>         
                    <ItemTemplate>         
                        <table style="width: 275px" cellspacing="0" cellpadding="0">         
                            <tr>         
                                <td style="width: 177px;">         
                                    <%# Eval("FIRSTNAME") + " " + Eval("LASTNAME") %></td>         
                                <td style="width: 60px;">         
                                    <%# Eval("EMAIL") %></td>         
                            </tr>         
                        </table>         
                    </ItemTemplate>         
                </telerik:RadComboBox>         

and the datasource:

                     <asp:ObjectDataSource ID="ods_getLeads" runat="server"          
                    SelectMethod="GetLeadByUserId" TypeName="LeadSius.stuff.DataAccess">         
                    <SelectParameters>         
                        <asp:SessionParameter Name="userId" SessionField="_userId" Type="Int32" />         
                    </SelectParameters>         
                </asp:ObjectDataSource>         

What is wrong with that?

Regards

CRUD on all hierachy tables

I am using RadGrid and have a design which greatly requires nested (hierarchy) tables. I was thinking about using LinqDataSources to bind each table level. However, in all the examples I have seen, the hierarchy tables are presented as read-only in the demos.

Is it possible to Create Retrieve Update Delete on hierarchical tables? If so, where would a demo of this live?

Thanks, M
