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

Filtering in database instead using telerik default filtering techniques

Hi

I would like to know that is it possible to rebind the datagrid in the item command event.
Since my requirement is to get the filter value such as date from the filter template and apply the filter in the database(instead in the grid itself) should get rebind ed after applying the filter values.

FYI
need_datasouce event is not firing after calling the grid.Rebind() method in the item command event.

Thanks

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

ImagesPath and HeaderImageUrl

From trying it out, I'd guess that the RadGrid's ImagesPath is not used for the GridBoundColumn's HeaderImageUrl. Don't you think that's a good idea?

Currently, if I am using ASP.NET themes and have my images and .skin files in a folder like ~/App_Themes/Default/, I have to point directly to that folder in the source for each GridBoundColumn where I am using a HeaderImageUrl or I have to write some code to set the image in the code behind. I shouldn't have to point directly to that folder anywhere except in the theme folder, really.

Another option would be to allow a SkinID on grid columns so I can set the images in the .skin file, kinda like how the RadMenu RadMenuItems work. :-)

Not a huge deal, but would help clean up my code a bit. :-)

[Solved] FIX: Server error after postback when you have an invisible RadSlider control on the page

Hi guys,

We have discovered a bug in RadSlider in Q1 2010 release (version 2010.1.309).

PROBLEM
A server error "Specified cast is not valid." can occur after postback, when you have an invisible RadSlider control (either the slider, or one of its parents, has "display:none" applied) with items, defined on the page.

SOLUTION
As a workaround, you can execute the following code, when the RadSlider control fires its load event:

    
            <script type="text/javascript"> 
        
                function OnClientLoad(sender,args) 
        
                { 
        
                    sender.updateClientState(); 
        
                } 
        
            </script>

    
            <telerik:RadSlider ID="RadSlider1" runat="server" ItemType="Item" OnClientLoad="OnClientLoad"

What is Next
The problem is already fixed and the fix will be available in the next Latest Internal Build and the first service pack.

Please accept our sincere apologies for the caused inconvenience.
