Hello,

i have this javascript code

    
               function AccesDirectFicheCadre() { 
        
                            var cb = $find("<%= AccesDirect_List.ClientID %>"); 
        
                            var item = cb.get_selectedItem(); 
        
                            var id = item.get_attributes().getAttribute('Id'); 
        
                       // Some other actions using "id", but "id" is ALWAYS undefined... :( 
        
                        }

With this :

    
               <telerik:RadComboBox  
        
                                runat="server" ID="AccesDirect_List"    OnClientItemsRequested="OnClientItemsRequested" 
        
             ShowDropDownOnTextboxClick="false" 
        
                             MarkFirstMatch="true"  
        
                             EnableVirtualScrolling="true" NoWrap="true" MaxHeight="210px" 
        
                                EnableLoadOnDemand="true"  
        
                                HighlightTemplatedItems="true" EnableViewState="false" 
        
                                OnItemDataBound="RadComboBox1_ItemDataBound"  
        
                                OnItemsRequested="RadComboBox1_ItemsRequested"> 
        
                            </telerik:RadComboBox>

and this

    
                   protected void RadComboBox1_ItemDataBound(object sender, RadComboBoxItemEventArgs e) 
        
                    { 
        
                        //set the Text and Value property of every item 
        
                        //here you can set any other properties like Enabled, ToolTip, Visible, etc. 
        
                        e.Item.Text = ((DataRowView)e.Item.DataItem)["Nom"].ToString(); 
        
                        e.Item.Value = ((DataRowView)e.Item.DataItem)["Id_Cadre"].ToString(); 
        
                        e.Item.Attributes["Id"] = ((DataRowView)e.Item.DataItem)["Id_Cadre"].ToString(); 
        
                    }

The problem is that in my javascript function, the "id" is ALWAYS undefined, i'm unable to access the "Attribute" value i have set in the codebehind method.

How can i do this ?

Thank you

Hello,

Can you change the attribute name other than 'Id' and see whether it is working? I tried different name and got it working.

cs:

    
                protected void RadComboBox1_ItemDataBound(object sender, Telerik.Web.UI.RadComboBoxItemEventArgs e) 
        
                { 
        
                    e.Item.Text = ((DataRowView)e.Item.DataItem)["CategoryName"].ToString(); 
        
                    e.Item.Attributes["myId"] = ((DataRowView)e.Item.DataItem)["CategoryID"].ToString();  
        
                }

javascript:

    
            <script type="text/javascript"> 
        
                function AccesDirectFicheCadre() { 
        
                    var cb = $find("<%= AccesDirect.ClientID %>"); 
        
                    var item = cb.get_selectedItem(); 
        
                    var id1 = item.get_attributes().getAttribute('myId'); 
        
                    alert(id1); 
        
                } 
        
            </script>
