Hi

I have a javascript function that extracts a custom attribute from a treeview node and uses this to decide whether to hide or show the expand button. This works spot on when expanding a node.

However, I also store the treeview XML in a session variable so that when user navigates back to this page the treeview will be in the same shape as they left it. I have attached a function to the treeview OnClientLoad that uses recursion to naviage through all the expanded nodes toggling the expand button as required. Again this works fine.

However - and might not be possible - when a user navigats back to the page all the nodes have an expand button until the js function runs - which is very quick - a second maybe - however this looks unprofessional as the nodes disappear down the treeview.

Is there way to get around?

As a suggestion for future releases, if I may, it would be extremely handy to be able to set this client side

Filtering in Grid with AutoPostbackOnFilter Issue

I have a lot of Grids with default filtering: AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false"

Using 2009.3.1109.35 RadGrid filtering crash when if any column that AllowFiltering="true" and not set DataField and try filter for any column.

Example:

                    ...         
            <Columns>         
            <telerik:GridBoundColumn DataField="ID_ENTIDAD" HeaderText="Id." ReadOnly="True" SortExpression="ID_ENTIDAD" FilterControlWidth="50px"         
                 AutoPostBackOnFilter="true" CurrentFilterFunction="EqualTo" ShowFilterIcon="false" >        
            </telerik:GridBoundColumn>         
            <telerik:GridTemplateColumn DataField="DSC_ENTIDAD" HeaderText="Entidad" SortExpression="DSC_ENTIDAD" FilterControlWidth="99%"          
                 AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false">         
                 .....        
            </telerik:GridTemplateColumn>         
            <telerik:GridTemplateColumn [DataField="BOL_ACTIVO"] DataType="System.Boolean" HeaderText="Activo" SortExpression="BOL_ACTIVO"         
                AutoPostBackOnFilter="true" CurrentFilterFunction="EqualTo" ShowFilterIcon="false"> 
            .....        
                    
                    
            </telerik:GridTemplateColumn>         
            </column>         

if you forget [DataField="BOL_ACTIVO"] any filter don't run. Lauch Postback, but OnInit of grid don´t execute.

If you mark this column AllowFiltering="false", all OK.

RadComboBox - slow under IE6?

Hello,

We have just added the RadComboBox to a page in our site for Country selection, to replace the existing lookup based on the Ajax Control Toolkit Auto Complete Extender (as clients has commented that this was too slow).

The ComboBox is loaded during Page_Load with a list Countries from the database (237 rows), in the same way that you would load a normal ASP.NET DropDownList. The definition for the ComboBox in the page markup us as follows:

    
            <telerik:RadComboBox ID="cboIssueCountry" runat="server" Height="200px" width="190px" Skin="WindowsXP"   
        
                 EnableEmbeddedSkins="false" EmptyMessage="" MarkFirstMatch="true" AllowCustomText="false"></telerik:RadComboBox>

It works absolutely fine running under IE7 and IE8, the response is pretty much instant. However it is painfully slow under IE6. It takes 1 or 2 seconds after entering any characters for the list to be displayed and the matching item selected. This is a problem for us as most of our clients (unfortunately) are running IE6!

Is this a known problem? Any advice on how we can improve the perfomance?

Thanks in advance.

Basic Problem

Hi,

I'm new to this control and seem to be having some trouble getting it to work correctly. I've got an XML file as the data source, however the control only ever shows the first item in the list.

My code is as follows:

    
                    <telerik:RadRotator ID="RadRotator1" runat="server" DataSourceID="xmlData" RotatorType="AutomaticAdvance" ScrollDuration="2000" ScrollDirection="Up" FrameDuration="1" Height="200" ItemHeight="100" Width="200" ItemWidth="100">  
        
                        <ItemTemplate> 
        
                            <%#System.Web.HttpUtility.HtmlEncode(XPath("Message").ToString())%> 
        
                        </ItemTemplate> 
        
                    </telerik:RadRotator> 
        
                    <asp:XmlDataSource ID="xmlData" DataFile="Messages.xml" XPath="Messages" runat="server"></asp:XmlDataSource>

XML Source:

    
            <?xml version="1.0" encoding="utf-8" ?> 
        
            <Messages> 
        
              <Message>Frasers Message</Message> 
        
              <Message>Marks message</Message> 
        
              <Message>Jimmys message</Message> 
        
            </Messages>

It's probably something obvious - can anyone help me out please?
