"Same" combo box repeated a lot of times

Hi,

Here is my situation: on a page used to match items from list A with items from list B, I repeat the "same" RadComboBox presenting the items from list B (via a load on demand webservice) for each item of list A.

    
            <asp:Repeater ID="rptr" runat="server" OnItemDataBound="rptr_ItemDataBound"> 
        
               <HeaderTemplate> 
        
                  <table cellpadding="0" cellspacing="0" class="hspace"> 
        
                     <tr> 
        
                        <th><asp:Literal ID="lblItemA" runat="server" Text="Item A" /></th> 
        
                        <th><asp:Literal ID="lblItemB" runat="server" Text="Item B" /></th> 
        
                     </tr> 
        
               </HeaderTemplate> 
        
               <ItemTemplate> 
        
                  <tr> 
        
                     <td><asp:Literal ID="ltrlItemA" runat="server" /><asp:HiddenField ID="hfIdItemA" runat="server" /></td> 
        
                     <td> 
        
                        <telerik:RadComboBox ID="rcmb" runat="server" Skin="Default" Width="300px" ShowMoreResultsBox="true" EnableVirtualScrolling="false"  
        
                           EnableLoadOnDemand="true" MarkFirstMatch="true" ItemRequestTimeout="500" OpenDropDownOnLoad="false" ShowDropDownOnTextboxClick="false"> 
        
                           <WebServiceSettings Path="services/RadControlsHelper.asmx" Method="SearchItemB" /> 
        
                        </telerik:RadComboBox> 
        
                     </td> 
        
                  </tr> 
        
               </ItemTemplate> 
        
               <FooterTemplate></table></FooterTemplate> 
        
            </asp:Repeater>

The scenario is that for each item of list A we assign an item from list B.

With numerous items in the lists (let's say 1000), the page is horribly slow on IE8. Horribly slow in the sense that it never actually loads, IE8 crashes. Firefox seems to handle it much better.

Can you provide any insight on how I could fix my problem ? My thoughts were :
1) Use a paging control to display less items at once (but no less than 100).
This is merely a workaround, not a real fix though...

2) Some Telerik functionality to share the same combo client-object since it's always the same items being loaded. (similar to SharedCalendarID in RadDatePicker)

3) Create one single invisible RadComboBox outside the Repeater and manually manipulate it though javascript to reuse it and save the result in an hidden field for each item.
Effectivelly doing a manual 2)

What are your thoughts? Thanks.

Dominic.

DatePicker showPopup()

Hi,
using the DatePicker, I wanted to show the calendar clicking on its Dateinput. This is the cs code I used:

    
            ForwardCalendar.DateInput.Attributes.Add("onclick", string.Format("$find('{0}').showPopup();", ForwardCalendar.ClientID)); 
        
            ForwardCalendar.DateInput.Attributes.Add("onfocus", string.Format("$find('{0}').showPopup();", ForwardCalendar.ClientID)); 
        
            ForwardCalendar.DateInput.Attributes.Add("onblur", string.Format("$find('{0}').hidePopup();", ForwardCalendar.ClientID));

In this way the calendar shows correctly, both when I click on the dateinput and when focusing it. The problem is that selecting a date on the calendar does nothing. No date is written on the dateinput.
When I click on the popup button, instead, it works perfectly.
Any idea?
Thanks.

[Solved] Modules Hidden With Only 1 Edit Mode

What does anyone know about the following behaviour?

A RadEditor has been set up to only show its 'Design' edit mode, (as we don't want our users seeing HTML - they're not that technically savvy), but also had its "statistics" module enabled within the "bottom" docking zone; we have a requirement for including this information.
The module isn't displayed because it seems to hide the entire row that includes this docking zone when only one mode is set. I can verify this by adding a second "edit mode" and both the buttons and module are displayed as desired.

It's fairly important that we find a way around this limitation, (or is it a design feature?), because of our project's requirements.

Thanks,
Paul

Tabbing in HTML Mode

Hi, in the Classic radEditor, when you go to HTML mode, you can tab lines over to indent. But in this version of radEditor, that doesn't seem to be possible. Tabbing just sets the focus on the next element within the editor. Is there something I have to do to make that work? In the Classic version, it worked by default. Thanks.

[Solved] Need to move Minimize Command to the Left Side

Hello,

I need to have "Minimize" command to be displayed on the left side of the Dock. Other commands should be displayed as they are right now - on the right side. What would be the best approach to solve this?

Thank you,

Image Properties - preserve aspect ratio

In the Editor, the image propreties dialog has a preserve aspect ratio gadget - looks like a couple of plugs that plug together when you click on it.

It's unplugged by default - so aspect ratio is not preserved.

Is there a way to change this so that it is plugged in, by default? So that aspect ratio is preserved, when editing images, unless the user specifically asks that it not be?
