FilteringTemplateColumns not available as Column

Hi guys,

i followed the instructions from "Implementing filtering for template/custom columns".
I created a VB file named MyCustomFilteringColumn.vb, then add the tag
<%@ Register TagPrefix="custom" Namespace="<MyApplicationNamespace>" Assembly="<MyApplicationAssembly>" %>
in my aspx page.
Unfortunately, the intellisense doesn't show me the new column named "custom" like <custom:MyCustomFilteringColumn
After one week tries, i gave up.
Can someone please tell me why?
When i create a new ASP.NET Application Project, it does work. But it doesn't work in my current application.
NB: we are replacing old Grids with RadGrids in a big project, that's why i can't just create a new one and copy again the whole stuff.
I hope there is better solution or another alternative to deal with the custom column.

Here some properties of my application: LINK
And the declaration in the aspx: LINK

Thank you

Select/highlight one row at a time.

When selecting/highlighting all text then bold / change font etc. the entire text is quite rightly wraped with start and end tags.
What i want to do is wrap each line with the text change.
Reason being i am treating each carriage return or new line as an entry. If user selects the lot i need each line tagged not the lot.
Can i stop users from selecting the whole text can select one line only.

Grid and Edit Form with 2 different datasources

I have almost exactly the same problem as this thread but I do NOT have the key piece of knowledge to connect an entity data source.
http://www.telerik.com/community/forums/aspnet-ajax/grid/grid-and-edit-form-with-2-different-datasources.aspx
After reading above:

I am missing the boat on this one. I have my data access via Entity Framework and bind an entity data object to the datagrid no problem. I want my second datasource to bind to the NestedView BUT the only option I have is DataSourceID which is expecting a string value that represents, for example, a SQLDataSource object.....but I don't need one I already have my data so how do I get the entity data bound to the nested view...yes I could circumvent the entity and make it work but that would defeat using the entity???

What am I missing?

performance tuning - page load

I am trying to fine tune telerik .net application and need some expert help.

I used dot trace and yourkit profiler tools to come up with below page load stats. dot trace profiler gives method name, percent of time, actual time and number of calls per GUI event. At this point I am not sure how to read yourkit stats.

I have a transaction screen with 2 drop downs, two buttons and a blank(always) grid that is not attached to any database. Each button displays Ajax grid on click events.

All my grids are populated via database views and handle DML via stored procedures. Hence at any given point they are not attached/bounded to database table. I am not sure if they are bounded via db view or not. I hope not.

Also attached screen shot of web page.

Question
1) DO you see any unwanted methods called in page load event?
2) How to improve page load performance? Any basic things to look at?

IF REQUIRED I CAN GIVE LIVE APPLICATION ACCESS TO INTERESTED CANDIDATES.

Embedded Resource Pros/Cons

We are having an internal debate as to whether or now we should deploy the Prometheus controls with UseEmbeddedScripts and UseEmbeddedSkins enabled. It would be much faster to deploy with it turned on, because otherwise we would have to go through and change the setting on each of the controls and then move the skins and scripts out to the server. Opponents to the using embbeded resources are claiming the following as concerns:

1. Compressibility of the CSS/JS files,

2. When/how/if things are cached client side. (IF is the operative word?)

3. How a load balancer/load balancing situation would help/hurt

Can you provide any information as to how performance is affected by using embedded resources versus using static resources for the Prometheus controls?

Thanks,
Adam

Help with Sort Inside RadListView and RadAjaxPanel Sort Buttons Disappear

Hi,

I am trying to figure out how to apply a custom sort using the RadListView which is inside a RadAjaxPanel. Whenever I click on a LinkButton to cause a sort change, all the link buttons disappear.

Here is some code that shows the ascx layout:

    
                <telerik:RadAjaxLoadingPanel   
        
                    ID="RadAjaxLoadingPanelDiscussion"  
        
                    Transparency="1" 
        
                    Width="100%" 
        
                    Height="100%" 
        
                    runat="server" /> 
        
                <telerik:RadAjaxPanel

                    LoadingPanelID="RadAjaxLoadingPanelDiscussion" 
        
                    runat="server"  
        
                    > 
        
                    <telerik:RadListView

                                            </asp:LinkButton> 
        
                                            <asp:Literal ID="Literal1"

                                        <td> 
        
                                            <asp:LinkButton  
        
                                                ID="LinkButtonBody"  
        
                                                CommandName="Sort" 
        
                                                CommandArgument="Body" 
        
                                                Visible='<%# this.SortBody %>' 
        
                                                Font-Bold='<%# this.SelectedSort == DiscussionListWebPart.DefaultSortOption.Body %>' 
        
                                                runat="server"  
        
                                                > 
        
                                                Body  
        
                                                <asp:Image 
        
                                                    ID="ImageBody" 
        
                                                    Visible='<%# this.SelectedSort == DiscussionListWebPart.DefaultSortOption.Body %>' 
        
                                                    ImageUrl='<%# this.GetSortDirectionImageUrl() %>' 
        
                                                    runat="server" 
        
                                                    /> 
        
                                            </asp:LinkButton> 
        
            ...

The LinkButton.Visible property does not change, is always true, so that isn't the issue. It has something to do with the ajax call. Also, there is a Literal that has a visibility set to the same property. The Literals don't disappear, but all the LinkButtons that apply sort do.

Is there something else I need to wire up?

Thanks!
