[Solved] RadMenu within a TempateColumn

We have a grid and for each row, we need a RadMenu that will contain multiple action that can be performed on the row item. Our current implementation of the menu within the grid, the z-order is messing with us. The menu items are hidden under the grid.
Thanks

RadChart needs interface other than the Wizard

AMIRIGHT?

I mean shouldnt I be able to change axis, legend, plotarea, etc properties interactively on the chart control itself? why cant i selct the legend on a chart and see the properties in the IDEs Properties window like other .net controls? why do I have to use the wizard? It rewrites my markup anyway when I use it, i try to avoid it.

Is this on the plate for the Devs?

Please Please redo the chart interface

Selfhierarchy/Paging Issues when AllowPaging="True" and RecordSet Exceeds PageSize Value

I have a radgrid that displays selfhierarchical records. When I have the following set:

    
            AllowPaging="False" 
        
            AllowCustomPaging="False" 
        
            EnableLinqExpressions="True" 
        
            -OR- 
        
            AllowPaging="False" 
        
            AllowCustomPaging="True" 
        
            EnableLinqExpressions="True"

The hierarchy (regardless of how many levels) is displayed correctly and everything works as expected. However, if I turn paging on as using AllowPaging="True", things start to fall apart in that the grid will display two levels of hierarcy for SOME records (when there should be three) and NONE for others (when there should be ONE). In addition, if I have the detail records expanded for all visible parent nodes, some of the detail records aren't displayed until I change the number of results for that page (e.g., from 10 to 20) even though there are only five detail records (when it's set to 10, two are displayed, when I change it to 20, all five are displayed). (This is being changed via the pager control and not via the PageSize setting.)

Here is the code for the radgrid. The datasource is set when the user loads the page and is dynamic. It is not set at markup time.

    
                <telerik:RadGrid

                        </Columns>

                    <FilterMenu EnableTheming="True"> 
        
                        <CollapseAnimation  
        
                            Type="OutQuint"  
        
                            Duration="200"> 
        
                        </CollapseAnimation> 
        
                    </FilterMenu> 
        
                </telerik:RadGrid>

Here's the code behind refreshing the datasource:

    
            protected void grdNotes_NeedDataSource(object source, GridNeedDataSourceEventArgs e) 
        
            { 
        
                        RefreshGridDataSource(); 
        
            } 
        
            private void RefreshGridDataSource() 
        
            { 
        
                        NoteDataProvider noteDataProvider = new NoteDataProvider(WebServicesUri, TicketIdentity.Current.Ticket); 
        
                        List<DisplayNote> displayNotes = noteDataProvider.GetAll(ObjectId); 
        
                        grdNotes.DataSource = displayNotes; 
        
                        grdNotes.VirtualItemCount = displayNotes.Count; 
        
            }

Here's the kicker...when I set PageSize=50 (from the default of 10), all records (there are 24 that I'm working with) appear to show up correctly -- on the all three levels that I'm expecting. When I set PageSize=20 and then run it, I get the same issues as when I set it to 10, only less so.

With that in mind, I believe there's an issue with paging and hierarchy when the number of TOTAL records in the datasource exceeds the PageSize, regardless of where they are in the hierarchy level.

Is this a known issue or is there something I'm missing that's causing me to experience this wackiness? We are using the latest release (2009 Q1) FWIW.

The total record count in the database is 150. If I set the page size to 50, when I get to the third page the child records don't show (nor do the arrows indicating child records are present), however pages 1 and 2 worked fine. If I change the page size to 100 or higher the records with issues originally on page 3+ work flawlessly, but then I get the annoying "This script is taking a long time to run, do you wish to cancel?" error message from IE. It is only when the records get to the third page or more that their correlating child entries stop displaying.

The grid is being bound in the code-behind (Oracle is the provider) using the NeedDataSource event handler. Whenever that event is fired the grid's data source is set to a data table containing the entries (which is retrieved every time that event fires - all records returned according to the stored procedure).

Any thoughts on why pages 3+ would break, but 1 or 2 function fine no matter the page count?
