How do I implement many to many editing in radgrid using entity framework and declarative techniques? I have looked all over for examples.

my case is very simple with the following tables: Student, Class, StudentClass with StudentClass being strictly defined by Student.ID, and Class.ID

Entity framework turns this into Students with a Classes navigation property and Classes with Students navigation property.

In radgrid I want to display the classes for a given student, thus creating a localized master-detail or 1 to many view. unfortunately I can't pull it off, perhaps because not fully understanding the navigation properties and independent association, StudentClass.

I created an EntityDataSource against Students. I associated it with the StudentCourseRadGrid. in Master table View --> Columns, I have a bound ID (Student) column, and a dropdown Courses column. After that, things fall apart. Once I select the student, its id appears in the grid, but not his courses.

And then, of course, I want to be able to crud the StudentClass relationship. I fully expect to handle the radgrid_insert event which I have done easily in 1 to many scenarios.

this is the section giving me the most difficulty - it is wrong - very wrong.


I have tried many other permutations involving DataSourceID, ListTextField, ListValueField, and DataField, using Courses reversed with Students,without success. The only examples I have seen are hierarchical but I don't consider my situation hierarchical and it only confuses matters.

Any help is appreciated.

PS - after thinking about this, I believe that I tried to oversimplify the problem. 1 dataset is required to display the Student, 1 dataset - perhaps a navigation property though not sure how - is needed for the student's Classes, and 1 dataset is required to provide domain values for the StudentClass relationship should tuples be added. it will require more custom coding than wanted, but it is the logical, approach. I would be interested in something more efficient but for now I don't see it.

i have edit/delete auto-generated coluns activated but it shows as a text edit and delete and automatically retrives the info.
how can i have instead of the texto na icon.

i tried this but this gives me na js error saying that need page eventvalidation true.

so there must be a way to but na image in edit delete instead of text

Hi,

thank you!

Hello,

I'm using the css found here: http://www.telerik.com/support/kb/aspnet-ajax/scheduler/auto-expand-the-height-of-the-appointment.aspx to have appointments expand to show the whole appointment subject in the month view. This works perfectly on my local machine but whenever I put the application onto a remote server I get some odd behavior. If there are appointments present on a month view and I move my mouse over any part of the actual calendar a scrollbar appears even though I have the scheduler set to Auto-Expand Mode true. Any suggestions?

Thanks,
Matt

I'm using an ASP.Net RadDateTimePicker (2013.2.717.35) and trying to set the displayDateFormat as the user is selecting a new date or time.  If the time is 00:00:00 (midnight) then I want to display only the date.  Once the user selects a time other than 00:00:00, then I want to show the date and time.  I'm trying to set this format in a JavaScript function that is wired up to the ClientEvents.OnDateSelected event.

The issue I'm having is that the formatting of the date/time value isn't applied to the date/time the user just selected.  It gets applied to the next date/time the user selects. For example, when the user clicks on the calendar icon and selects an initial date, the value is, for example, "08/06/2013 12:00AM".  The ClientEvents.OnDateSelected fires, I see that the time selected is midnight so I execute the following JavaScript to hide the time portion:

After the OnDateSelected event finishes, the "12:00 AM" is still visible.  If the user then clicks on the clock icon and chooses a time other than midnight, then the following JavaScript line is executed in the OnDateSelected event:

At that point, the user sees the formatting selection from the previous event firing, which is "08/06/2013".

How can I correctly intercept the date/time the user selected and apply the proper formatting immediately?

Here is a sample page that I'm working with:

How does one add a rounded bottom to one of the drop down navigation windows? I was working away at .RadMenu_Metro .rmGroup (I am working from the metro template) and am able to set a static height, but adding a bottom padding or something similar to add a background image just isn't working. Is there a way to do such things without styling another clickable button? Not all of my sub menus are the same length and I would like them not all to be.

I want something similar to this: http://blog.karachicorner.com/blog-images/039/jquery-menus/jquery-drop-down-menus-1.jpg
(again, just looking for the rounded corners on the bottom of the drop down menu)

Hi 

I'm struggling with the last part of my drag drop functionality. I want to drag from a grid row (no problem there) and drop onto a LinkButton or preferably any html element within a RadListView. 

My page has a RadListView which has a number of dynamically created Tables, Table Rows, Table Cells and LinkButtons. When dropping the grid row on the LinkButton I can see the dragged element and also the e.HTMLElement is populated with the name of the LinkButton e.g. ctl00_MainContent_lvEngineers_ctrl0_lbtnTeamLeaderMeeting however I cannot seem to use FindControl to get the LinkButton, whatever I try returns nothing.

This page is within a Master page. I've tried rebinding the ListView, tried using FindControl on the RowDrop, Page_PreRender but no joy.

Many Thanks

Steve

When i use  Grid.MasterTableView.InsertItem() to add a new row to the Grid and FrozenColumns > 0 user cannot tab past whatever is already showing in the screen.
I've used the following workaround when the user is editing the item but it does not work when new rows are inserted. Is there anything else i can do about this?

Hi, on the Demos , there is a bar near the top with the Prev/Next Demo buttons, the Rate/Review link and the Skin link. The rate / Review and skin both drop down a panel and have an extra button for closing, and also allow only one to be open at a time.

What do you use for that functionality?

Im looking to implement something nearly identical to that and the PanelBar doesn't seem to quite fit the bill.
