Hi,

I'm using
The RadGridView v. 2011_2_0712 of the Telerik Controls
Ado.Net Entity Framework 4.1
VistaDB 4.2.18.4 or MSSQL Server 2008

I'm trying to bind a simple RadGridView to a model and then to use the built-in functions.
I have two identical test projects and two identical sampleDBs the one is in VistaDB and the other in MSSql. In the first project I use the Entities from the model generated using the VistaDB and in the second project using MSSql. 

The binding is done like this in both projects.

The Sql script to generate the tables is like this.

Summary:
Project 1
- RadGridView
- Ado.Net 4.1
- Model from VistaDB

Project 2
- RadGridView
- Ado.Net 4.1
- Model from MSSQL

The two DBs are generated with the same script and seem to been exactly the same. The generated models are exactly the same. BUT when I try to group columns in the project 1 then an exception is thrown. In project 2 the whole grouping, sorting and filtering functions are done well.

Anyone knows about issues of the RadGridView with Ado.Net or with VistaDB?

If it's requested can I upload these two test projects.

Thanks in advance
Walter

Are you planning on making it possible to place into a RadDocking instance other RadDocking instances?

Hello,

I have a need to set up grouping by both a person's name and what location they work at.

The end result of what i am attempting to do is to have it selectable what person(s) and what location(s) you want to select and then show them on the grid, the catch is that some people only work in 1 location while some work in many.

For example  if we have Person A, Person B, Person C.  Person A works at Location 1, Location 2, Location 3; Person B works at Location 2, and Person C works at Location 3.

so the grid header would look something like:

                         Person A                           Person B         Person C
   Location 1    Location 2    Location3       Location 2       Location 3

I would have 5 columns total,  i have tried adding these as ResourceGroupDescription's in a GroupDescriptionCollection to the ScheduleView.GroupDescriptionsSource, and the resources to the ResourceTypesSource, but when i run it i end up with 9 columns, it makes a location1, 2 and 3 for each Person.

So can anyone tell me the correct way to make it only have the 5 correct columns instead of all 9?  Thank you.

Hi,

In Scheduler Control it was very easy to handle the different cases of events.
I have the following problem in SchedView Control:
When the user "doubleclicks" an appointment then ShowDialog-Event is fired. In my case I set "e.Cancel" and I have my own dialog to Edit the data of the appointment. Fine!
But when the user user deletes an appointment (per single-click on the cross-symbol in the right corner) the same event (ShowDialog) is fired (before the Appoint_Deleting event is fired !!!!!). I cant´t find a solution to handle the difference between these cases (Edit or Delete) inside the ShowDialog-event.
I´m also missing the ShowsConfirmationWindowOnDelete property from Schedule-Control in ScheduleView-Control to suppress the default dialog and show my own dialog.
Thank you in advance.

Regards,
Stefan

After i changed the size of the items (ColumnWidth and RowHeight), i get 
sometimes an ArgumentException when I reorder items per drag-drop.
For the DataTemplate, i use a RadFluidContentControl 
System.ArgumentException: '-42,-42,-42,-42' is not a valid value for property 'Padding'.

Hello,

I was wondering if there is a way to check if a GridViewDataColumn's filter... is active or contains filtering.  I have code that will execute depending if the column has filtering on or not.

Thanks,

Hi,

I'm using WPF version of Chart component.

How can I get series value in the given X-axis location?

E.g. X-axis type is datetime and Y-axis type is double. So if I want to know series (y) values in specific time, how can I do that?
