Hi,

we updated our Telerik Windows Forms to version 2010.1.10.504 and now I have the problem that the RadGridView looses its theme. I have to say that the Telerik dlls are lying on a network share, maybe that causes the problem, because when I use my locals dlls (version 20.1.10.409) everthing works fine. The funny thing is that in some rare occasions the theming works fine, without changing anything, only restarting the application and further it concerns the gridview, only. Other controls like the calendar are themed correctly.

Best regards

Martin

Hello,

I've recently discovered what i think is a bug in the Size Changed event of the form, whenever i change the size of the form the event fires twice. I can't attach a demo here but it's easily achieved, just by creating a RadForm and using a messagebox on the SizeChanged event, it will fire twice, and not only that, it will fire even when the form first starts (this does not happen on normal windows forms)

I've also submitted a ticket on this problem with id 316570, if someone had the same problem please let me know

Thank you,
Emanuel Varga

Hola, utilizo la version 2009 q3 con sp1 para winforms y tengo un problema al enlazar un datasource al radcomboBox
tengo un datatable llamado dt cuya consulta sql es : "Select id, nombre from cuentas"
suponiendo que tengo un radComboBox llamado cmbcuenta


cmbCuenta.datasource = dt
cmbCuenta.displaymember= "nombre"
cmbCuenta.valueMember = "id"

En la ejecucion de mi programa el nombre se ve perfectamente y en el evento selectValueChange programa que en un textbox se vea el valuemember de la cuenta que me selecciono. Algo como esto:

miText.text = cmbCuentas.valuemember
El caso es que no funciona el "id", asocia bien el nombre pero al poner id en miText.text se coloca la palabra "id".
Alguna sugerencia?

Hello,

Hi,

I'm displaying several type of classes using the BindingList class as a DataSource. The GridView automatically generates columns of the names of the properties defined in these classes. In this case te text of the columns can be set with the DisplayName attribute. So far so good. My question now is, if there is a way to  change the order of the columns via property attributes and/or if it is possible the hide some properties from beeing displayed. 

Thanks in advance

Hi,

        I have custom appointment class and as well as custom editappointment dialog. I am able to reproduce Daily recurrence and weekly recurrence in the radscheduler. But when i try to create exceptions for the Appointment,  the radscheduler control displays daily recurrence even for the days which has been defined as exception.i am using SchedulerBindingDataSource. 

I am new user for Telerik , recently learning RadGridView tutorial --> Hierarchical Grid --> GridViewBinding to Hierarchical Data
I do as tutorial, when arrive at "Define Relation" I can't find "GridViewRelation Collection Editor" as shown in tutorial.

Pls,
Is there anyone can tell me where I can get "GridViewRelation Collection Editor"?

Thanks and Best Regards
