Hi,
I have few questions about how to create custom item in RadListView.
I have a list of objects and would like to create custom item for each of the object. The value of visualElements of each custom item will get from properties value of associated object.
By reading the online documents, I know that the custom visual item is created by caling VisualItemCreating event. But how can I trigger the event?
As I understand the function SynchronizeProperties() is used to assign values to visualElements when the custom visual items are created (please let me know if I am wrong). In the example code, the value assigned to custom visual item are from data table. But In my case I want to assign the value of properties of a object from the object list to each custom visual item. What steps I need to go through to achieve that?
Thanks a lot

Hi, everyone,
I have been using telerik controls for windows for few months now, and this may be a stupid question. I've noticed that when a radgrid has been filtered or sorted, the SelectedRows property shows only one row selected even though more than one has been selected. I had a piece of code that uses that property so that on the edition of one row the value is copied to the other rows.
Here's a sample of my code:
Is this the default behavior? If so, is there a workaround so that I can persist the selected rows programmatically and keep my code as it is? I am using version 2011.02.712.
Thanks for your help,
Mauricio.

If so, is there a workaround so that I can persist the selected rows programmatically and keep my code as it is? I am using version 2011.02.712.

Hi,
When user drag an appointment to another hour, i want to do a validation to verify if that hour is prior than current date. The only event i see i can do that is in AppointmentFormatting, beacuase in CollectionChanged there is no changes in this case. However, it isn't possible to show a messagebox in AppointmentFormatting (gives an exception "Target invocation ...").
So my question is: how can i validate when user drag an appointment to another hour an show a messagebox to warn about this validation.
Thanks.

I am adding tiles to the control in code and they draw right on top of each other. I don't really want to manually specify which row and column it needs to go into. Is there a method for setting those properties automatically?

Are there any useful documents detailing the relationship between deprecated components?
E.g.
RadPanel = RadPageView
PadPanelItem = RadPageViewItem
etc.
RadPanel.Items becomes... PadPageView... ?

I know you can add agrregate totals to the group headers, but I was just wondering if you can easierly add a Subtotal Row to the bottom of the group, as well as an Total to the whole table?
If there currenlty isn't, can I suggest this as a Feature Request, as it would be really handy, and Also is there currenlty any code samples to be able to do this?
Thank you

Hi
If I use separate scroll bars for chart, then my UI does not look good since either the chart or the x axis labels are overlapped with the separate scrollbar, Instead can i use the radchart scroll bar itself?
If i use the following I am not able to see the scrollbar on the chart.
radChart1.VerticalScroll.Enabled =true;
radChart1.VerticalScroll.Visible=true;
radChart1.HorizantalScroll.Enabled =true;
radChart1.HorizantalScroll.Visible=true;

Hello,
on this screenshot :http://tc81.net/private/telerik/20111202_1554.jpg
How can I remove that stuffs that's hiding a part of the word 'Contacts' ?
I think I found a way which is to hidden to set visibility:hidden for the first contextualTabGroup, and start to use at index 1 instead of 0.
But I'm not sure if that is the "clean" way to do it.
Thank you.
