Hi,
I am just wondering if there any reason why IsBusy property of GirdView is readonly? It would be great to be able change this property to True while loading data from database, then assign the data to gridView.ItemsSource and then set IsBusy to false.
My problem is that database which is used by application might be somewhere in the Internet not in local network. So when I have to fetch a lots of data from DB, it may take about 10 seconds. During this time it would be great to set IsBusy to true and when data are fetched, assign the collection to the ItemSource and resotre the grid. Now it looks like this: UI hangs when fetching the data for 10 seconds and then when collection is assigned the busy icon is animated for about 1 sec.
Could you provide some example how to solve such an issue?
Maybe I can change RadGridView soruce code and change setter of IsBusy to public?
Cheers!

Hello Telerik team,
I am using telerik radgridview in one of my WPF application. When i am binding Itemsource property i am binding a object which has foreign key columns, now in radgridview column i am getting the foreign key ID values as expected.
For example:
Binding Table Colums:
TableID
Name
Description
ForeignKeyTableID (FK)
Foreign key table:
ForeignKeyTableID
Value
Now i want to display the value of the foreign key rather than the id value, as id doesn't make any sense to display. What would be the efficient way to do this. I am thinking of using converter while binding, but it would be heavy as i will be working on thousands of records in radgrid.
Looking for a best and efficient way to handle this...
Thanks,
Kranthi

My RadChart does not display when place in a ItemsControl or a ListBox, when the RadChart is part of a DataTemplate that varies on DataType, no plots of my Datapoints are render. Telerik, what's up with that, why can't RadChart render in a ItemsControl and/or ListBox?.

Hi,
these days I stumbled over the "automatic edit selection" as described here.
http://www.telerik.com/help/wpf/gridview-data-editors.html
Although this looks "nothing special" the mechanism behind it allows us to implement our own editor and register is with the system.
I made a code library post about it since this is a real powerful mechanism.
By the way - congratulations for this - I love it!!
And since I have to proof my role as annoying customer I ask if it wouldn't be possible to implement this also for the "display part" of the RadGridView.
So additional to RegisterDefaultEditor(typeof(myDataType), typeof(myDataTypeEditorSettings)) I would like to see something like
RegisterDefaultCellTemplate(typeof(myDataType), typeof(myTemplate)).
Since in this case there is no need for the complex logic of an editor (with editor settings) a simple "Dictionary of DataTemplates" could do the job. At least in the first step.
Regards
Manfred

Hi,
I am trying to add multiple barseries where each of them also have another serie that belongs to it.
So basically what I want to do is to have the line (or point) value to be directly above or below the bar that the serie belongs to. Right now the bars are standing next to each other (just like i want them to) but the lines or points that are connected to each bar serie is located in the middle of the XCategory and not in correlation with the bar.
I am assuming that this happens since bar are not drawn on top of each other but lines and points are. So if there is any way to prevent this that would be helpful.
What I want to achieve in the end is to show min/max and standard deviation values for an average bar, so in case there are better ways to do this I would be glad to hear about that too.
Thanks in advance,
Mattias

This is my first experience with WPF and Telerik.
When I create an empty WPF project in VS2008, I'm given a Window1.xaml and the outer component is <Window x:Class="..." >
If I'm going to use the Rad controls throughout, should I replace that with telerik:RadWindow? If so, how? When I drag a RadWindow into my current canvas, it is nested. When I run the app, I don't see the RadWindow.
Essentially I'm looking to have a base window for my app that has a RadPanelBar on the left side as the primary menu, and a main content area that will hold multiple windows created dynamically based on menu selections.
I'm not sure what the foundation of a Telerik WPF app should start with.
Thanks,
ms

I have a dataset that is a master/detail, displaying as hierchical data.
The 2 tables are joined on a column called "InvoiceID"
I do not want to show the "InvoiceID" column in the detail data
Without defining every column that should be displayed in xaml, is there a way to specify a column that I want to hide? Thanks

Hi folks -
I am trying to create a multi-ROOM calendar (think mult-day, but instead of say 7 days being displayed, 7 room schedules are displayed). That is, I would like to have several day calendars displayed side by side, where each is the schedule for a single day's worth of events in a particular room.
I have placed several one-day views adjacent to each other, but I still have some remaining issues in order to make the full deal. You can see a picture of where I am at by clicking here: http://bit.ly/13IAYs
1. I would like to remove the forward and back by day arrows and date header information ("wednesday, August 19th, 2009") - just get rid of it completely. How do I do that?
2. I would like to replace the dates in the day header (highlighted in the picture) with the room names. How do I customize those?
3. I would like to get rid of the strange anomaly where the day header is bumped over to the right (Circled in red on the picture). Any ideas what is causing this?
Many thanks
Josh
