I am using the tileview and would like to know if the following is possible.
When a tileviewitem is the large tile on the screen (i.e. the other tileviews are all to the right), I want it to have a particular content regardless of how big the tileviewitem is. So if the user makes the application window really small, I don't want the tileviewitem in the large tile to change its content based on the size. I want its contents to remain constant unless it is minimized to the right.
Thanks,
Billy Jacobs

I am binding my RadGridView's ItemsSource to a System.Data.DataSet. This dataset is readonly and is not interpreted by my application... it's just obtained and displayed for the user to view. It comes from a web service and the idea is that this web service may change the contents being served up in the future. The number of columns in the dataset may change down the road.
There is one important exception to this. Once my application obtains the dataset from the web service, it adds a column onto it and populates it with objects of a complex type.
In my gridview, I'd like to display these objects with much more than just the default ToString.
I'd like to use a DataTemplate to do this.
I see the GridViewDataColumn's CellTemplate. But I'm not defining GridViewDataColumns in my RadGridView, because, as I mentioned, I'm binding the GridView's ItemsSource to my DataSet. So, at least at first glance, that doesn't seem useful to me.
In addition, I'm using the MVVM application model. So although I'm tempted to drop the binding to the ItemSource, manually add a GridViewDataColumn for each of my columns, and set the CellTemplate on my special column, I'm resisting the urge. Ideally I can do this all with binding.
How can I apply a DataTemplate to my cells while still binding to ItemsSource?
I wish I could specify a CellTemplateSelector for the entire GridView. Then I'd just apply a special template when the cell contained an object of my type.
Thanks for any help.

It looks like a bug in System.Windows.DataTemplate, but I thought I'd ask here if you know a way around this bug:
Assigning a ToolTipTemplate to an InformationLater requires that you pass it a DataTemplate (of course - for binding), but the DataTemplate tip does not support CornerRadius (it seems broken).
However, if I omit ToolTipTemplate and use ToolTipservice to specify this and call a ControlTemplate for the tip, CornerRadius works fine!
Any idea why this is or how to work around it easily?
Thanks!

Hi,
I am trying to automate the controls in subject. The site below tells me UI automation for these controls are not supported for wpf applications. Is there an update/recommended solution regarding the same that I can leverage for my UI automation? It may save me a lot of time :)!
http://www.telerik.com/help/silverlight/ui_automation_support.html
More information on my work around and where I am stuck:
- DateTimePicker control
Please see attached image for reference. Using UI Spy I can actually see the window and all of its content for the “date” control. The automation ids are missing, but at least I see the “window” control exposed and the ‘text’ names that I can actually use in my helper function to get/set a specified date.
However, the clock portion of it is hidden from UI spy. I don’t know if this is another window control or something that is just embedded in the date window? Any ideas on how I can access the clock window?
- RowDetails control
This is not exposed at all in UI Spy L! I am thinking of a work around that I have not yet tested but before I invest time in it, I was wondering if you have a recommended solution that I can use?
Thank you for your help and time,
Harleen

I want to create rowdetails in behind code page because the contents displayed in rowdetails are vary according to the value of each column in one row. I read the example about this from telerik but it is defined when initialize not runtime. So anyone can suggest me how to do it in behind code.

Hi,
I have just download build 2009.2 813 which fixed an issue we were having, however it has broken something else.
If a Grid has no records in its item source and the ColumnsWidthMode is set to FIll I get the following exception:
Message="'-3' is not a valid value for property 'ViewportSize'."
The xaml code for the Grid is:
If I change the ColumnsWidthMode to "None" or "Auto" it works fine.
Regards,
Glen

I found two problems with zooming a line chart:
1) Clipping of data points
Let's say I have 5 points at x = 1..5. If I zoom to x = [1.5, 3.5] the line is only drawn for the points with x = 2,3,4. What i would expect is, that the line is interpolated from x = 1 to x = 2 and drawn starting with x = 1.5...
This is not only true for zooming but for drawing in general (e.g. manual axis).
If no data point is with the specified range, the line is not drawn at all. Instead i would expect the visible sector of the line is drawn.
2) Visibility
I set the visibility of some series using
| _diagram.DefaultView.ChartArea.DataSeries[myIndex].Definition.Visibility = false |
However, after zooming or scrolling, all series are visible again.
3) If at least one series has no data in a zoom range, zooming is not possible at all. (see 1)
Please fix this in an upcoming release.
Kind regards

hey! guys:
I created a datatable by code and set it to gridView's itemsource, everything looks good ,I could grouping cols my drag it to group panel.
then I created a button, in button's behind code, I created some group descriptors and added them into grid's group descriptors, Oops,
the problem is coming , the grid is not grouped as I expected, some rows were missing.
After I deleted the group cols by closing the grouping button and drag cols into group panel, the group is ok again.
The codes is same as demo. Did I miss something ?
