Hello,

Is it possible to bind multiple series to one chart but with different data sources ?

I'm having a case where I need about 6 line series on the chart but they have complitely different data source.

Is there an example ?

I'm planning on using the latest (Q2 2011) WPF version on .NET 4 (evaluating the trial currently). 

Thanks!

Hi,

I need to find RadRichTextBox which contains RadDocument of DataField (custom that I created)

Since updating to the Q2 2011 version just recently, I find that none of my applications that uses the Tererik controls work, nor can I create a new app and add Telerik controls to it.

Here is a simplified Test Case:
I created a fresh WPF application project, opened the MainWindow.xaml, and tried to drag a RadMenu onto it.
It throws up this Error Dialog:

Set property 'System.Windows.ResourceDictionary.Source' threw an
exception.

"Cannot locate resource 'themes/genericmetro.xaml'."

OK

I'd like to know how the Telerik RadControls for WPF installation works, so that I can understand a bit of what's going on. The installation folder, in C:\Program Files (x86)\Telerik, has a folder that would seem to be an older version: RadControls for WPF Q3 2010 SP1\Binaries\WPF\and so on.

Within AppData\Roaming\Telerik, I see an Updates folder with various folders for hotfixes. And the csproj file contains hintPaths that point to these. So, clearly the hintPaths are trying to redirect VS to find the latest versions of our assemblies. Is this the mechanism that is not working here?  Would it help to just un-install Telerik, and reinstall something that is the latest version with the hotfixes already rolled into it?

Thank you for your help,

James W. Hurst

Hello,
I'm having a problem with the display of error messages on validation on a RadGridView.  I use property level validation implementing the IDataErrorInfo interface on my entity classes and the RadGridView correctly reconnizes when there are errors in the entity properties, however it rendered the errors that are present at databinding and the errors that occur due to user editing quite differently.

When the RadGridView is populated with data that already fails the validation rules at the time the data is binded, the grid displays what I consider a nicer looking error template that contains a red triangle in the corner of the cell and highlights the cell in red.  However, when the user edits a cell/property value to a value that is invalid according to the property rules they see another style of error notification that is a simple red box around the cell without "niceness" of the other error.  See attached files for the comparison.

Is there a way to get both types of errors to use the "nicer" error notification template?  I can't seem to find out how to do that.

If I have a Day View which has an orientation of horizontal, how can I reduce the height of each resource row?

I can find a way of reducing the appointment height but cannot find a way of reducing the resource row height.

Would appreciate any help you can give me.

I've removed the row header by setting the RowIndicatorVisibility="Collapsed" property on my RadGridView. I notice that there is a gap between the gridview border and the first column cells. There also seems to be some sort of gradient effect to the left of the first columns cells. How can I remove the pixel-gap between the border of the grid and the first columns cells? I would also like to know if its possible to remove the aforementioned gradient effect.

My grid is styled with the office blue theme (StyleManager.Theme="Office_Blue")

Hello,

I recently upgraded our distribution to Q2 2011 and everything works great except for dragging and dropping. I currently have a scenario where I am dragging from a ListBox to a RadChart and it still "works" but doesn't show the drag que arrow anymore. I added the following line to our code:

RadDragAndDropManager.ExecutionMode = DragExecutionMode.Legacy;

This had no discernable effect. Also we now get an intermitten crash:

The specified Visual and this Visual do not share a common ancestor, so there is no valid transformation between the two Visuals.

This error occurs while dropping onto the RadChart. We have been using this code since mid-2010 and has survived at least 3 upgrades so the problem (since it seems Telerik has extensively changed the RadDragAndDropManager and divided it into 2 parts) may lay in the fact that we need to upgrade the drag and drop code. The problem is I have no idea what to change since the documentation seems to be almost verbatim what the last documentation set had. Any help in resolving this would definitely be appreciated.

Edit: I was just testing this and I remembered that I should say that the ListBox is in a RadDock and when the tab is pinned it works fine and doesn't give the visuals error. If it is unpinned it crashes. Once again, it worked fine before the Q2 upgrade.

In the RadGrid how can I determine if the user changed the value of the data in a grid cell? I'm using WPPF and MVVM.

Hello,

I have a Gridview that is bound to a Observable Collection which contains about 240 rows of data.  When I drag a column to the Grouped By header, it groups the records as intended in the group footer.  In my application, this Gridview is located in a Tab.  Now when I tab to another screen and come back to this Tab that contains my Gridview, the gridview is refreshed with data.  The problem I am experiencing is after the refresh, the amount of data in each group footer, there is now only one record in each group, though the bound collection still has it's 240 records.  Anyone have any ideas what I am doing wrong? or is this a possible bug I might not be aware of?

Thanks for any help,
