Hi, when using the grouping feature can I select the grouping row..
In other words can I have the Grouping Row have cells that I can interact with ?

Thanks
kristján.

I want to change all the grid cells' background. Using SpecialSlotStyleSelector is the only way. Is that true?
I have setted  StretchAppointments="True" in TimelineViewDefinition. There are still some blanks at the top and bottom (see the attach) for the appoinement item. How can I grid rid of them.
Thanks.
Merry Christmas!

If I just want to have the right page, would that be possible?

Hi,

I've reviewing the new ChartView control (from a background of using the previous Chart control) and I'm wondering what is future plan for displaying chart legends? The existing Chart control had built-in support for legends, however I'm noticed that the ChartView examples manually build legends. Are there future plans for a related control to display a legend or provide some support for legends in the ChartView control (I personally like the idea of keeping legends out of the ChartView control to keep the control as light as possible) or should we as developers expect to build our own legends? I just want to understand Telerik's future plans so I know whether to invest time in building my own legend control or simply build something quick because Telerik will provide support for legends in some form in a future release.

Kind regards,
Dave.

My customer requires grid cells to be joined vertically. This information must be updated whenever the grid changes, e.g. sorting/filtering updates of the underlying data. I now have the problem, that my grid contains the correct information but it is not redrawn with the updated information. the cell joining information is not on the objects contained in the list, but in a dictionary in the background. I am calling the method to update my dictionary when the grid is sorted. The grid is redrawn sorted correctly, but my information in the background is not up to date, so the cell-joining does not work correctly. I've tried various ways to have the grid update (also within the sorted event) but no success.

I've tried:
grid.InvalidateVisual();
grid.Measure(new Size());
grid.Visibility = Hidden -> Visible;

I've also tried the same on the parent element (a normal grid).

The thing is, when i hide the area where the problem is, then resize to show it, it's how it should be. so the data is up to date, but i can't seem to force a redraw at the right time.

I somehow need to force a redraw after the data has been updated and the sorting is done. any help much appreciated.

I have managed to get an update working, not so nice though. i am using DispatcherTimer to redraw after 10milliseconds. there is a visual jump though. but it does show that the underlying data is correct. I've also just noticed that my grid joining does not work, when items are removed/added to the list. what event on the radgridview can i use to find changes to the list (or even better the changes to the items in the list). I noticed LayoutUpdated does the trick, but it's mighty slow/called way too often.

I have a RadGrid where the user is supposed to select more than one item (multiple). In the ViewModel I have a property called _SelectedItem with NotifyPropertyChanged. First time i click a row in the grid, I get into the _SelectedItem property setter, but if I also want to select another row, the setter of _SelectedItem property is not fired. Am I missing something? CodeBehind is not allowed in the project where this is to be used.

This is my Grid:

Hi!

I was testing out the following tip: http://www.telerik.com/help/wpf/radchart-howto-display-pointmarks-and-labels-for-specific-points-only.html

It was working perfectly with my small dataset for testing but then once I tested it with a larger dataset it didn'n work anymore. After a bit of testing it seems this feature only works if the dataset has less than 200 datapoints. As soon as you reach 201 the DataItem is no longer attached to the pointmark. Why is this and is there a way around it?

We are using a RadRibbonWindow in an application (running on Win 7). When the application starts, there is a lot of black areas where comtrols (RibbonBar, tabs etc.) normally are placed, and when moving the mouse pointer around in the RadRibbonWindow, the controls are showing and the black fields disappear. This also happens if i by using the mouse drags the window so it's size gets smaller or larger.

The problem started after i upgraded to version 2010.2.812.40 of the radcontrols. Is this a bug, or is there something i have missed?

Hello,
I'm using an MVVM pattern in a WPF application with RadDocking ... I've got some RadGridView inside usercontrols and they perform poorly with horizontal and vertical scroll... I've searched this forum and the problem seems to be a missing height/width on the RadGridView... since I've defined in me Shell a 1024*768 width have I for each UserCotrol to specify a default width/height? how can I set it to the parent content?

I've also some master/detail gridview that uses a behavior to fill the child RadGrid...those performs worst... have I to specify an height/width as well?

Thanks

Paolo

I've written a module to export data from a WinForm RadGridView to excel. The module handles grouping as well. 
Now that we have ported over to WPF, that module doesn't work anymore.


Below are the RadGridView Winform objects, properties or methods. What are the equivalents in WPF?
GridViewChildRowCollection
GridViewRowInfo
row.ChildRows
row.Group
row.HierarchyLevel
row.Group.GroupRow.HierarchyLevel
DataGroupCollection
DataGroup
group.Groups.Count
grid.ColumnCount
