Hi,
In your latest trial available build, there exists a problem, here I describe:
I have a WCF service which I retreive data from and then fill the ObservableCollection with them, this collection is the one will be set to ItemsSource of the grid.
In the process of filling the ObservableCollection, first I call Clear() method and then add new data to it.
Now steps resaulting to the Exception:
1- Set data to ItemsSource of grid
2- In the grid scroll down (not necessary to the end)
3- Do something to force data update (Next page, Edit, ....)
4- Oops, the exception! (This exception as is clear in the following lines happens when I call .Clear() method of ObservableCollection
Note that I have resolved my problem by first assigning null to the grid ItemsSource, then updating ObservableCollection and then reasign the ObservableCollection to ItemsSource :D
here is the detailed exception:
| System.NullReferenceException: Object reference not set to an instance of an object. |

Now I have different colors as rowbackground depending on value in "category". but how can I use images (horizontal tiled) as background for my rows?
How I do it now:
How I do it now:
| <Style x:Key="GridRowStyle" TargetType="telerik:GridViewRow" |
| <Style.Triggers> |
| <DataTrigger Binding="{Binding Path=category}" Value="1"> |
| <Setter Property="Background" Value="#FFFF88" /> |
| </DataTrigger> |
| </Style.Triggers> |
| </Style> |

We are using context menu with tree node. The tree and context menu are both dynamic and binds on the runtime.
The tree has several levels of nodes and context menu is specific to the nodes at different levels.
The tree supports the multiple selection.
As per our requirement, we need to find multiple selected tree nodes when the user right clicks on any one of the mulitple selected node to open the context menu.
1. Single node selection
When we right click on the single node to open the context menu, the node which was right clicked does not get selected. We have used the following piece of code to identify the node which was right clicked, and it gives us the correct value.
private RadTreeViewItem ClickedTreeViewItem
{
get
{
return radContextMenu.GetClickedElement<RadTreeViewItem>(); }
}
this
.ClickedTreeViewItem.DataContext
2. Multiple nodes selection
In case of multiple selection, we have to select the nodes and we are not able to find the nodes which are selected while using the context menu.
To summarize:
1. We need a way to find the selected nodes in a tree on right click to open the context menu for either single or multiple selection of the tree view item.
2. The node on which the context menu was opened should be selected as well.

I have a numericUpDown control in a gridview and when I click on one of the arrows, the arrows go away and the cell isn't in edit mode anymore. Any help is appreciated.

I am planning to use telerik on some scientific application where we plot a lot of data, and since there is huge amount of data the plot will be a "summary" and "detail" chart where the summary plot will have a summarized value for, say, each minute over a longer period of time and a detail plot will lot the value of each minute's worth of data when the user selects that particular minute.
Now, I am planning (or at least the requirement says) that the summary plot have a movable ( and i am not sure if this is the correct term but) vertical cursor, which can be dragged by the user from one point to point and this event is to trigger the details plot for the corresponding point the user rests at.
I have attached a portion of a screen capture of the summary plot. The orange line in the picture is to be the cursor.
Does anyone have any idea how to do this in telerik charts for WPF? Does anyone know if it is possible?
Thanks a bunch..

Hi,
I have a Gridview and a Chart. The gridview can be filtered. what i would like is the chart to update its view based on the filter applied by the user but I cannot see how to bind the chart to the filtered list.
//Load data and bind to gridview
I have a Gridview and a Chart. The gridview can be filtered. what i would like is the chart to update its view based on the filter applied by the user but I cannot see how to bind the chart to the filtered list.
//Load data and bind to gridview
ObservableCollection<People> peopleByYearData = GetPeopleByYear();
gridViewPeople.ItemsSource = peopleByYearData;
//this displays the data on a simple bar chart.
chartPeopleByYear.ItemsSource = gridViewPeople.ItemsSource;
How do i ensure that the chart updates its view when the gridview is filtered?
i have tried hooking into the Filtered event of the gridview to try and get access to a list of filtered items but I cannot find any such list. The filter displays fine on the gridview but in the Filtered event the gridViewPeople.Items.Count is always == 0.
Thanks

Hello,
I have a question about licencing. I work in company where is few development teams, each team for different project (client/server development). One team is working on project with GUI (project A), this project will reference Telerik WPF controls. Another team is working on project B which reference project A.
The question is, do i need licences of WPF controls for developers on project B?
Thanks

I am trying to print a RadGridView control.
I followed the sample provided, creating a new control and I do see pages of data from my grid... but here's the issue...
It seems like the good layout stuff must not be happening. My alternating colors don't show up. The text wrapping is not happening. My columns are never resized to fit the width of the printed page.
My theory is that because my print grid is not part of the visual tree, it never gets the Loaded event where all of the good stuff must be happening.
Please help if you can :)

I'm trying to use the FilterOperatorConverter class for the Filtering Dialog, and keep getting a Not Implemented exception for the ConvertBack method of the converter. A quick check with Reflector shows that the FilterOperatorConverter.ConvertBack() method does indeed throw a Not Implemented exception. Base on the released documentation, the FilterOperatorConverter.ConvertBack() method is documented as able to do the conversion.
I need to override the template & style for this Filter Popup in the RadGridView. How would I overide the style and template in the Combobox dropdown of the FilterOperators so that the Text for the selection appears as "Is Equal To" rather than "IsEqualTo"?

When the minimize button is clicked, the RadWindow hides the content within it (See attachment). Is there a way to minimize the window to the taskbar? I'm using Q1 2010, this didn't occur in Q3 2009. Thanks.
