Hi,

Anybody can help me,

Currently, groups are sorted alphabetically by their first constituent property definition (eg, if group 1 contains B, C, and D while group 2 contains A, E, and F, group 2 will appear first). Is there a way to control the sorting behavior of the groups-- for example, to sort by the groupname rather than by it's constituents? If not, is such a feature planned?

I need to set those 3 buttons ( navigate left , navigate right and the middle one who opens up a datetimepicker) Enabled = False in some scenarios. I did succed for the left and right navigation buttons by searching through their parents untill i reach the RadScheduleView type (using GetVisualParent<RadScheduleView>()). I dont know why this is not happening for the middle button too. Please help.
Thank you !

Edit : Please let me know if there is a short way to do that instead of my approach.

I'm trying to create a list of charts, widgets, that are being bound based off of data coming back from the database. Given that the DataPoints, ChartType, and also the number of DataSeries are dynamic in every way, I've come up with a solution to use a DataTemplate that has a RadChart object and on that chart I set the SeriesMappings property by running the object through a Converter. The converter then returns back a SeriesMappingCollection, which I thought should be good, but instead the graph plots two points, 8 & 5 which happen to be the Capacity and Count (respectively) of the bound object. We've tried to get this to work for most of the day with no luck. One last thing, we did test to ensure the mappings work in straight XAML and it does, so we were able to rule that out as well. If anyone has any thoughts on this, that would be much appreciated.

RadChart within the DataTemplate:

I have created an attached behavior that allows you to select multiple rows in a grid, edit a cell and upon the edit completing, the changed value is applied to the cells in the same column of the selected rows. This works just fine.

However, setting the grid with SelectionMode="Extended" allows multiple rows to be selected but doesn't allow you to use the mouse to click on the selected row and drag to select more rows. I asked about this and Milan advised to use DragElementAction="ExtendedSelect" which is exactly what I wanted but setting it interferes with the selected rows.

Once multiple rows are selected, clicking on the outlined cell on the current row puts the cell into edit mode (as expected) but all the other selected rows disappear. If I remove the DragElementAction property the selected rows do not change when going into edit mode.

The attached behavior I did does not change the selected rows. I would like to be able to retain the multi-edit behavior and the extended selection drag action. SelectionUnit needs to be FullRow. Any help would be appreciated. Thanks.

I have a applied a template on a GridView row. This template contains a TextBox. When I edit text in the TextBox, the CellValidating event is not fired as would be the case with a non-templated GridView row. Is there a way to wire up CellValidating to a templated row?

In the following example, I would like the RadGridViewCellValidating handler to be called when text in the TextBox in the DocumentRowTemplate is changed. Is this possible?

hi..i build a setup of a project to be deployed which build using sqlserver+tererik(old version) wpf controls in windows xp desktop..it worked fine.
and now i want same to be done in  my win7 ultmiate laptop using new telerik which is present available on air. .. im unable to deploy it..plz can u tell me??

I believe this is quite a common issue.

When I include the Aggregate function for a column in the RadGridView, there is a lot of space between the last row and the footer.  I am not setting any height to the grid.

<telerik:RadGridView AutoExpandGroups="True"
                                  AutoGenerateColumns="False"
                             CanUserFreezeColumns="False"
                             ShowGroupPanel="False"
                             Grid.Row="1"
                             ItemsSource="{Binding Path=Items}"
                               IsBusy="{Binding Path=IsLoading}"
                             ShowColumnFooters="True">

Any clue to how this can be fixed?  I have attached a screen shot of the Grid. 

I am trying to change the last row's row header to have a * in it. Like Access has for the new row.
I have been playing with the Template and the RowStyleSelector but have not been able to achieve this.

For the Template I created the NewRowIndicator but I am not sure what property I can trigger that would be true only for the last row in the grid??

I'm evaluating if your WPF component suite is capable of meeting our needs, and it's beginning to look like a no for the simple reason that I can't even get the tool to display my data. I have the following target:

Get a chart to display 2048 brand new values every 27 ms.

I have attempted this in two different ways, using a RadChart, and using a ChartArea 
.
1) RadChart
This was the first chart that I found that I was able simply declare/assign data to.

e.g. 


 Data is an ObservableCollection<float> which, on a timer ticks every 27 ms, completely changes the data to new random numbers.

The RadChart performed marvelously, except for 1 flaw, it wanted to be fancy, erasing the whole chart and redrawing from left to right the new data. This is not acceptable, as new data arrives so quickly that not 1 data point is plotted before it's wiped again. After scouring these forums for ways to disable this functionality, and only getting "Just set the EnableAnimations to false in the ChartArea" with absolutely no idea how/where this ChartArea is in my RadChart, I opted to making a ChartArea instead.

2) ChartArea
So wanting to disable the animations of the chart, I immediately discovered this functionality:

e.g.

var temp = new ChartArea();

temp.ItemsSource = Data;

temp.EnableAnimations = false;

;

Alas, "No Data Series." ... What? I clearly set it in the exact same way as the RadChart. No combination of DataContext/ItemsSource assigning has resulted in any data points being presented. I'm clearly doing this incorrectly, but am unable after hours of searching these forums to locate such a simple setup as I have defined above. 


Any assistance with this would be greatly appreciated, as I cannot actually test the capabilities of this suite otherwise.
(for clarification, I have tried this via xaml as well, and have had identical results. My code is also being implemented in c# 2010, .net 4.0)
