Hi,
I have a gridView with RowDataTemplate which has a UserControl:
            <telerik:RadGridView.RowDetailsTemplate>
                <DataTemplate>
                    <CptyManagement:CptyView DataContext="{Binding}"/>
                </DataTemplate>
            </telerik:RadGridView.RowDetailsTemplate>

I'm trying to get the UserControl instance of the selected row.
I get the selected row by
var row = (GridViewRow) gridView.ItemContainerGenerator.ContainerFromItem(gridView.SelectedItem);
But I couldn't get the UserControl from the Template.

Can someone help?
Thx,
Oren

Hello,

I am using your (great) RadWindow. The problem is when i set its Flow property to 'RightToLeft', when i try to drag it to the right for example, it 'flies' real quickly and vanishes to the left, without the possiblity of focusing it again. When removing the RightToLeft , everything is back to normal.

Please help!

Thanks,
Oran

I'm trying to create an effect where sometimes elements of a RadChart are hidden, but I'm having problems on the Axes (X and Y). I would like to hide everything BUT the title on the Y Axis, and hide only the title on the X axis.

My problem is that this seems impossible to do through XAML, and the examples seem convinced that I'm using Expression and codebehind. I'm not, and I'm not, because charts may not be instantiated when this effect occurs, and will miss the event.  I'm bewildered by the various properties and classes for supporting an Axis. What is the difference between AxisYStyle, AxisY.Styles, and AxisYItemLabelStyle? The RadCharts' Axes seem to ignore whatever style I place on them, and the only way I'm seeing to achieve my effect is to hardcode it into the XAML, which is not what I want because this effect is supposed to be conditional.

Hi,

 

I have a Pie Chart and the following code:

 

 

What I would like to do is to “pre-select” an item immediately after generating the chart. However, the SelectItem in my code doesn’t work because it seems the SelectItem needs the chart to first be rendered. If I call the SelectItem from a timer (and then the chart has been rendered), then it works. Is there a way to call the SelectItem when the chart hasn’t been rendered? Or is there a way to know when the chart and the different elements  have been generated so that the SelectItem will work?

 

Thanks!

Regarding grid view control, the "First Look" example shows a tab control for each row. We can also have a hierarchical grid as shown in "Custom Hierarchy" example. Can we have a grid for both functionalities together? Like we can goto 3rd level hierachy and on this level, we provide a tab for each record.

Hello!
Found one problem with radgridviev, which I dont know how to fix.

My scenario:

WPF app for .NET Framework 4
Windows 7 (x64) Ultimate
Version of Telerik dll's: 2011.1.419.40

Here's a structure of document that i'm querying from data source:
Client 
-- Animals
----- Receptions 
(there's other relations like Client - Contacts and so on...)

I show the data to user using the following hierarchy:

RadGridView (showing clients)
-- TabControl
----- RadGridView (showing animals)
---------- TabControl
--------------- RadGridView (showing receptions)


Now, for the problem:

Every RadGridView in hierarchy has handlers for: SelectionChanged, Deleted, RowEditEnded. 
When i add any of SelectionChanged, Deleted, RowEditEnded handler to receptions RadGridView my app shows only the clients grid (the topmost one) with "+" that's not expandable.
Without handlers everything (in leaf RadGridView) works as expected.
If i use a debugger it shows that i have exception: NullReferenceException that's throwed from GridViewRow.OnIsExpandedChanged.

Here's a part of xaml i use :

Any suggestions about what am i doing wrong?

EDIT: 

if i delete "RowStyleSelector="{StaticResource ReceptionRowStyleSelector}" and add handlers to my nested grid - then all seems to work again an there's no exception. But i have no row styling for grid.

That's my ReceptionRowStyleSelector code:


Styles i use a very simple:

<local:ReceptionRowStyleSelector x:Key="ReceptionRowStyleSelector">
            <local:ReceptionRowStyleSelector.DefaultStyle>
                <Style TargetType="telerik:GridViewRow"></Style>
            </local:ReceptionRowStyleSelector.DefaultStyle>
            <local:ReceptionRowStyleSelector.CompletedReception>
                <Style TargetType="telerik:GridViewRow">
                    <Setter Property="Background" Value="#4502FF49"/>
                </Style>
            </local:ReceptionRowStyleSelector.CompletedReception>
            <local:ReceptionRowStyleSelector.CanceledReception>
                <Style TargetType="telerik:GridViewRow">
                    <Setter Property="Background" Value="#40000000"/>                
                </Style>
            </local:ReceptionRowStyleSelector.CanceledReception>
            <local:ReceptionRowStyleSelector.NotifiedReception>
                <Style TargetType="telerik:GridViewRow">
                    <Setter Property="Background" Value="#4FA4B700"/>
                </Style>
            </local:ReceptionRowStyleSelector.NotifiedReception>
        </local:ReceptionRowStyleSelector>

How can I programmatically change the ConvertParameter in those TextBlocks and also change the Colorizer ExtendedPropertyName? I can't seem to figure out how to get to them.

Hi,

If a user double clicks on any element in the RadGridView the RowActivated event fires... This is especially annoying as you double click the text box in the filter options to select all text in the textbox (standard windows things) but this triggers the event.

Thanks,

Is it possible to have a multiple column GridViewComboBoxColumn where the dropdown shows multiple columns - almost like another grid?

I've got a dropdown that concatenates 3 data points and it would be cool if the dropdown rendered a mini-grid of values instead of a list of concatenated string values.  Even cooler would be sorting and filtering within the min-grid...

I'm trying to get a handle to the Grouping Event but I'm not having any luck.
Please Help.
