Can't get Heirarchal data to show up

Hi,

I have a situation where I have successfully shown data in a ParentGrid, but now I have setup a child grid but cant get it to display data.

XAML:

<telerik:RadGridView Name="CustomersGrid" ShowInsertRow="True" Grid.Column="0" SelectionChanged="CustomersGrid_SelectionChanged">
            <telerik:RadGridView.ChildTableDefinitions>
                <telerik:GridViewTableDefinition/>
            </telerik:RadGridView.ChildTableDefinitions>
            <telerik:RadGridView.HierarchyChildTemplate>
                <DataTemplate>
                    <telerik:RadGridView Name="ChildGrid" ShowInsertRow="True" Loaded="ChildGrid_Loaded" />
                </DataTemplate>
            </telerik:RadGridView.HierarchyChildTemplate>
        </telerik:RadGridView>

C#:

public MainWindow()
        {
            InitializeComponent();
            var customers = Repo.GetCustomers();
            CustomersGrid.RowIsExpandedChanging += CustomersGrid_RowIsExpandedChanging;
            CustomersGrid.ItemsSource = customers;

            DataContext = this;
        }

This works fine and shows the child grid when clicking on the + sign. The ParentGrid is bound to Customers (Select * FROM Customers) I need to know how to bind the child grids to Agreements (Select * From Agreements where CUST_NO = '" + CUST_NO + "'"). I cant seem to access the Child Grid's itemsource to set the data binding.

What am I doing wrong?

Thank you very much!
Ron

Get Item from current point

Hi,

I like to get the current item in a drag & drop operation.
It´s shared code from silverlight and there it´s possible to get the current item with the following code:

private System.Windows.Controls.ListBoxItem GetItemFromPoint(FrameworkElement listBox, Point CurrentPoint)

{

var p = listBox.TransformToVisual(App.Center.RootVisual).Transform(CurrentPoint);

IEnumerable hits = VisualTreeHelper.FindElementsInHostCoordinates(p, listBox);

System.Windows.Controls.ListBoxItem item = null;

foreach (UIElement element in hits)

{

if (element is System.Windows.Controls.ListBoxItem)

{

item = (System.Windows.Controls.ListBoxItem)element;

break;

}

return item;

}

But now I´m using WPF and the RadListBox. The return type now is a RadListBoxItem and the parameter listBox is a RadListBox control.

Which opportunities do I have with the RadListBox in WPF?

Thanks

<globalization:NumberFormatInfo NumberGroupSeparator="" NumberDecimalSeparator="." />

</telerik:RadNumericUpDown.NumberFormatInfo>

NumericUpDown control allows to enter commas (the screenshot is attached). How can I forbid that?

Removing Style and Text sections from the Settings Pane

Hi There,

I plan on overriding the Settings Pane by removing the Style and Text sections and then added 1 or 2 additional ones in their place. I'd like to maintain the functionality exposed in Home and Size however, just maybe re-arrange them (so my 2 custom ones are first followed by Home and Size). I can't seem to find a way to simply override the Settings Pane without creating a completely new Settings Pane (like in the MindMap example), can you help point me to an example of this or provide a suggestion on accomplishing this?

Thanks!
Tim

Q2 2013 upgrade regression: resource load failure for "themes/office/black/gauge.xaml"

I did upgrade to Q2 2013 yesterday and my solution regressed, wondering if anyone out there seen this or know about this and help me figure out a way out of this.

I am seeing resource load failure for "themes/office/black/gauge.xaml" in both designer and runtime, build passes though.

I did upgrade control suite to Q2 2013, no other changes.

I noticed that the gauge.xaml was embedded in the assembly "Telerik.WIndows.Controls.DataVisualization.dll" before (in Q2) and it is no longer there now. I could not find any related information in readme, anyone knows how to find this missing resource? Thanks in advance for any tips or links.

Bug in placing Axis line.

We are using HorizontalBarSeriesDefinition for our application. When we open this application for first time axis line is placed at correct location but when after playing for certain time when we display this chart again, Axis line is misplaced from its actual position. In our code we have assigned only style to specify color and FontWeight to axis line. Apart from that there is no code for axis line.

Can you please let us know is there any way to redraw axis line at its correct location.

Scatter Point Relative Size?

I need to create a scatter plot that looks something like the image I've attached which features a combination of scatter points and rings of defined sizes.

I have been able to use the ScatterPointSeries.PointTemplate to create the rings by modifying the width, height, stroke and fill properties so that I get a hollow ring that is larger than the scatter points. However I need to be able to control the size of the ring relative to the chart axis.

It appears that something similar to what I need was available in BubbleChart (BubbleSizeRelative) but this is not available in ChartView yet.

Is there any way I can do this with the current version and if not do you know when it will be implemented?

Thanks for the help,

Andy.
