Hi,

I have a problem using the

GridViewCheckBoxColumn
GridViewComboBoxColumn

When I edit data in a "GridViewDataColumn" and execute my custom "UpdateItemCommand" I have no problems and my SelectedItem displays the changes which were entered in the "GridViewDataColumn".
However the problem occurs when I edit a "GridViewCheckBoxColumn" or "GridViewComboBoxColumn". The SelectedItem does not display the changes made by these Columns.

Thank you for your help!
Martin

MouseLeftButtonDown-Event don't works

Hello friends,

I am trying to implement the MouseLeftButtonDown-Event for some PanelBarItems. But the Event isn't fired. Could you please help me to find out why it isn't?

<telerik:RadPanelBar ExpandMode="Multiple" VerticalAlignment="Stretch" Name="pbarMain">

<telerik:RadPanelBarItem VerticalAlignment="Stretch" IsExpanded="True">

<telerik:RadPanelBarItem.Header>

<StackPanel Orientation="Horizontal" Margin="5 4 5 5">

<Image Source="Images/kapazität.ico"

Style="{StaticResource style_image_20x20}"/>

<Label Content="Kapazitäten" FontWeight="Bold"/>

</StackPanel>

</telerik:RadPanelBarItem.Header>

<telerik:RadPanelBarItem MouseLeftButtonDown="RadPanelBarItem_MouseDown"

Is Expand property Not Working in RadTreeListView

Hi,
Previously I was using this code in WPF .net 4.0 framework and was working correctly.

Code at RowLoaded Event:

TreeListViewRow row = e.Row as TreeListViewRow;

Binding binding = new Binding("IsExpanded") { Source = row.Item };

binding.Mode = BindingMode.TwoWay;

row.SetBinding(TreeListViewRow.IsExpandedProperty, binding);

which indirectly calls the

RowIsExpandedChanging event somehow.
But now when I migrated to .net 3.5 framework, due to some limitations, the same code was not working.
Now it is not calling the RowIsExpandedChanging event.
Please suggest me how to overcome from this problem, is there any other way to do the same in .net 3.5.

Thanks in Advance.

StackedBar Legend item not showing.

Hi, I have a problem when populating stacked bar charts. My code is following:
XMAL:

<telerik:RadChart x:Name="chart" PaletteBrushesRepeat="False" telerik:Theming.Theme="Summer">

</telerik:RadChart>

C#:

chart.SeriesMappings.Clear();

chart.DefaultView.ChartArea.DataSeries.Clear();

chart.DefaultView.ChartLegend.UseAutoGeneratedItems = true;

chart.DefaultSeriesDefinition.LegendDisplayMode = LegendDisplayMode.SeriesLabel;

for (int i = 0; i < model.Captions.Count; i++ )

{

SeriesMapping sm = new SeriesMapping();

StackedBarSeriesDefinition dd = new StackedBarSeriesDefinition();

dd.StackGroupName = "Stack1";

sm.SeriesDefinition = dd;

sm.LegendLabel = "Stacked Bar " + i;

sm.CollectionIndex = i;

ItemMapping im1 = new ItemMapping();

im1.DataPointMember = DataPointMember.YValue;

sm.ItemMappings.Add(im1);

chart.SeriesMappings.Add(sm);

}

List<double[]> itemsSource = new List<double[]>();

for (int i = 0; i < model.Children.Count; i++)

{

double[] d = model.Children[i].Values.Select(s => s.AdjustedValue).ToArray();

itemsSource.Add(d);

}

I'm not sure where I'm going wrong here but I'd thought "sm.LegendLabel = "Stacked Bar " + i; " would provide my with legend items.

Best regards
Kristján.

GridView Group Dragging in the menu

Hi There

I have a menu which contains a gridview, I cant seem to drag column headers to the group header though when in that menu. The menu just dissappears. Code for the grid below:

AutoGenerateColumns="False"

ItemsSource="{Binding FullAssetList}">

<!--<telerikGridView:RadGridView.GroupDescriptors>

<telerikData:GroupDescriptor Member="SiteName" />

</telerikGridView:RadGridView.GroupDescriptors>-->

<telerikGridView:RadGridView.SortDescriptors>

<telerikData:SortDescriptor Member="SiteId" SortDirection="Ascending" />

<telerikData:SortDescriptor Member="OrderByProcessType" SortDirection="Ascending" />

QualitativeRange Error on Binding

Hello,

in my scenario i try to visualize the variance of a production cyle within a radgridview. For this i want to show a warning/error range.

<telerik:RadHorizontalBulletGraph Width="150" Height="20"

QuantitativeScaleVisibility="Collapsed"

FlowDirection="LeftToRight"

FeaturedMeasure="{Binding Input0TimeLast}"

ComparativeMeasure="{Binding Auftrag.ZyklusIstSoll}">

<telerik:RadHorizontalBulletGraph.QualitativeRanges>

<telerik:QualitativeRange Brush="Red" Value="{Binding ZyklusErrorBound}" />

<telerik:QualitativeRange Brush="Yellow" Value="{Binding ZyklusWarningBound}" />

<telerik:QualitativeRange Brush="Green" Value="{Binding ZyklusOkBound" />

</telerik:RadHorizontalBulletGraph.QualitativeRanges>

</telerik:RadHorizontalBulletGraph>

public int ZyklusErrorBound

{

get

{

var x = this.Auftrag.ZyklusIstSoll - this.Auftrag.ZyklusIstToleranz;

return x;

}

public int ZyklusWarningBound

{

get

{

var x = this.Auftrag.ZyklusIstSoll - (this.Auftrag.ZyklusIstToleranz / 2);

return x;

}

When i bind the three QualitativeRange`s i get a exception "Sequence contains no elements". If i set instead of ZyklusOkBound a fixed value for example, no exceptions is thrown. But the two other values are not called from my Itemssource (i´ve checked that by setting a breakpoint on my getters). Instead of a message shows up in my console:

System.Windows.Data Error: 2

:
Cannot find govening FrameworkElement or FrameworkContentElement for
target element. BindingExpression:Path=ZyklusWarningBound;
DataItem=null; target element is

'QualitativeRange' (HashCode=7579691); target property is 'Value' (type 'Double')

System.Windows.Data Error: 2

: Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=ZyklusErrorBound; DataItem=null; target element is

'QualitativeRange' (HashCode=7579691); target property is 'Value' (type 'Double')

What is absolutely remarkable, if i bind ZyklusErrorBound or ZyklusWarningBound to FeaturedMeasure the value is retrieved..

Thanks in advance for your help.

Map freezes

Hi,
I'm testing RadMap. I build a window with a radmap and a listbox with locations (based on your samples).
After a few changes in the listbox, the window freezes. I must then stop the process from visual studio.
Bassically, i had a code like this:

private void listBox_SelectionChanged(object sender, SelectionChangedEventArgs e)

{

ListBox lista = sender as ListBox;

if (lista.SelectedItem == null) return;

destino = (Location)lista.SelectedItem;

this.radMap1.Center = destino;

}

I tried in debug and in release modes.
I tried with both providers, bing and open.
If I use a 'zoom effect' like in your samples (changing the last line to "ZoomOut();") the freezes occurs after 5-10 changes in the listbox. If I use the showed code, the freezes occurs after 10-50 changes.

Thanks in advance, and excuse me if my english is not good.

ShowsConfirmationWindowOnDelete

we used to have

ShowsConfirmationWindowOnDelete

property in RadScheduler, what is the counterpart of that property in ScheduleView? I noticed that Deleting events gets fired AFTER confirmation dialog is shown, so I cannot override it by e.Cancel=true...

Please advise
