Hi there,

I did add the RadWindow class to my project and I found an exception occuring somehow in a random fashion.

There are serveral RadWindows in my application and they do work fine. But when I do add the ShowDialog of one of the RadWindows to the SelectionChanged event of a RadTreeView on my form, I do receive the exception shown below when closing the window again. This exception does not always show up, it only occures in a somehow random way. As you can see, there seems to be a problem in the OnThumbDragStarted event handler or one of the methods it is using.

I'm using the Q1 2011 version of the telerik libraries as I did update the version when I was working on this issue, but the update did not solve the problem.

Do you guys have an idea why I do receive this exception?

VirtualQueryableCollectionView custum grouping

I have my custom VirtualQueryableCollectionView to connect to my database.
I can read data an sorting. Now i would like to do grouping. When i drag and drop column to group panel to group by this column it creates one group expander with null value. When i expand this expander there is all my grid row.
Can you help me how can i create my custom grouping?

Thanks Josef.

public class VirtualQuery : VirtualQueryableCollectionView

{

WPF.Models.VirtualQuery _cacheVirtualQuery;

CacheConnection _conn;

public VirtualQuery(WPF.Models.VirtualQuery cacheVirtualQuery)

{

LoadSize = 1000;

_cacheVirtualQuery = cacheVirtualQuery;

_conn = cacheVirtualQuery.Connection;

_cacheVirtualQuery.CreateQuery();

VirtualItemCount = Convert.ToInt16(_cacheVirtualQuery.VirtualItemCount);

ItemsLoading += VirtualQuery_ItemsLoading;

}

private void VirtualQuery_ItemsLoading(object sender, VirtualQueryableCollectionViewItemsLoadingEventArgs e)

{

SetUpCacheQuery();

_cacheVirtualQuery.ItemsLoading(e.StartIndex, e.ItemCount);

VirtualItemCount = Convert.ToInt16(_cacheVirtualQuery.VirtualItemCount);

#region smazat dynamicky objekt pomale

/*CacheDynamicObject[] DataContext = new CacheDynamicObject[_cacheVirtualQuery.QueryItems.Count] ;

for (int i = 0; i < _cacheVirtualQuery.QueryItems.Count; i++)

{

DataContext[i] = new CacheDynamicObject(_cacheVirtualQuery.QueryItems[i] as CacheArrayOfDataTypes);

}*/

#endregion

object[] DataContext1 = new object[_cacheVirtualQuery.QueryItems.Count];

for (int i = 0; i < _cacheVirtualQuery.QueryItems.Count; i++)

{

DataContext1[i] = new Dictionary<string, string>(_cacheVirtualQuery.QueryItems[i] as CacheArrayOfDataTypes); ;

}

Load(e.StartIndex, DataContext1);

_cacheVirtualQuery.QueryItems.Clear();

_cacheVirtualQuery.Connection.ForceSync();

}

private void SetUpCacheQuery()

{

_cacheVirtualQuery.SortDescriptors.Clear();

foreach (Telerik.Windows.Controls.GridView.ColumnSortDescriptor item in SortDescriptors)

{

WPF.Models.SortDescriptor desc = new WPF.Models.SortDescriptor(_conn);

desc.SortUniqueName = item.Column.UniqueName;

desc.SortDirection = item.SortDirection.ToString();

_cacheVirtualQuery.SortDescriptors.Add(desc);

}

grouping?

RadDocking with ActiveX UserControl

Hi,

I have an issue with the WPF RadDocking Control (Version Q3 2010).

I implement the RadDocking on my Window, some RadPane contains Usercontrol.

Here's the XAML :

<telerikDocking:RadSplitContainer InitialPosition="DockedLeft" Orientation="Vertical">

<telerikDocking:RadPaneGroup>

<telerikDocking:RadPane Header="Overview" CanUserClose="False" >

<my:OverviewControl Margin="5 5 5 5" x:Name="ucPlanSituation"/>

</telerikDocking:RadPane>

</telerikDocking:RadPaneGroup>

<telerikDocking:RadPaneGroup>

<telerikDocking:RadPane Header="Légende" CanUserClose="False" >

<my:TocControl Margin="5 5 5 5" x:Name="ucLegende"/>

</telerikDocking:RadPane>

</telerikDocking:RadPaneGroup>

</telerikDocking:RadSplitContainer>

My two usercontrols (TocControl and OverviewControl) have some ActiveX controls nested inside. When the pane is docked it displays perfectly but as soon as I pin or make it floating it doesn't display anymore.

Do you know a workaround to fix this issue ?

Thank you and I wish you a great day.

Problem with changing CategoryBrush value on the fly

Hello,

I have a class “Priority” which derives from the Category class and fires PropertyChanged when (New) CategoryBrush changes.

I assign the collection of Priority objects to the CategoriesSource property of the ScheduleView control.

The Edit window loads the list fine, but when the brush color of the Category aka Priority changes in the configuration window - the Edit window doesn’t reflect the change. Other controls bound to the CategoryBrush property of the same collection change the color but not the ScheduleView.

Can you see why?

Thank you.

Linear chart in circle

Hi,
I have just started my adventure with WPF. I have heard that it is dedicated for graphical applications. I'm interested in creating a control that handles linear chart and transform it into chart in a circle. I just wonder if there is some easy way to do that?

Thank you in advance for any reply.

input behavior

I was excited to get a new masking control, but this soon turned to disappointment. Our users have difficulty with these controls as they are not intuitive. They expect it to behave the same as if you were entering something into an Excel spreadsheet cell and I don't blame them. It's confusing to me as well. I've tried all kinds of variations of textmode, autofill properties, and InputBehavior to get a mask n5.2 to behave properly. Essentially I think it should behave just as a regular textbox while entering data and display according to the mask when viewing the data.

MaskedInput (Numeric, DateTime, Text, Currency)

Upgrade Toolbox failed

Hi,

I'm trying to upgrade my Toolbox to the latest release (2011 Q1 SP1 - 2011.1.419.35) but I keep getting the following error:

Telerik VSExtensions: UpgradeToolbox: Access to registry key 'HKEY_LOCAL_MACHINE\Software\Microsoft\VisualStudio\9.0\Packages\{2c298b35-07da-45f1-96a3-be55d91c8d7a}\Toolbox' is denied. (Toolbox upgrade failed)

I installed the update via the update tool and all worked fine. Then I accidently selected to roll back the Toolbox to the previous version. Now I can't get the latest toolbox to show.

I'm using VS2008. Does anyone know how I can clear the toolbox and get the newer version to show up again? I've tried re-installing the latest release MSI but it hasn't done the trick.

Thank you for your time,

Rob
