Hey guys,

I have a RadGridView in the UI of my application and bind it to a VirtualQueryableCollectionView shown in the example:
https://docs.telerik.com/devtools/wpf/consuming-data/using-data-virtualization
That works fine so far.

Since I have a client/server architecture, it may happen that the server updates the database table collection is "looking" on.

Let's say there are 41 entries in the table after the UI started. Then the server adds one entry to the database. Afterwards the server notifies the client and the client executes "view.Refresh();".

Due to sorting the new entry may appear in the UI BUT the VirtualItemsCount remains 41.

I cannot find any method that allows me to refresh/update the underlying collection so that the collection is synchronized to the database.

Is it possible to achive this behavior or do I have to recreate the VirtualQueryableCollectionView with "view = new VirtualQueryableCollectionView (query);" on each refresh?

 

I appreciate any feedback :)

Is it possible to set the Positions property using a style?

Here's mine:

 

Doesn't seem to work. The NumericIndicator is aligned ok (I can see the rectangle positioned correctly in VS designer) but there are no visible NumberPosition objects.

Properties window shows that the Positions property value is an empty collection, and the little rectangle (after the "..." button) is gray. I.e., not indicating that the Positions property is bound to anything.

Hi,

I am using radgridview in my wpf application.When I drag and drop a column to the group panel, the sorting of groups is not done numerically as it is a string field.

I want the grouped data to be sorted numerically.

Any help would be really appreciated.

Hello, I'm trying to style the Row Details, and I'm following the instructions on the help here: http://www.telerik.com/help/wpf/gridview-styling-row-details.html
I'm not seeing the properties shown in the help file. I should see ControlOuterBorder, ControlInnerBorder, etc.. according to the help. I'm using Blend for VS 2013 Do you have a video, or a sample project that does this? Any help will be greatly appreciated .
Thanks,
Scott

Here's the XAML I get.
<Style x:Key="RowDetailsStyleCustom" TargetType="{x:Type telerik:DetailsPresenter}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type telerik:DetailsPresenter}">
<Border x:Name="DetailsBorder" BorderBrush="#FF848484" BorderThickness="0,1">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="DetailsStates">
<VisualState x:Name="DetailsVisible">
<Storyboard>
<ObjectAnimationUsingKeyFrames BeginTime="0" Storyboard.TargetProperty="Visibility" Storyboard.TargetName="DetailsBorder">
<DiscreteObjectKeyFrame KeyTime="0">

<Visibility>Visible</Visibility>
</DiscreteObjectKeyFrame.Value>
</DiscreteObjectKeyFrame>
</ObjectAnimationUsingKeyFrames>
</Storyboard>
</VisualState>
<VisualState x:Name="DetailsCollapsed"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">

</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="Visibility" Value="Collapsed"/>
<Setter Property="IsTabStop" Value="False"/>
<Setter Property="Background">
<Setter.Value>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="#FFC2C2C2"/>
<GradientStop Color="#FFF0F0F0" Offset="0.3"/>
</LinearGradientBrush>
</Setter.Value>
</Setter>
<Setter Property="BorderBrush" Value="White"/>
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="Padding" Value="0"/>
<Setter Property="HorizontalContentAlignment" Value="Stretch"/>
<Setter Property="SnapsToDevicePixels" Value="True"/>
</Style>
</Window.Resources>

After some digging I still am not able to get this to work.
In short, I would like to use the Telerik Components with my own Dictionary.xaml.
Can someone please point me in the right direction or describe what needs to be done.

 

You time in this is much appreciated.

It would be a nicer UX if a user did not have to first move the frozen column indicator in order to resize a column.

I am happy to style it myself this way but I am struggling to find the correct element, is it the PART_FrozenColumnsPreview element?

Hello, my case is: I have a RadContextMenu, and there's a RadListBox filling the RadMenuGroupItem of the RadContextMenu.  And then I added a TextBlock in the ItemTemplate of the RadListBox. And finally, I added a ContextMenu on this TextBlock, this ContextMenu on TextBlock didn't work. Right clicking on the TextBlock which is also the an Item of the RadListBox, no ContextMenu pop up, nothing happened.  So what's the reason of it?  Is this kind of case supported?  Thanks for any comments, that would be great help for me, thanks a lot. 

Hi, I'm trying to use the PDF Viewer control, everything works nicely except for one thing,

he toolbar theme won't change no matter what I select.

 

            <telerik:RadPdfViewerToolBar x:Name="pdfViewTools"
                                         RadPdfViewer="{Binding ElementName=pdfViewer, Mode=OneTime}"

                                         HasPageDownButton="False"
                                         HasPagesCountGroup="False"
                                         HasPageUpButton="False"
                                         HasSignatureButton="False"/>
            <telerik:RadPdfViewer x:Name="pdfViewer"
                                  DataContext="{Binding CommandDescriptors, ElementName=pdfViewer}"
                                  Grid.Row="1"
                                  telerik:StyleManager.Theme="Fluent"
                                  telerik:RadPdfViewerAttachedComponents.RegisterContextMenu="True"/>

 

Where am I going wrong?

Hello,

I'm working on a scenario where i have to use 2 different types of appointments, with different properties. both share a common abstract base class, which is derived from the Appointment Class.

 

When using a ListBox, i would simply put multiple datatemplates with DataType={x:Type ...} into the listbox resources. As this did not work, I tried to override  ScheduleViewDataTemplateSelector:

 

 

this seems to work partially, but I found some problems:

-> the bindings are not recognized, as I cannot set the DataType to DerivedType or to OtherType 
-> Sometimes when switching to other weeks in the scheduleview, I get Binding Errors, because of a missing MyBool Property on DerivedType, and vice-versa

Is there an easier way to get different looks based on the type of the appointment? Could you point me in the right direction, or maybe provide a small sample?

Thanks a lot!

                         

 

 

Hi, 

we are using the rad docking and set a automationid to all levels (RadDocking, RadSplitContainer, RadPaneGroup and RadPane) but if we let the CUIT run it needs much time or he doesn´t find the control.

Also if we check the UI with AccChecker we can see that there is no AutomationId set. 

If have downloaded a example from this thread:

https://www.telerik.com/forums/cuit-is-failing-perform-actions-on-the-controls-placed-inside-the-radpanegroup#g4MK_X_CbU-XMfaGOlK9vg

But it doesn´t work on my computer and I can see that there is no automationid set. 

See AutomationIds in the Code.jpg file.

In the file ACC.jpg you could see that there is no AutomationId found. 

Currently it´s not possible to upload the source code because it´s to big and it´s not allowed.

Could you tell me where we miss something or is it a bug?

Thanks for your help.
