Hello! Could you please help me to fix the following issue when I call _radCombobox.ToggleDropDown():

The control was found, was expanded and then this exception was thrown:

Message: 
    System.TimeoutException : Wait for condition has timed out
  Stack Trace: 
    Server stack trace: 
    WaitSync.CheckResult(WaitSync wait, String extraExceptionInfo, Object target)
    WaitSync.For[T](Predicate`1 predicate, T target, Boolean invertCondition, Int32 timeout, WaitResultType errorResultType)
    WaitSync.For[T](Predicate`1 predicate, T target, Boolean invertCondition, Int32 timeout)
    VisualWait.ForVisible(Int32 timeout)
    VisualWait.ForNoMotion(Int32 initialWait, Int32 motionCheckInterval, Int32 timeout)
    RadComboBox.WaitDropDownAnimation(Int32 millis)
    RadComboBox.ToggleDropDown()

Here is the combobox (as a part of UserControl):

<telerik:RadComboBox  x:Name="CmbAddressType" Grid.Row="1" Grid.Column="3" Grid.ColumnSpan="3">
          <TextBlock>LG Nexus 5X</TextBlock>
          <TextBlock>Huawai Nexus 6P</TextBlock>
          <TextBlock>iPhone 6S</TextBlock>
          <TextBlock>iPhone 6S Plus</TextBlock>
          <TextBlock>Microsoft Lumia 950</TextBlock>
        </telerik:RadComboBox>

Application: WPF

Testing Framework: Progress Telerik Test Studio 2021.3(213.11.3.0)

   I'm attempting to following the instructions at https://docs.telerik.com/devtools/wpf/controls/radrichtextbox/mef to improve the loading time of the RadRichTextBox control.  However the given example is in c#.  I've tried to convert that over to vb.net but I can't seem to find the right assemblies.  

For example:

RadCompositionInitializer.Catalog = new TypeCatalog( 
// format providers 
typeof(XamlFormatProvider), 
typeof(RtfFormatProvider), 
typeof(DocxFormatProvider));
trying:
Imports Telerik
Imports Telerik.Windows.Documents.UI.Extensibility
 
  Dim oTest as RadCompositionInitializer.Catalog = new TypeCatalog( 
typeof(XamlFormatProvider), 
typeof(RtfFormatProvider), 
typeof(DocxFormatProvider))
 
   RadCompositionInitializer seems to come from Telerik.Windows.Documents.UI.Extensibility, but RadCompsitionInitializer.Catalog is unknown and TypeCatalog is unknown.  Anyone have success in implementing this in vb.net?  Many thanks!

I have a linear chart that contains data from 1/4/2019 to 31/3/2020. However, the last tick is not displayed? How to always display the last tick with the corresponding label. Thanks

Hi,

            So, I have been tasked with fixing a XAML issue in RadGridView where FilterMemberPath has been set in the CustomGridViewDataColumn…This creates Custom Filter Options....

            However, the Column Header isn’t highlighting as expected when the Filter is applied…

            Is there a solution to this issue…

Hello.

Same gridview exists in RowDetails in GridView.

I want to hide columns at the same time.
I applied the hide/show column function in the parent gridview right from the sdk example.

However, it is difficult to apply in row details.

I tested it in a slightly different way, but it didn't work.

How should I approach it?
Width column synchronization was also applied to make visible similarly, but it failed.

Thanks.

Hi,

Is there a way I can insert text in Hebrew and scan it?

Because by default I see that it only supports English.

Thanks.

We have requirements to render html contents in List control (ItemsControl).  Collection source may contains upto 200 html content.

Initially we tested RadRichtextbox with HTMLFormatProvider to bind Html content. radrichtextbox along with HtmlFormatProvider works fine for small collection, but if ItemsSource has more than 100 items, we are facing performance issue. 

Therefore I replaced Telerik control with HtmlRenderer.WPF (HtmlPanel) control, which is faster compared to telerik control. HtmlPanel has flow direction issue with arabic text.

Is there any light weight telerik control that can be used to render html contents only.

Hello.

I made a detail row (group) in two grid views.

Both gridview data use the same data and have different outputs.
Here, i want both gridviews to expand equally in the same row when toggled.

(Otherwise, the data can be ignored. I want extended sync on the same data.)

I tried several searches such as RowDetailsVisibilityChanged, toggle style, toggle custom enable behavior, but nothing worked.

Attach the basic data. please help.
Thank you.
