Hi guys,

I have a small testproject where I want do display a few projects with appointments.
I wanted to use the Group functionality together with resourcetypes.

Now everything works but not in the inital loading. Somehow the Group part on the left side is not displayed.
After pressing the button "aktualisieren" it displays as intended.

I tried to call the aktualisieren after loading of the window, but same, it stays empty at first.

I attached the project.
Maybe someone has an idea what causes this.

Greetings.

I am changing TrackBallTemplate and I want to get the following result:

I changed the palette to a custom palette using PaletteEntryCollection SeriesFamily = "Line" and ChartPalette.GlobalEntries

I am using ChartSeriesProvider and style TargetType = "telerik: LineSeries"

But from the DataContext of the TrackBallTemplate, I cannot find the brushes...

StrokeShapeStyle returns not my color: #FF5AA4D4
LegendItem is not available

How do I get the line brushes I need?
Thank you

Hello.

I develop other program modules.

There was a problem using the UI component telerik here.

When executing the main program with each different project, module A and module B are executed.
At this point, the telerik assembly starts loading.

In A, the telerik version is 2021.2.615.45, and B is 2021.3.1025.45. (different versions)
And when I run A and B in the main program, the screen of A is not shown and only B is shown.


That is, my guess is that only the last loaded telerik assembly will be recognized.
Is there any way to solve this?

summary) When loading two versions of telerik in one program, one screen is blank.

Thanks.

Hi, trying to speed up the points-plot (around 1000-5000 points)

I can so far conclude that we can only get a tooltip for XamlRenderOptions DefaultVisualsRenderMode="Separate" otw, no tooltip is visible.

I have tried a few options (see below)  - but maybe the behavior changes once I change the render mode ?

- XamlRenderOptions DefaultVisualsRenderMode="Batch"  -> no tooltip
- (geometrytype not supported by scatterpointseries)
- BitmapRenderOptions -> no tooltip
- Direct2DRenderOptions -> not tooltip

Hello!   I'm using the Telerik ExplorerControl - both as part of the RadOpenFileDialog, and in a custom dialog of my own - and in both cases, I'm seeing a possible bug when browsing to network resources.

I can type a UNC path for a network location for which I have full access in the location bar:



When I hit enter, the ExplorerControl shows the contents at that location, but only for a second or less:



Then, the dialog changes to the root of the location I entered:



If I go to the history drop-down, it looks like this - each time I try to go to the storage subdirectory, it goes back to the root:



Oddly, if I select the location in the history, it does show the contents at that location - so there's not a problem with my permissions to explore that location:



Is there a way to prevent the ExplorerControl from doing this?  The selection always seem to return to the root of the UNC path, within less than a second.  (See the attached .gif). 

I'm using Version 2021.2.615.50 at the moment.  Any help would be most appreciated.

Thanks,

Ed

Hi, I have the following code and I want to have an animation to enable and disable any "radpane "in the related "radpanegroup".

For example, when I put a "radpane" in pin mode, its width increases by 3 seconds, or another example is that the border color changes.
My solution is to use: 

<telerik:RadDocking>

        ...

...

...

<telerik:RadDocking.FlyoutBehavior>
                <local:AnimatedFlyoutBehavior/>
            </telerik:RadDocking.FlyoutBehavior>

</telerik:RadDocking>

I used the IFlyoutBehavior interface and as a result the following functions were implemented:

  void IFlyoutBehavior.OnMouseEnter (IFlyoutHost host, RadPane targetPane)
        {

        }

        void IFlyoutBehavior.OnPaneActivated (IFlyoutHost host, RadPane targetPane)
{
        }

        void IFlyoutBehavior.OnMouseLeave (IFlyoutHost host)
        {

        }

        void IFlyoutBehavior.OnOpeningTimerTimeout (IFlyoutHost host)
        {


        }

        void IFlyoutBehavior.OnClosingTimerTimeout (IFlyoutHost host)
        {

        }

        void IFlyoutBehavior.OnPaneDeactivated (IFlyoutHost host, RadPane targetPane)
        {
            var selectedPane = host.SelectedPane;

            if (selectedPane! = null &&! selectedPane.IsActive && host.CurrentState == FlyoutState.Opened)
            {
                host.StartCloseAnimation ();
            }
        }

        void IFlyoutBehavior.OnPaneMouseLeftButtonDown (IFlyoutHost host, RadPane targetPane)
        {
            if (host.CurrentState! = FlyoutState.Opened)
            {
                host.StartOpenAnimation ();
            }
            else
            {
                host.StartCloseAnimation ();

            }
        }

    }

I could not use enough of this interface. Is there a better way to customize animation in radpane or to develop it that way?

Hi,

I have a RadContextMenu and want to use access keys with it, I've added underscores to headers in my RadMenuItems and functionally it's all working however the characters in the menu aren't underlined, I tried looking into this online but could only seem to find anything on getting them to appear in a RadMenu when using alt which doesn't appear to be an option for the context menu control. It seems like it should be default functionality so I don't know if maybe I'm just missing something obvious.

Thanks for any help

Hello,

I use the SyntaxEditor with the MS Roslyn compiler toolbox.

1) The location of the source of the compiler error (e.g., an unknown identifier) is defined by the first and last character positions of the identifier.

How to convert these positions into line number and character position in the SyntaxEditor?

2)  How to underline (e.g. in wavy red, like in Visual studio) temporarily, the source of the error, in the SyntaxEditor?

Thanks

I am trying to determine how to have the set number value start at the current line that is being highlighted in RadRichTextBox for WPF.

Here is an example, with steps to replicate:

1). Enter the following text(the word So. 6 times)(Do not add any spaces after each period):

2) Now put he 6 words containing So. into a numerical list:

3. Now highlight line number 4, like this(do not click your mouse and enter a space at any time):

4. Right click, and set numbering value to 74:

Final result:

Question, why is the numbering value starting at the next line(#5 in this case),  as opposed to the current line being underlined(#4)?

Is there a way to make the numbering value start at the current line(#4) with one extra space highlighted, with only selecting line #4 with the mouse(not clicking on it at all)? For example, following the exact same above steps but not selecting the extra space at the "." punctuation mark produces the following:

.

What is the reason for this highlighting of an extra space causing the numbering to start on the next line? Is a fix possible so that all characters highlighted on the current line and setting the numbering value will result in the number value changing at the current line, not the line after?

Thank you.

My app will typically work with 6 workbooks instantiated (one window each) simultaneously.
User will work interactively with the worksheets, just like he would if Excel was used.
After some editing, he/she will perform some heavy access of data (mostly reading), processing the data and send the outputs to another application (as xml documents by COM interface)

As a test I instantiate 6 spreadsheets, one window each and load them with the same xlsx file.
The loaded workbook filesize is about 430 kBytes and contains 37 worksheets (no graphs or other graphics, just plain worksheets) with a total of 45520 cells with data and 1489 formulas (according to Excel/Review/Workbook Statistics) .

My testmachine has an i7-8700 cpu (6 cores) and available memory before application start of about 24 GBytes of rwm.

The opening time until all 6 spreadsheets are visible and editable on screen is about 90 seconds and final working set is about 1.4 GBytes(!!).
Using Excel 2021/x64 and opening the same 6 workbook instances (6 different copies to enable single process) takes about 6 seconds with final working set of 237 MBytes.

The cpu load while editing the workbooks seems to be much more demanding than Excel as well, not really measured, probably acceptable.
Accessing cells data (reading plain cell data) seems to be doable with acceptable performance.

The long loading time and the high memory demand is not acceptable and means that I cannot use WPF radSpreadsheet as is and will need advice to lower these numbers if possible.
Alternatives are:
Using Excel (accessing with Excel COM automation), but I would very much like to avoid the license cost (and more complex application
development).

Finding another component supplier, similar to Telerik radSpreadsheet, but with possibly better performance (I guess it is not proper to ask in this forum for advice of which supplier could be recommended :)
