Items.Count always return 0

Hi,

I'm using a RadGridView in my WPF projet and when I load my form, I assign the ItemsSource property of my RadGridView to an object representing an array of values. After that, I'm trying to display a label with the number of items in my grid but the RadGridView.Items.Count method always return 0.

Here is what I'm doing:

RadGridView.ItemsSource; = itemsGrid //Actually, itemsGrid contain 11 elements
GroupBox.Header = RadGridView.Items.Count.ToString(); //Always return 0.

But I can see the 11 elements in my grid!!!
Can you explain this???

Thank's

SplineSeriesStyle resource could not be resolved.

Hello. In View that is inside Prism Module in MVVM multimodule Prism application I have the following XAML line:

<Style TargetType="telerik:SplineSeries" BasedOn="{StaticResource SplineSeriesStyle}">

SplineSeriesStyle resource could not be resolved. Herewith "BasedOn="{StaticResource SplineSeriesStyle}" substring is underlined by a blue wavy line. When I move the mouse cursor to this underlined substring then "SplineSeriesStyle resource could not be resolved" error message is displayed. I use Prism UserControl as the View where abovementioned XAML is placed. Below is XAML of the View with some reductions:

The Shell in my application is standart WPF window (!!! not telerik:RadWindow !!!). This is dictated by the requirements of the technical assignment for the application. There are no Telerik references in Shell project in the solution. But the Prism Module (where abovementioned XAML is located) has the following Telerik references: Telerik.Windows.Controls, Telerik.Windows.Controls.Chart, Telerik.Windows.Controls.Navigation and Telerik.Windows.Data. The version of all these DLLs is 2017.1.117.40. In the solution, Shell project is in different folder then Prism Module projects are. Why SplineSeriesStyle resource could not be resolved? Please help.

BUG: Scroll issues with grouping in Office 2013 theme

When adding grouping, I am experience some strange jumping behavior when the mouse is moved around the scrollview area. Also random amounts of white space are added to the bottom part of the scrollview area.

Changing theme to another will resolve the issue, although I have not tested all themes for complete per theme repro. If you can provide me means to send you a repro project, I have one ready.

Regards,
Maurice

PivotGrid Export does not include DataTemplate

Hi,

We are exporting a to a number of formats depending on what the user selects (using PdfFormatProvider, HtmlFormatProvider etc), and we use a CellTemplateSelector to add a simple image to some columns to indicate an increase or decrease in the value.

When the grid is exported the result show this or anything else in the DataTemplate. Even if we add a simple into the DataTemplate it is still missing from the exported report in any format. The rest of the data is displayed in the exported report normally.

I can understand maybe a binary image not being displayed, but surely the should be.

Are we missing something simple?

Many thanks,

PivotGrid

How to differentiate the OnCreateAutomationPeer??

In RadGrid, you have provided the support for both the screen reader and coded Ui at the same time. Now i have the logic of how you differentiate that the OnCreateAutomationPeer is created for System screen reader(Windows 10 ) or any inbuild screen reader (Narrator or magnifier) else any of the third party tool(like Inspect tool)

Enable/disable SettingsPane on a per shape basis

Hi,

I have added the following to my diagram in order to display the settings pane on my shapes:

<primitives:ItemInformationAdorner.AdditionalContent>

<telerik:SettingsPane Diagram="{Binding ElementName=radDiagram}" />

</primitives:ItemInformationAdorner.AdditionalContent>

Now I am trying to figure out a way to enable / disable the settings pane on a per shape basis. For example, I want to be able to edit settings of square shapes but not circles. Is this something I can do with the item information adorner?

Rgds,

RadMasketTextInput deletes first character

Hi there!

I just found an issue with RadMaskedTextInput that is present in the newest WPF Demos, too. In my scenario, I tried it with no mask. Simply type some word into the control, select all with CTRL+A, then hit a letter on the keyboard followed by a space. If you fast enough (but you should not be so fast, just something like experienced-typewriter-fast) your letter will be overwritten by the whitespace that followed it.

If you can't reproduce the issue, I can post a video about it.

Best Regards
