Greetings.

I am using the Telerik RadGridView control to display data. In one screen I am using it without the rowstyleselector, in another I am using it with the rowstyleselector.

In the instance without the rowstyleselector, I use GridLinesVisibility="None"> and it works fine, the gridlines are gone.

But in the instance with the rowstyleselector, I use the following code, but the gridlines are still visible.

<Queue:TelephonyCallQueueRowStyleSelector.ConnectedToOtherStyle>
            <Style TargetType="TelerikGridView:GridViewRow">
                <Setter Property="Background">
                    <Setter.Value>
                        <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
                            <GradientStop Color="Black" Offset="0.96"/>
                            <GradientStop Color="#FFBDFDBD" Offset="0.95"/>
                        </LinearGradientBrush>
                    </Setter.Value>
                </Setter>
                
                <Setter Property="Grid.ShowGridLines" Value="False" />
            </Style>
        </Queue:TelephonyCallQueueRowStyleSelector.ConnectedToOtherStyle>

Why won't the gridlines go away?

Thanks,

We are facing issue while opening a word document in radrichtextbox control using ribbon button UI as well as importing the document using DocxFormatProvider and XamlFormatProvider. The control renders the word file in a very messy format. Common features of MS office are used in the file. Sample file, code and video evidence is attached. Kindly look into this issue. Thank you

Hello.
I am testing a WPF Org Chart Diagram and I need to dynamic create child nodes when user clicks the Node (lazy loading).
But I have a problem. When I create new node and link and call diagram.Layout(...), routing is corrupted.

How to fix it?

I have a RadCartesianChart in that I am adding different series (Area/Line mainly)  and calculating datapoint on mouse hover .

I would like to prioritize to line series and calculate datapoint of Line series  if line series is over lapped with area series.

I can get the selected series if mouse click happened and chartBehavior is associated with RadCartesianChart , but looking for solution which give me current hovered series.

Is there any way in code behind or in event I can get which series of chart is currently hovered ?

appreciate your help

Hi Telerik,

Can you advice me how to handle my issue with ChartTrackBallBehavior. As you can see in attached image, ChartTrackBallBehavior  hides chart itself. I would like to know what is my options to solve this issue?

Is it possible to change position of ChartTrackBallBehavior when it start hiding chart?

My another idea is change vertical range so tracking ball will be always above chart. telerik:LinearAxis has Maximum property. I would like to stay with auto calculated range and just increase it about 20%. Is there some way how to achieve this? This is my current axes definition:

 

<telerik:RadCartesianChart.VerticalAxis>

                        <telerik:LinearAxis MajorStep="100" SmartLabelsMode="SmartStepAndRange" />
</telerik:RadCartesianChart.VerticalAxis>

 

Thanks,

Vaclav

 

Hello,

First thank you for xaml-sdk\Map\WPF\SQLGeospatialData\ example

As i can see telerik:SqlGeospatialDataReader has property PointTemplate, but how i can set template for all other Sql Geospatial Data Types?

The SqlGeospatialDataReader supports the following geometry types:
Point
LineString
Polygon
Triangle
MultiPoint
MultiLineString
MultiPolygon
GeometryCollection

In winform demos, it use FastLineSeries and have nice fps, very smooth.

how can i do it in wpf?

Hi, I'm currently using Radsplitcontainer, radpanegroup and radpane and I'm having a problem with settings which of the tab in the radpanegroup should be active. I got two viewmodels, and I want to use a bool to make the tabs active according to which ViewModel event that is invoking. How can I do this?

Because I'm using a gridView, and by selecting an item in the grid, I the tab to be active depending on which gridview I'm selecting an item on. This mean that I'll have 2 gridviews, and the radpane is supposed to be a tab window that shows the details of the item selected.

<telerik:RadPaneGroup TabStripPlacement="Top" telerik:ProportionalStackPanel.RelativeSize="100,300" >
                        <telerik:RadPane Header="{Binding viewModel1.Title, Mode=TwoWay}" CanUserClose="False" CanDockInDocumentHost="True" >
                            <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
                                <ContentControl Content="{Binding viewModel1}"
    ContentTemplate="{StaticResource ViewEditorTemplate1}" />
                            </ScrollViewer>
                        </telerik:RadPane>
                        <telerik:RadPane Header="{Binding viewModel2.Title}" CanUserClose="False" CanDockInDocumentHost="True" telerik:ProportionalStackPanel.RelativeSize="200, 100" >
                            <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto">
                                <ContentControl Content="{Binding viewModel2}"
                                                ContentTemplate="{StaticResource ViewEditorTemplate1}"/>
                            </ScrollViewer>
                        </telerik:RadPane>
                    </telerik:RadPaneGroup>

The focus events for the RadRichTextBox don't appear to be firing correctly.  There's a number of issues, which I'll list in turn.  We need to do things according to whether the control has the focus or not, and currently its unexpected behaviour is causing us a lot of problems.

For the purpose of reproducing the behaviour, simply place a RadRichTextBox control on a view, and handle its GotFocus and LostFocus events with the following event handlers, which will write to Visual Studio's Output window so you can see that they've been called.

private void RadRichTextBoxEx_LostFocus(object sender, RoutedEventArgs e)
{
    Console.WriteLine("LostFocus");
}
 
private void RadRichTextBoxEx_GotFocus(object sender, RoutedEventArgs e)
{
    Console.WriteLine("GotFocus");
}

#1 - Clicking the mouse anywhere within the control fires the events

Let's say the RadRichTextbox control has the focus.  Clicking the mouse anywhere within the control fires the LostFocus and GotFocus events twice, with the following output in the VS Output window:

LostFocus
GotFocus
LostFocus
GotFocus

I would expect neither the LostFocus not the GotFocus events to be fired, as the control already has the focus.

If the control doesn't have the focus and you click in it (giving it the focus), then the following events are currently raised:

GotFocus
LostFocus
GotFocus

In this situation, I would expect only the first GotFocus event to be raised.

NOTE: I have tried handling the KeyboardGotFocus/KeyboardLostFocus events, and they behave the same way.

#2 - Clicking on a control that doesn't take focus, still fires these events

Let's say the RadRichTextBox control has the focus, and you click on a different control that doesn't steal the focus from the RadRichTextBox control, such as a ribbon button (note, we aren't using the Telerik ribbon currently, but that shouldn't matter).  Doing so fires the events like so:

LostFocus
GotFocus

The expected behaviour is that neither of those events should be called.

#3 - When overriding the RadRichTextBox control, neither the OnGotFocus, nor the OnLostFocus methods fire

While this is not really an issue for me, I tried overriding the RadRichTextBox control to add my own behaviour to it, and found that if I override the OnGotFocus and OnLostFocus methods, they never get called.  Something maybe to look at as part of this problem.

Please note that all these scenarios have been tried on a plan TextBox control, and it fires its GotFocus/LostFocus events as per my expected behaviour described.  Therefore, I would expect the RadRichTextBox control to behave in the same manner.

Thanks

Hello,

In our application we are using a few separator that are used to resize the two panels (right & left), those two panels contain GridViews. It used to work perfectly but when switching to .NET 4.7.2 (from 4.5.2), this resizing causes the app to freeze entirely. Removing the GridView controls seems to fix the issue, hence why I think there is something wrong with the GridView (or one of the Windows API its using)

Now, the issue only seems to happen on a specific hardware and some kind of setup. An easy way to reproduce it is (in our case) to run the app on the main screen on a Lenovo E580 laptop. We are currently running WPF 2018 R2, but upgrading to R3 doesn't fix the issue.

I was simply wondering, before I open a bug and build a test app to show the error, if you were aware of an issue with the GridView (or other Telerik control for that matter) when running .NET 4.7.2?

 

Best Regards,

Bastian
