When I use the WindowsFormsHost in Radbusyindicator,

then I change the window size, and the UI shows very slowly and seems wrong.

The content of the WindowsFormsHost is just a Label.

I am not sure if there are some details in this case.

<telerik:RadBusyIndicator IsBusy="False">
        <Grid>
            <Grid.RowDefinitions>
                <RowDefinition Height="*"/>
                <RowDefinition Height="30"/>
            </Grid.RowDefinitions>
            <WindowsFormsHost>
                <cc:UserControl1/>
            </WindowsFormsHost>
        </Grid>
    </telerik:RadBusyIndicator>

Hello! I have a RadGanttView with custom columns (which can be switched on and off on fly). The problem is that after any interaction with this control GridView part shows horizontal scroll bar, but splitter doesn't go right although there is more than enough space to resize (Picture 1).

It doesn't really matter how many columns are there - GridView resizes itself to be a bit smaller than enough to fit all the columns and doesn't expand anymore (Picture 2), leaving at least 0.5 cm of free space on the right (on 17" FullHD display) (Picture 3).

At the same time there is no problem with shrinking, it's possible to move splitter to the left until GridVIew part becomes completely invisible.

Thanks, Dmitrii

UPD: I've checked variables in Dynamic Visual Tree and found that ExtentWidth of TreeRenderingPanel element is always 3 units more than needed. Is there a way to fix this?

not sure why the size of the combobox arrow is that small , any idea how to change it?

Thanks,

Hello,

I noticed that the RadRichTextBox is not working as expected.

According to the documentation, SHIFT + ENTER should create a new line and ENTER a new paragraph.
For some reason the ENTER key is not working. My final go is to switch between SHIFT + ENTER and ENTER as described in the following link:

https://www.telerik.com/forums/wpf-radrichtextbox---swapping-enter-key-and-shift-enter-keys-behavior

How can I do that? the AcceptReturn is set to True, but the PreviewKeyDown event is not triggered for ENTER.

Hi Team,

In my LineSeries chart I want to change the color of the line dots based on a property of my bound list item.

The ItemSource of my LineSeries is an ObservableCollection<MonthlyTracking> . The MonthlyTracking class looks like this:

   public class MonthlyTracking : INotifyPropertyChanged
    {
        [....]

        private string monthString;
        public string MonthString
        {
            get => this.monthString;
            set
            {
                this.monthString = value;
                this.OnPropertyChanged(nameof(this.MonthString));
            }
        }

        private double actualValue;
        public double ActualValue
        {
            get => this.actualValue;
            set
            {
                this.actualValue = value;
               this.OnPropertyChanged(nameof(this.ActualValue));
            }
        }

        private int statusId;
        public int StatusId
        {
            get => this.statusId;
            set
            {
                this.statusId = value;
                this.OnPropertyChanged(nameof(this.StatusId));
            }
        }

     [....]

    }

My XAML Code looks like this:

<telerik:RadCartesianChart>
     <telerik:RadCartesianChart.HorizontalAxis>
        <telerik:CategoricalAxis ShowLabels="True"/>
     </telerik:RadCartesianChart.HorizontalAxis>
	 
     <telerik:RadCartesianChart.VerticalAxis>
        <telerik:LinearAxis />
    </telerik:RadCartesianChart.VerticalAxis>
                
	<telerik:RadCartesianChart.Series>                   
         <telerik:LineSeries ItemsSource="{Binding MonthlyTrackingList}" CategoryBinding="MonthString" ValueBinding="ActualValue" >
             <telerik:LineSeries.DefaultVisualStyle>
                <Style TargetType="Path">
                    <Setter Property="Width" Value="10" />
                    <Setter Property="Height" Value="10" />     
                    <Style.Triggers>
                        <DataTrigger Binding="{Binding StatusId}" Value="1">
                            <Setter Property="Fill" Value="LimeGreen" />
                        </DataTrigger>
                        <DataTrigger Binding="{Binding StatusId}" Value="2">
                            <Setter Property="Fill" Value="LightCoral" />
                        </DataTrigger>
                    </Style.Triggers>
                </Style>
            </telerik:LineSeries.DefaultVisualStyle>
         </telerik:LineSeries>
    </telerik:RadCartesianChart.Series>
	
</telerik:RadCartesianChart>

The line is drawn in the chart. Unfortunately my binding in telerik:LineSeries.DefaultVisualStyle is wrong. The property StatusId is not found. Can you help me?

Kind regards,

Mario

Hi I have two RadGridView , first one consists of basic controls it works well.

However, the other thing is that the page is created, but the controls are not displayed at all.

the only difference is that the second radgridview using CellTemplate.

<telerik:GridViewDataColumn  HeaderCellStyle="{StaticResource CustomGridViewHeaderCellStyle}"  Header="{Binding TimeFirst}" Width="0.8*" HeaderTextAlignment="Center"  ColumnGroupName="L1CODE">
                            <telerik:GridViewDataColumn.CellTemplate>
                                <DataTemplate>
                                    <Grid>
                                        <telerik:RadProgressBar  Height="20"  Minimum="0"  Maximum="3600" Value="{Binding L1CodeBeforeCnt3}" Style="{StaticResource l1code3progressbar}">
                                        </telerik:RadProgressBar>
                                        <TextBlock Text="{Binding L1CodeBeforeCnt3}" Margin="5 0">
                                        </TextBlock>
                                    </Grid>
                                </DataTemplate>
                            </telerik:GridViewDataColumn.CellTemplate>
                        </telerik:GridViewDataColumn>

and i used radpager like this.

 <telerik:RadGridView 
                            ItemsSource="{Binding PagedSource, ElementName=radDataPager}"
>

   <telerik:RadDataPager x:Name="radDataPager" 
                          Source="{Binding SignalCntData}" 
                          PageSize="30" 
                          />

this code works well in consists of basic controls.

is it a problem with styling the progressbar? but without pager, just radgridview, there are no problem..

But I must display more than 150 rows, I must use RadPager somebody help..

Hello,

I created an attached property that scrolls into the selected item when the SelectedItem changed (using the public method of the RadGridView).

This behavior was added because the selected item may be changed from other view. The RadGridView multi selection is enabled.

I noticed that during grouping, the scrolling into the selected item works, but the row might be collpased when the group IsExpanded property is false.

There is an easy way to expand the group?

I want to detect the group by O(1) and then update the IsExpanded property to True.

I am wondering what will happend if there are many groups? should I expand all of them or only the last one ?

I will be glad to know the easiest way for this.

* The performance is extremelly important so we should take into consideration that maybe the user selects a lot of items (let's say 250 out of 10000) so the SelectedItem will change a lot.
