Hey,

I am trying to create a Telerik Data Grid (RadGridView) which styles each line dynamically based on some data triggers. I am using VS2019, .NET 4.6 WPF with Telerik 2019.2 NOXAML.

As I did not know how I searched the web (including this forum) and identified a basic solution. Using

<telerik:RadGridView.RowStyle>
    <Style TargetType="telerik:GridViewRow">
        <Setter Property="Background" Value="Red"/>
        <Setter Property="Foreground" Value="White"/>
    </Style>
</telerik:RadGridView.RowStyle>

I should be able to style every row red/white (for starters ...). This is from the example here (https://docs.telerik.com/devtools/wpf/controls/radgridview/styles-and-templates/styling-a-row) which is not really good because it does not tell me HOW to define it exactly on my grid. However I also found an example from the forum from 2010 (https://www.telerik.com/forums/setting-radgridview-row-background-color-based-on-the-value-of-a-column-in-the-row) which uses the styling as you see above. The example works however my grid simply shows "nothing" as soon as I use the style definition.

This is my grid which I simplified for you:

App.xml:

<ResourceDictionary>
    <ResourceDictionary.MergedDictionaries>
        <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8Touch;component/Themes/System.Windows.xaml"/>
        <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8Touch;component/Themes/Telerik.Windows.Controls.xaml"/>
        <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8Touch;component/Themes/Telerik.Windows.Controls.Input.xaml"/>
        <ResourceDictionary Source="/Telerik.Windows.Themes.Windows8Touch;component/Themes/Telerik.Windows.Controls.GridView.xaml"/>
    </ResourceDictionary.MergedDictionaries>
</ResourceDictionary>

Grid.xml:

<telerik:RadGridView ItemsSource="{Binding MyObservableList}" AutoGenerateColumns="False" RowIndicatorVisibility="Collapsed">
    <telerik:RadGridView.RowStyle>
        <Style TargetType="telerik:GridViewRow">
            <Setter Property="Background" Value="Red"/>
            <Setter Property="Foreground" Value="White"/>
        </Style>
    </telerik:RadGridView.RowStyle>
        
    <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding idx}" Header="ID" />
        <telerik:GridViewDataColumn DataMemberBinding="{Binding Description}" Header="Description" />
    </telerik:RadGridView.Columns>
</telerik:RadGridView>

Hello guys.

Im using Telerik 2015 Q3 for WPF (2015.3.930.45) and i have a problem with the tabindex inside mi form.

I have a form with several RadComboBox, textboxes...

If I place a textbox (Tabindex = 0), a radcombobox (Tabindex = 1) and anoche textbox (Tabindex = 2), when i press tab in the first textbox focus goes to the other textbox, and then, the next focused item is the radcombobox.

Its like ui always focus windows UI controls before radcombobox.

How can I solve this problem? I need that tabindex works like it should work...

Hello 

Our horizontal axis is always a frequency, is it possible to display the unit kilo/Meg/Gig,
for example display 1.2 GHz, 100kHz, 10MHz instead of 1200000 Hz, 100000Hz, 10000000Hz ?

thanks

Hey,

I have the problem with a gridview. When I cancel the Rowedit with pressing 'Esc' two times the row not fully cancels. As you can see in my video.

(https://www.dropbox.com/s/ctpiyfsq0v3vyx2/Record100919.wmv?dl=0)

The previously in the same row entered value is still visible. As soon as you click in the cell, it disapears. If  I not click into it and change another cell, it even writes the before cancelled value into the cell.

I not have something really special there. The radgridview itemsource is a Datatable set in C#:                

rgvTeile.ItemsSource = Daten.GibTeileWithReklamationsID(aktReklamationsID).DefaultView;

This is my radgridview:

                            <telerik:RadGridView
                                Grid.Row="3"
                                x:Name="rgvTeile"
                                Margin="0 10 0 0"
                                AutoGenerateColumns="False"
                                GroupRenderMode="Flat"
                                ShowGroupPanel="False"
                                FilteringMode="Popup"
                                ShowSearchPanel="False"
                                ValidatesOnDataErrors="InEditMode"
                                EnableColumnVirtualization="False"
                                NewRowPosition="Bottom"
                                HorizontalAlignment="Left"
                                RowEditEnded="RgvTeile_RowEditEnded"
                                ActionOnLostFocus="CommitEdit"
                                >
                                <telerik:RadGridView.Columns>
                                    <telerik:GridViewDataColumn
                                        DataMemberBinding="{Binding ID}"
                                        Header="ID"
                                        IsVisible="False"
                                        IsReadOnly="True"
                                        />
                                    <telerik:GridViewDataColumn
                                        DataMemberBinding="{Binding Menge}"
                                        Header="Menge"
                                        />
                                    <telerik:GridViewDataColumn
                                        DataMemberBinding="{Binding Bezeichnung}"
                                        Header="Bezeichnung"
                                        />
                                    <telerik:GridViewDataColumn
                                        DataMemberBinding="{Binding ArtikelNummer}"
                                        Header="ArtikelNummer"
                                        />
                                    <telerik:GridViewDataColumn
                                        DataMemberBinding="{Binding Farbe}"
                                        Header="Farbe"
                                        />
                                    <telerik:GridViewDataColumn
                                        DataMemberBinding="{Binding Fertigmaß}"
                                        Header="Fertigmaß"
                                        />
                                </telerik:RadGridView.Columns>
                            </telerik:RadGridView>

Hi,

I have a RadTreeMap that's working perfectly except that I want its labels to be centered vertically and horizontally within each rectangle.

I'm also using a Colorizer:

<telerik:TypeDefinition.Mappings>
      <telerik:DesaturationColorizer From="1" To="0.1" StartColor="#d9ac26"/>
</telerik:TypeDefinition.Mappings>

...so, when I attempt to change use a TextBlock with the proper alignment:

<Style TargetType="telerik:RadTreeMapItem">

     <Setter Property="Template">
           <Setter.Value>
                <ControlTemplate>
                     <TextBlock Text="{Binding Label}" HorizontalAlignment="Center"  VerticalAlignment="Center"/>
                 </ControlTemplate>
            </Setter.Value>
       </Setter>
</Style>

...it successfully centers the labels, but I lose the colorizing effect. How can I make the TextBlock respect the intended colorizing?

As I see when RT control import and export back, it cleans custom attributes.

id tag is required for styles as i understand, but what about my own attribute "data-id" (by html specification all data-* attributes are user defined attributes)?

Is it any solution to prevent remove user custom attributes?

Hello 

Is it possible to do a datareduction so we dont display all the points : Handle
one million points (5 series of 200 000), and display one point by pixel (with
only the maximum level for each pixel. So one million points are never
displayed at the same time and we do datareduction.

Hi there,

Does anyone know how we can have an endless horizontal scrolling? Basically, I want to be able to change the visible range of ganttview dynamically as user clicks on the right/left thumb of horizontal scrolling.

Thanks,
