RadComboBox - how do i prevent the ComboBox from changing SelectedItem until i click on one ?

I'm using the ComboBox with the autocompleter / text enabled search. 

I want to prevent the ComboBox from changing Selected Item until I actually click on an item or press enter... 

Currently the RadComboBox changes the SelectedItem when browsing the elements (arrow up or down) which is not desired.

<telerik:RadComboBox Width="150"
                                 Height="25"
                                 Margin="115,10,0,0"
                                 HorizontalAlignment="Left"
                                 VerticalAlignment="Top"
                                 DisplayMemberPath="FabrikatNavn"
                                 IsEditable="True"
                                 IsEnabled="{Binding CanChangeVariant}"
                                 ItemsSource="{Binding Source={StaticResource SortedBrands}}"
                                 OpenDropDownOnFocus="True"
                                 SelectedItem="{Binding ElementName=root, Path=BrandModel.SelectedCarBrand}"
                                 StaysOpenOnEdit="True" />

RadGridView: Databind to or manipulate the FullTextSearch

How the heck do i databind or manipulate the FullTextSearch Text ??

I've tried doing perfectly normal / sane / obvious databinding in XAML like this: 

<telerik:RadGridView TextSearch.Text="{Binding MyTextProperty}">

but that doesn't work - maybe because its not the correct property -- can't find it in documentation or as property on the radGridView instance..

I've also tried figuring out the binding example from this Forum called https://www.telerik.com/forums/bind-full-text-search-to-custom-textbox but failed to do so.. 

Why is the FullTextSearch String property not exposed in a normal behavior like with a DependencyProperty ???????

Why is this so hard ?

Why are the SearchPanel hardcoded instead of exposing a customizable panel ??

eg: If i want to add a button that clears all Search Filters , i need to make ugly hacks :(

White Line in Stacked Chart

We are using RadChartView to display some complex data. The requirement is to have a stacked column with 4 stacks above 0, 4 columns stacked below 0 and those need to have categories.

In XAML Code this looks like this:


<telerik:RadCartesianChart Tag="Text">
                    <telerik:RadCartesianChart.Grid> 
                        <telerik:CartesianChartGrid MajorLinesVisibility="Y" /> 
                    </telerik:RadCartesianChart.Grid> 
                    <telerik:RadCartesianChart.HorizontalAxis> 
                        <telerik:CategoricalAxis FontSize="11" LabelRotationAngle="45" LabelFitMode="Rotate" SmartLabelsMode="SmartStep"  /> 
                    </telerik:RadCartesianChart.HorizontalAxis> 
                    <telerik:RadCartesianChart.VerticalAxis> 
                        <telerik:LinearAxis LabelFormat="N2" SmartLabelsMode="SmartStep" /> 
                    </telerik:RadCartesianChart.VerticalAxis>
                    <telerik:RadCartesianChart.Series>
                        <telerik:BarSeries x:Name="CrNoScoreColumn"
                                           ToolTip="{}{Text}&#x0a;Summe: {y:n2}"
                                           ItemsSource="{Binding ChartDatas}"

I attach the chart as an image to this post. You can see there is a white line with around 1 pixel on every column. i can further say the border Y position and height make this white line.

The second clue i can give is that once i remove the negative series or make their value 0, the line is gone.

for example:


<DataTemplate x:Key="ElementCrDbColumnChart"
                          DataType="{x:Type charts:ChartDataContext}">

                </telerik:RadCartesianChart>
            </DataTemplate>

result in a chart with no white line. the same data. everything the same except for the barseries.

As a second side question: why is the line series not drawn? Any idea - it worked and some day without changes it disappeared and only the points are still drawn.

 

i hope we can get some solution here soon. we need this to work under any circumstances and with alle the above mentioned requirements. since we have telerik and componentone licences we will try to use their chart control for the time being but i would really want to use telerik if possible.

Bug: RadComboBox bugs the Visual Studio 2019 UI

While editing the XAML document, I'm experiencing weird behavior in VS2019. 

All examples applies when the Design editor is active together with XAML editor.

Example 1:

Selecting XAML with mouse stops when i start selecting the telerik:RadComboBox 

Example 2:

Copy Pasting bugs out, either the selection is empty or incorrect !

Example 3:

'Forcus' in Visual Studio is sometimes overtaken by the RadComboBox which is very annoying.

Floating RadNavigationView with no content

Hi All! Here is what I'm trying to achieve with the RadNavigationView (RNV):

  • Main content is full screen map in the background and through the RNV would toggle different overlays or options.
  • Depending on what the selecteditem is, show/hide/resize content area.

What's the best way to achieve that behavior with the RNV?

RadButton: CornerRadius ignored

I created a simple round button by setting Width and Height properties to the same size and CornerRadius to Width/2. Until now this worked perfect in my application.

After updating to R2.2021 (Telerik.UI.for.Wpf.NetCore, 2021.2.511) I noticed that buttons ignore the CornerRadius property when using the Fluent Theme. This was not the behavior in previous releases. 

Steps to reproduce:

  1. Create a WPF Core project (.NET Core 3.1)
  2. Add Telerik.UI.for.Wpf.NetCore (2021.2.511) via NuGet package manager
  3. Modify App.xaml to include all resource dictionaries necessary for Fluent Theme
  4. Create a button:
<telerik:RadButton Content="DOH!"
                   Height="100" Width="100"
                   CornerRadius="50" />

The button is just a square, not round. When changing the theme to e. g. VisualStudio 2019 the button is round again. (see attached pictures)

Heiko

The line are connected to the wrong dot

I have a LineSeries where I can add new points by clicking on the chart.

Most of the time everything is fine but sometimes the lines are connected to the wrong point.

It only happens when the time values are close to each other.

If I close the page with the chart and open it again the lines are drawn correctly.

1. Is there a way to get the chart to draw the line correct?

2. If not 1. Then can I somehow force a refresh of the chart?
