We've got a RadCartesianChart with a BarSeries. We added the ChartTooltipBehaviour with a custom ContentTemplate. It's difficult to hover the mouse over bars with very small or zero values to get the tooltip to show, so I enabled `SnapToClosestPoint` for the tooltip. This works great for getting the tooltip to appear when hovering in the area above a bar, but if the tooltip gets rendered at a location where the mouse pointer is inside the tooltip, then the tooltip appears, disappears, appears, disappears, etc.

Has anyone else run into this issue? Anyone solved it?

Hi again,

I'm almost finished moving from standard ListView components to the RadListView and currently am looking at dragging items from one list to another.

I couldn't find any demo's/examples of this.  When I try it, I can't seem to get the item to drag out of the lists border.

Is there a pre-requisite to enable this?

Thanks,

Rob.

Hi there,

I am using the RadListView on UWP.

I have applied filtering in XAML.  There are multiple filters applied.

How do I refresh one (or all) of those filters when an external comparison value changes?

 

For example;

Say you have a checkbox outside of the radlistview.  The listviews have a delegate filter comparing a property of each item in the collection to the checkbox boolean value.

When that checkbox boolean changes, you want to refresh/re-apply the filter.

How do I do this refresh?

Thanks,

Rob.

Steps to replicate:

1. run VS 2019 v

2. create a new UWP project using VB.NET

3.  prompt appears for login credentials? (see attached image)

Error is listed:

"Failed to download package 'Microsoft.Net.UWPCoreRuntimeSdk.2.2.9' from 'https://api.nuget.org/v3-flatcontainer/microsoft.net.uwpcorerutimesdk/2.2.9/microsoft.net.uwpcoreruntimesdk.2.2.9.nupkg'.  The ServicePointManager does not support proxies with https scheme."

What/where are this credentials??  (they aren't my telerik account credentials, that much I know)

Cheers, Rob.

In my grid data column I cannot set the minimum and maximum value. I thought it works like the RadNumericBox.

Can a RadDataGrid have a two way binding?

Whenever I edit a cell in the following TwoWay binded grid, the source collection is not updated. Is this the defined behaviour?

 

 

<tg:RadDataGrid x:Name="radGrid"
Grid.Row="1"
  Style="{StaticResource RadDataGridInsideStyle}"
  ColumnDataOperationsMode="Inline"
  ItemsSource="{x:Bind ViewModel.TrainingsSummary, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
  AutoGenerateColumns="False"
  UserGroupMode="Disabled"
  UserEditMode="None"
  MinWidth="400"

 

The source collection is defined as follows:

 

public ObservableCollection<OverviewTrainingsReportDTO> TrainingsSummary { get; set; } = new ObservableCollection<OverviewTrainingsReportDTO>();
