I want to select multiple rows by selecting one and then holding down the shift key and selecting more.
For example in WPF DataGrid there is an Extended multiple selection option: https://docs.telerik.com/devtools/wpf/controls/radgridview/selection/multiple-selection
Current working behavior: when setting the offset and gradient colors to bar indicator, the gradient is drawn based on the indicator size. I want to draw the gradient based on the axis size.
Current behavior:
Scenario I want to achieve:
Ran into this issue - which seems to be dependent on how the content gets rendered, so it will fail 100% of the time on specific configurations, resulting in unusable applications.
I've found this issue on Android but there's no telling if the issue is cross platform - as it may depend on item sizings and layout, it may also be reproducible on other platforms, I just haven't hit it yet. The device you run it on may also influence the result, as different resolutions and scalings will impact how items are rendered on screen. I've reproduced this on a Pixel 7 (real device), Samsung A21s (real device) and Pixel 7 Pro (emulator).
Repro steps
MainPage.xaml - use this as the page content:
<ScrollView Padding="15,0,15,15">
<VerticalStackLayout Spacing="25">
<telerik:RadWrapLayout
x:Name="BrokenLayout"
Margin="-5"
SizeChanged="BrokenLayout_SizeChanged"
StretchLastChild="False">
<BindableLayout.ItemTemplate>
<DataTemplate>
<Grid
Margin="3.75"
Padding="3.75"
BackgroundColor="LightGreen">
<Label
FontAttributes="Bold"
FontSize="11"
LineBreakMode="TailTruncation"
MaxLines="2"
Text="{Binding}"
VerticalOptions="End" />

In popup mode when scaling is 75%, tapping outside close to the view border does not work, the control keeps the width and height as in 100%
in drop down mode the drop-down is not close to the picker, there is a height between them.
add a button control in which you can swipe its content
Currently, i can use the public method ScrollItemIntoView to scroll to an item in the DataGrid.
I noticed you have an internal method: ScrollColumnIntoView. Please make it public so I can use it to scroll to a specific column.
Hi Team,
We have a scenario where our license key file is hosted on a team-only file share. However, the file share only works with HTTP/S links and not a UNC path.
For example, this works perfectly:
TELERIK_LICENSE_PATH="\\internalshare\folder\telerik-license.txt"
However, we cannot use
TELERIK_LICENSE_PATH="http://internalshare.com/telerik-license.txt"
Thank you,
Teddy
In MAUI CollectionView when scrolling an item into view, the exact position of the item after the scroll has completed can be specified with the position argument of the ScrollTo methods.
Please provide such option for Telerik MAUI CollectionView inside the ScrollItemIntoView method.
