We use a Maui RadTimePicker. We regulary update the Time Property from code behind to provide the user with a meaningful starting value.
But if the popup is open, an Update of the Time Property currently changes the current user selection. It's confusing for the user if his selection get's magically changed. Potentially right before he hits ok.
From my point of view the current behaviour is a bug.
Workaround for us would be to try to detect if the popup is open and not update the Time Property in this case. But how can we detect in code if the popup is showing?
Thanks,
Karsten

Hi
I'm getting the following Binding errors when using the Date or Time picker.
'BorderBrush' property not found on 'Telerik.Maui.Controls.PickerDateSelector', target property: Telerik.Maui.Controls.RadBorder.BorderBrush'
This happens regardless of the settings or style applied (at least to my knowledge) and Android and iOS. See below for example
<telerik:RadDatePicker HeightRequest="50" IsClearButtonVisible="True" Date="10,10,10" />
<telerik:RadTimePicker HeightRequest="50" IsClearButtonVisible="True" Time="10" />

Hello,
I have several controls I want to change the font size and text color for (RadNumericInput, RadTimePicker, and RadTimeSpanPicker). The pop-ups are fine out of the box but the control itself (before being tapped on) has fairly small font and the font is black which doesn't work in Dark Mode. I would like to make the font larger for each of these 3 controls and bind the Text Color to a Color in my Theme so the text color updates based on the theme being Dark vs Light. I'm assuming I would do these changes for all the controls in a similar way, but I am fairly new to Telerik UI. I just don't seem to find a TextColor or FontSize exposed as either an attribute, property, etc. for any of the Rad controls. I must be missing something simple, as every basic control has ability to change text color and size.
I would appreciate any help somebody could provide. Thank you.
p.s. - Bonus points if you can tell me how to do it in C# rather than XAML, but OK if not. I can adapt it as needed. :)

Hi , actually it is long term issue, it is here few Telerik versions already, this time it appeared again. Issue is - some telerik controls are working thru http://schemas.telerik.com/2022/xaml/maui namespace but some are not. Have to use clr-namespace:Telerik.Maui.Controls;assembly=Telerik.Maui.Controls . Very annoying. Today after upgrade i have to go thru all source files (xaml) and change it again. Below is example of issue, assume i have 20+ xaml files there... Yes, i did clean, rebuild etc.

Hello, I am trying to set a custom CellEditTemplate for a Date Column so that I can make it edit the time not just the date, but the binding is not working at all.
And it says this error: "Binding: 'Time' property not found on 'Telerik.Maui.Controls.Compatibility.DataGrid.DataGridCellEditContext', target property: 'Telerik.Maui.Controls.RadTimePicker.Time'"
<telerik:DataGridDateColumn PropertyName="Time"
HeaderText="Time">
<telerik:DataGridColumn.CellEditTemplate>
<DataTemplate>
<telerik:RadTimePicker Time="{Binding Time}"></telerik:RadTimePicker>
</DataTemplate>
</telerik:DataGridColumn.CellEditTemplate>
</telerik:DataGridDateColumn>
