Having this setup:
<telerikDataGrid:DataGridTemplateColumn HeaderText="Age"
CanUserSort="True">
<telerikDataGrid:DataGridTemplateColumn.CellContentTemplate>
<DataTemplate>
<Label Text="{Binding Age}" />
</DataTemplate>
</telerikDataGrid:DataGridTemplateColumn.CellContentTemplate>
<telerikDataGrid:DataGridTemplateColumn.SortDescriptor>
<telerikCommon:PropertySortDescriptor PropertyName="Age" SortOrder="Descending" />
</telerikDataGrid:DataGridTemplateColumn.SortDescriptor>
</telerikDataGrid:DataGridTemplateColumn>
When applying SortDescriptor to the Template column, the column is not initially sorted.
DataGrid is added inside pages that can be accessed through shell flyout menu.
And the exact steps to reproduce the issue:
Go to page GridOne page in flyout menu.Enter any element by double tap. this navigates to another page - SubGridPage
On SubGridPage again double tap any element. this navigates to another page - InnerModel
When you are in InnerModel page select from flyout menu GridTwo page
On GridTwoPage double tap any element, this navigates to another page - SubGridPage
On SubGridPage double tap any element. this navigates to another page - InnerModel
When you land on InnerModel page go back to Grid One on flyout menu.
When you are in the GridOne InnerModel, press the back arrow.
It navigates to the SubGridPage. but the DataGrid is not visualized.
Provide right to left support.
Currently I can change the IsBusy background color by using implicit style:
<ContentPage.Resources>
<ResourceDictionary>
<Style TargetType="telerik:RadBusyIndicator" x:Name="busy">
<Setter Property="BackgroundColor" Value="Red"/>
</Style>
</ResourceDictionary>
</ContentPage.Resources>
<telerik:RadDataGrid IsBusy="True"/>
It would be really nice to have a RichTextBox control for .NET MAUI that worked on all platforms including Windows and Mac. I'm trying to migrate an application from WPF to MAUI and MAUI simply does not have a RichTextBox equivalent.
Telerik had something already for Xamarin called RichTextEditor but I believe it only works on iOS/Android and not Mac/Windows.
If you could do it quickly, you'd actually be the first company to have one as well, as from what I have been able to glean from my research, no company offers one as of yet, hence my predicament.
Thanks!
Changing the ItemsSource property of the ListView causes it to recreate its cells. The problem is that the existing cells are never reclaimed by the garbage collector, so the memory usage grows constantly. Eventually, the application can run out of memory, if the ItemsSource is updated too many times.
Note: It is possible the memory leak is caused by the bindings holding objects longer than necessary. Similar memory leaks can be reproduced with the .NET MAUI CollectionView as well. Here are a few GitHub issues for the CollectionView that might be related:
- CollectionView leaks memory when ItemsSource has changed
- Massive memory leak in CollectionView while scrolling
- Memory leaks EVERYWHERE
Header Text, group header text, do not display some languages characters like Chinese, Thai, etc.
The root reason for this is the fact that the Skia APIs used to draw the text does not support automatic character fallback.
Workaround:
for header text:
<telerik:DataGridTextColumn.HeaderContentTemplate>
<DataTemplate>
<Label Text="your text"></Label>
</DataTemplate>
</telerik:DataGridTextColumn.HeaderContentTemplate>group header text
<telerik:RadDataGrid.GroupHeaderTemplate>
<DataTemplate>
<Label Text="{Binding Group.Key}"/>
</DataTemplate>
</telerik:RadDataGrid.GroupHeaderTemplate>column:
<telerik:DataGridTextColumn HeaderText="Name" >
<telerik:DataGridTextColumn.CellContentTemplate>
<DataTemplate>
<Label Text="{Binding Name}"/>
</DataTemplate>
</telerik:DataGridTextColumn.CellContentTemplate>
</telerik:DataGridTextColumn>
Hi,
I'am testing Telerik .NET MAUI controls for windows and android. FontFamily property of columns (both for xaml and app.xaml) not working. If an embedded font is choosen for whole application, DataGrids look different from other parts of the application
here is my xaml, "fnt_bold" is a MauiFont in resources. All other ui components are shown in my font
<telerik:RadDataGrid x:Name="dataGrid" AutoGenerateColumns="False" UserEditMode="None" UserGroupMode="Disabled" SelectionMode="Single" SelectionUnit="Row" >
<telerik:RadDataGrid.Columns>
<telerik:DataGridTextColumn PropertyName="ID" HeaderText="RefID" Width="60" SizeMode="Fixed">
<telerik:DataGridTextColumn.CellContentStyle>
<telerik:DataGridTextCellStyle FontFamily="fnt_bold" FontSize="12.25"/>
</telerik:DataGridTextColumn.CellContentStyle>
</telerik:DataGridTextColumn>
<telerik:DataGridTextColumn PropertyName="CODE" HeaderText="Code" Width="80" SizeMode="Fixed">
<telerik:DataGridTextColumn.CellContentStyle>
<telerik:DataGridTextCellStyle FontFamily="fnt_bold" FontSize="12.25"/>
</telerik:DataGridTextColumn.CellContentStyle>
</telerik:DataGridTextColumn>
<telerik:DataGridTextColumn PropertyName="NAME" HeaderText="Name" Width="250" SizeMode="Fixed">
<telerik:DataGridTextColumn.CellContentStyle>
<telerik:DataGridTextCellStyle FontFamily="fnt_regular" FontSize="12.25"/>
</telerik:DataGridTextColumn.CellContentStyle>
</telerik:DataGridTextColumn>
</telerik:RadDataGrid.Columns>
</telerik:RadDataGrid>I have attached a screenshot from my test app.
I also checked the sample telerik android app (Telerik UI for .NET MAUI Controls). DataGrid components in Telerik Sample app also dont use the expected font unlike all other ui components.
Just one of the DataGrid samples of one column in the sample app has the correct fontfamily property. I have attached that screenshot also. I couldn't figure out how to implement it.
Am i missing something?
Thanks in advance.

When I register the pages and controls using AddTransient it works but when I use AddSingleton it doesn't.
