This document describes how to use the TableView control. I notice that every example in this doc displays items in one column. Because TableView is a table, I guess it can display items in multiple columns. However I can't find the way to do it. Does anyone know how to do it?
There is an example in that document itself that uses a default ViewCell and creates two columns with Grid: https://learn.microsoft.com/en-us/dotnet/maui/user-interface/controls/tableview#view-cell
<TableView Intent="Settings">
<TableRoot>
<TableSection Title="Silent">
<ViewCell>
<Grid RowDefinitions="Auto,Auto"
ColumnDefinitions="0.5*,0.5*">
<Label Text="Vibrate"
Margin="10,10,0,0"/>
<Switch Grid.Column="1"
HorizontalOptions="End" />
<Slider Grid.Row="1"
Grid.ColumnSpan="2"
Margin="10"
Minimum="0"
Maximum="10"
Value="3" />
</Grid>
</ViewCell>
</TableSection>
</TableRoot>
</TableView>
Good luck
I have a list of many records and i want to show each record on one single page.
What i want is, When we do swipe up from bottom of the page, next record in list should show with animation. similarly, when we do swipe down from top of the page, previous record in list should show with animation.
I don't know how to achieve this. hope for better solution
Caraousel View with orientation and snap points should give you desired results
<CarouselView BindingContext="{x:Reference BottomTabGridPageXaml}" ItemsSource="{Binding StudentList}"
VerticalOptions="FillAndExpand">
<CarouselView.ItemsLayout>
<LinearItemsLayout Orientation="Vertical" SnapPointsType="MandatorySingle"/>
</CarouselView.ItemsLayout>
<CarouselView.ItemTemplate>
<DataTemplate>
<StackLayout VerticalOptions="FillAndExpand">
<Label Text="{Binding Id}" HorizontalOptions="Center" VerticalOptions="CenterAndExpand"/>
<Label Text="{Binding Name}" HorizontalOptions="Center" VerticalOptions="CenterAndExpand"/>
<Label Text="{Binding Number}" HorizontalOptions="Center" VerticalOptions="CenterAndExpand"/>
<Label Text="{Binding Age}" HorizontalOptions="Center" VerticalOptions="CenterAndExpand"/>
</StackLayout>
</DataTemplate>
</CarouselView.ItemTemplate>
</CarouselView>
Here is the XAML code that I created:
<ViewCell>
<Grid VerticalOptions="CenterAndExpand" Padding="20, 0">
<Label HorizontalOptions="StartAndExpand" Text="ABC" />
<Entry Keyboard="Numeric" VerticalOptions="Center" HorizontalOptions="End" />
</Grid>
</ViewCell>
When I run the code the data entry area for the window is only wide enough to show one digit. Is there a way I can expand this so it will allow me to enter three digits?
Set a WidthRequest value, and also try changing the HorizontalOptions
<Entry Keyboard="Numeric" VerticalOptions="Center" WidthRequest="100" HorizontalOptions="FillAndExpand" />
Here's the code I was using:
<Label x:Name="detail3" Grid.Row="2" FontSize="35" XAlign="Center" VerticalOptions="Center" LineBreakMode="WordWrap" />
But I understand XAlign should no longer be used.
XAlign has been deprecated for the better named HorizontalTextAlignment
Similarly YAlign has been deprecated for VerticalTextAligment
So to horizontal align the text for your Label you can do the following:
<Label x:Name="detail3" Grid.Row="2" FontSize="35" VerticalTextAlignment="Center" HorizontalTextAlignment="Center" LineBreakMode="WordWrap" />
See https://developer.xamarin.com/api/type/Xamarin.Forms.Label/
HorizontalTextAlignment
Center, End, or Start, to indicate the
horizontal placement of the label text.
VerticalTextAlignment
Center,
End, or Start, to indicate the vertical placement of the label text.
Please check Xamarin documentation
Xamarin.Forms.Label.XAlign Property
If you want to Label control in centre align use the -HorizontalOptions="Centre"
<Label x:Name="detail3" Grid.Row="2" FontSize="35" XAlign="Center" VerticalOptions="Center" HorizontalOptions="Centre" LineBreakMode="WordWrap" />
If you want to Label's text in centre align use the -HorizontalTextAlignment="Centre"
<Label x:Name="detail3" Grid.Row="2" FontSize="35" XAlign="Center" VerticalOptions="Center" HorizontalTextAlignment="Centre" LineBreakMode="WordWrap" />
I'm having a cell view with nested StackLayouts, there's one label that will be wrapped if the text is long, which is the desired behaviour. However, the wrap breaks the LayoutOptions set to (basically) all parent views resulting in a gray gap on the right hand side.
<StackLayout Orientation="Horizontal" BackgroundColor="Gray" Margin="0,30,0,0">
<BoxView
HorizontalOptions="Start"
BackgroundColor="#EEBB00"
WidthRequest="100"
/>
<StackLayout
BackgroundColor="#CC4400"
HorizontalOptions="FillAndExpand"
>
<BoxView
BackgroundColor="Green"
HeightRequest="10"
HorizontalOptions="FillAndExpand"
/>
<Label
FontSize="16"
HorizontalOptions="FillAndExpand"
Text="Name that is toolongandwillbewrapped"
/>
<StackLayout
Orientation="Horizontal"
HorizontalOptions="FillAndExpand"
BackgroundColor="Blue"
>
<Label
FontSize="13"
Text="Left"
TextColor="White"
HorizontalOptions="StartAndExpand"
VerticalTextAlignment="End"
/>
<Label
FontSize="13"
Text="Right"
TextColor="White"
HorizontalOptions="EndAndExpand"
VerticalTextAlignment="End"
/>
</StackLayout>
</StackLayout>
</StackLayout>
The resulting views are:
So I can tell why this is happening, but well, of course I don't like it. The expected behaviour is for the right-hand-side stacklayout to expand all the way to the right. I've tried various ways to circumvent this and would not be here if I had succeeded. Does anybody have an idea?
Unfortunately, it's a bug in Xamarin.Forms (probably, iOS-only).
Bugzilla #28650
Bugzilla #31128
Bugzilla #33841
The workaround in that case is using Grid instead of StackLayout : http://forums.xamarin.com/discussion/comment/152969/#Comment_152969
