My WPF Application is generating dynamic Buttons. I want to show these Button Horizontally. I wrote Code for this. Code is working fine but rather than showing button in Horizontal Direction, it is showing all Buttons in Vertical Direction! Where i also set Orientation of StackPanel!
Can anyone solve my Problem?
My Code is:
<Grid>
<dxlc:ScrollBox>
<ItemsControl x:Name="Buttonslist">
<ItemsControl.ItemTemplate>
<DataTemplate>
<StackPanel Orientation="Horizontal">
<Button Content="{Binding Text}" Tag="{Binding Text}" x:Name="New" Margin="5,0,5,0" Click="New_Click" />
</StackPanel>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
</dxlc:ScrollBox>
</Grid>
You're actually creating a StackPanel for each item/Button. To get just one for all the items you need to set the ItemsPanel of the control to a StackPanel.
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<Button Content="{Binding Text}" Tag="{Binding Text}" x:Name="New" Margin="5,0,5,0" Click="New_Click" />
</DataTemplate>
</ItemsControl.ItemTemplate>

I have encountered a problem - i have created a project where i bind my code to xaml by using a bind to the listbox. However, it has created some problems in my future code - i want to add button to my form, but i encounter some errors.
'Items collection must be empty before using ItemsSource.'
This Error occurs when i try to bind something outside of my bindable Listbox.
The property "VisualTree" can only be set once.
This Error occurs when i try to add button underneath the Listbox.
Can someone guide me on how can i fix this?
My code:
<ListBox x:Name="ItemsControl1">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="5">
</UniformGrid>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" BorderThickness="2" Width="Auto" Height="Auto">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Number}"/>
<Image Source="{Binding Source}" Margin="0,0,5,0"/>
</StackPanel>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
The desirable result would be a button under the listbox.
You should add your button below ListBox declaration.
Exceptions you are facing are thrown because visual tree is populated via binding and you cannot alter it manually anymore.
You will need to put all this stuff inside of some layout container (Grid, StackPanel, etc.), since you cannot set Window's/UserControl's Content property twice:
<StackPanel>
<ListBox x:Name="ItemsControl1">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<UniformGrid Columns="5">
</UniformGrid>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<Border BorderBrush="Black" BorderThickness="2" Width="Auto" Height="Auto">
<StackPanel Orientation="Horizontal">
<TextBlock Text="{Binding Number}"/>
<Image Source="{Binding Source}" Margin="0,0,5,0"/>
</StackPanel>
</Border>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
<Button/>
</StackPanel>
I have a VariableSizedWrapGrid, with buttons as items:
<Page.Resources>
<DataTemplate x:Key="LinkTemplate" x:DataType="local:LinkWeb">
<Button Width="100" Height="100" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" Margin="15,15,15,15" Click="Button_Click" >
<Button.Content>
<StackPanel>
<Image Source="{Binding ImageLink}" Margin="8,8,8,8" HorizontalAlignment="Center" Height="{Binding HeightImage}" Width="{Binding WidthImage}"/>
<TextBlock Text="{Binding Text}" TextWrapping="WrapWholeWords" />
</StackPanel>
</Button.Content>
</Button>
</DataTemplate>
</Page.Resources>
...
<ScrollViewer VerticalScrollBarVisibility="Auto" HorizontalScrollBarVisibility="Disabled" Grid.Row="1">
<ItemsControl x:Name="imageContent" ItemsSource="{Binding Enlaces}" ItemTemplate="{StaticResource LinkTemplate}" >
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<VariableSizedWrapGrid Orientation="Horizontal" ScrollViewer.HorizontalScrollBarVisibility="Disabled" HorizontalChildrenAlignment="Stretch" MaximumRowsOrColumns="2"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
</ItemsControl>
</ScrollViewer>
The VariableSizedWrapGrid shows two items per row, but the items appears aligned to the left, as you can see:
I need the VariableSizedWrapGrid shows the items centered in his content, like this:
Any idea about how I can achieve this?
EDIT
I've tried center the ScrollViewer, and, yes, items are "a little more centered", because VariableSizedWrapGrid inside ScrollViewer is centered, but, inside VariableSizedWrapGrid items float to the left, so items are not centered as you can see in this picture:
You could set the HorizontalChildrenAlignment property value of VariableSizedWrapGrid as Center. It should work.
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<VariableSizedWrapGrid Orientation="Horizontal" ScrollViewer.HorizontalScrollBarVisibility="Disabled" HorizontalChildrenAlignment="Center" MaximumRowsOrColumns="2" />
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
I want my custom build ListBox to display the items on the next line if their size exceeds the available width of their parent control.
Following is my XAML for this purpose.
<materialDesign:Card>
<StackPanel>
<TextBlock FontWeight="DemiBold" FontSize="30">Schedule</TextBlock>
<ListBox ItemsSource="{Binding Schedule, Source={StaticResource dc}}">
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
<ListBox.ItemTemplate>
<DataTemplate>
<ListBoxItem>
<StackPanel Orientation="Horizontal">
<StackPanel Orientation="Horizontal">
<TextBlock>Day:</TextBlock>
<TextBlock Text="{Binding Key, Mode=OneWay}" />
</StackPanel>
<materialDesign:TimePicker materialDesign:HintAssist.Hint="Time In" SelectedTime="{Binding Value.TimeIn}" />
<materialDesign:TimePicker materialDesign:HintAssist.Hint="Time Out" SelectedTime="{Binding Value.TimeOut}" />
</StackPanel>
</ListBoxItem>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
</StackPanel>
</materialDesign:Card>
Following is the Output for the above XAML
You should use a WrapPanel instead of a StackPanel, then.
As H.B. said, the ItemPanel control you should use is a WrapPanel that let you achieve what you want (when there isn't enough space for your control, it creates a new line).
Here it is an example:
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Horizontal"/>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
I do no know how to get the current item. If I did not need the button, it would work without the item template. Is there a better option instace of using ItemsControl?
Here's an example of how to do it using an ItemsControl:
<ItemsControl x:Name="ItemsControl" ItemsSource="{Binding Path=Items}">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.Resources>
<DataTemplate DataType="{x:Type local:Type1}">
<StackPanel>
<TextBlock Text="{Binding Property1}"/>
<TextBlock Text="{Binding Path=Property2, Mode=OneWay}"/>
</StackPanel>
</DataTemplate>
</ItemsControl.Resources>
</ItemsControl>
I am trying to display buttons dynamically on the screen in a wrap panel so that they are laid our nicely without any scrollbars. I have the markup as below, but the scrollbars appear for some reason. how do we make the scrollbar not appear and the buttons laid out without any scrollbars.
<ListBox x:Name="ItemsListBox" >
<ListBox.ItemTemplate>
<DataTemplate>
<ToggleButton Content="{Binding Name}" Click="Click" MinWidth="120" MinHeight="70" FontWeight="Bold" FontSize="18"/>
</DataTemplate>
</ListBox.ItemTemplate>
<ListBox.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel></WrapPanel>
</ItemsPanelTemplate>
</ListBox.ItemsPanel>
</ListBox>
What control is your ListBox inside? Most often the problem you descrive is caused by the parent control allowing the ListBox to grow.
You can prove whether this is the problem by setting an explicit Width="200" on your ListBox and testing what happens. If it wraps, then the problem is the ListBox's parent.
Add
ScrollViewer.VerticalScrollBarVisibility="Hidden"
ScrollViewer.HorizontalScrollBarVisibility="Hidden"
to you containers.
This does it what I was trying to achieve.
<ItemsControl x:Name="ListBox" Grid.Row="5" Grid.ColumnSpan="2">
<ItemsControl.ItemsPanel>
<ItemsPanelTemplate>
<WrapPanel Orientation="Vertical"/>
</ItemsPanelTemplate>
</ItemsControl.ItemsPanel>
<ItemsControl.ItemTemplate>
<DataTemplate>
<ToggleButton Content="{Binding Name}" MinWidth="120" MinHeight="50" FontWeight="Bold" FontSize="16" Margin="5"/>
</DataTemplate>
</ItemsControl.ItemTemplate>
</ItemsControl>
