Show/Hide items in itemscontrol on condition
c#-4.0, itemscontrol, wpf, xaml
Solution
Why don't you try using the `Visibility` property? you just have to create a public property in your MVVM or code behind and the Bind it to the element you want to hide.
<StackPanel Visibility="{Binding ShowElement, Converter={StaticResource VisibilityConverter}, Mode=TwoWay}">
By setting the boolean value of ShowElement, you can easily hide or show the StackPanel.
Problem
I have an Itemscontrol that I am using to display a list of start information sent from a timing system. I need to be able to "switch off"/stop displaying a set of lane info if the lane number isn't showing (if it's null or a blank) and then if the timer sends info to switch the lane back on then show the data again. I can't set it to just delete everything because the timer sends its information constantly and everything except the lane number would reappear again. Is it possible to show/hide items on condition? What is currently happening ``` Lanes 1 ------ 2 ------ ------ <- other info remains 4 ------ ``` What I want to happen ``` Lanes 1 ------ 2 ------ 4 ------ ``` Here is a sample of my itemscontrol code ``` <ItemsControl ItemsSource="{Binding CHeat.SwimList}" Margin="10,0" HorizontalAlignment="Left" VerticalAlignment="Top"> <ItemsControl.Template> <ControlTemplate TargetType="ItemsControl"> <StackPanel> <StackPanel Orientation="Horizontal"> <Label Content="Lane" /> <Label Content="Pos" /> <Label Content="Swimmer" /> <Label Content="Club" /> <Label Content="Time" /> </StackPanel> <ItemsPresenter/> </StackPanel> </ControlTemplate> </ItemsControl.Template> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <StackPanel/> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> <ItemsControl.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width="35" /> <ColumnDefinition Width="30" /> <ColumnDefinition Width="150" /> <ColumnDefinition Width="50" /> <ColumnDefinition Width="80" /> </Grid.ColumnDefinitions> <Label Grid.Column="0" Content="{Binding LaneNumber}" /> <Label Grid.Column="1" Content="{Binding Position}" /> <Label Grid.Column="2" Content="{Binding Swimmer}" /> <Label Grid.Column="3" Content="{Binding Club}" /> <Label Grid.Column="4" Content="{Binding Time}" /> </Grid> </StackPanel> </DataTemplate> </ItemsControl.ItemTemplate> </ItemsControl> ``` If there was a way I could set `Content = ""` for the other data based off the LaneNumber then I believe it could work, because then I can just bring back the bindings. I'm fairly new to WPF so extra detail would be helpful many thanks!
