Still fooling around with WPF and learning as I go. Trying now to build a dynamic grouping of controls (mostly Buttons but might include CheckBoxes and others).
I had no idea what was the best way to do this so I tried creating a ItemsControl style and then add the items into a ItemsPresenter inside a WrapPanel. Soon realized the items wouldn't wrap because they effectively weren't inside the WrapPanel unless I put it as ItemsHost. Like this:
<Style x:Key="ButtonPanelGroup" TargetType="{x:Type ItemsControl}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ItemsControl}">
<Border CornerRadius="5"
BorderBrush="{StaticResource DarkColorBrush}"
BorderThickness="1"
Margin="5">
<Grid>
<Grid.RowDefinitions>
<RowDefinition />
<RowDefinition Height="Auto" />
</Grid.RowDefinitions>
<WrapPanel IsItemsHost="True" FlowDirection="LeftToRight">
<ItemsPresenter />
</WrapPanel>
<ContentPresenter ContentSource="Name" Grid.Row="1" />
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
Note that this is a work in progress and there are many styling effects I still need to implement. Here I use it:
<UniformGrid Rows="1">
<ItemsControl Name="Group1" Style="{StaticResource ButtonPanelGroup}">
<Button>Button1</Button>
<Button>Button2</Button>
<CheckBox>TickBox</CheckBox>
</ItemsControl>
<ItemsControl Name="Group2" Style="{StaticResource ButtonPanelGroup}">
<Button>Button3</Button>
<Button>Button4</Button>
<Button>Button5</Button>
</ItemsControl>
<ItemsControl Name="Group3" Style="{StaticResource ButtonPanelGroup}">
<Button>Button6</Button>
<Button>Button7</Button>
<Button>Button8</Button>
</ItemsControl>
</UniformGrid>
Also note here that it is still a work in progress as UniformGrid wouldn't be the way to go here and also margins can be a pain (are there any margins that overlap?) so input there would be appreciated.
Now to the real problem. This doesn't work I get a error:
'ItemsPresenter' object cannot be added to 'WrapPanel'. Cannot explicitly modify Children collection of Panel used as ItemsPanel for ItemsControl. ItemsControl generates child elements for Panel. Error at object 'System.Windows.Controls.ItemsPresenter'.
So what's the best way to do something like this ( would love to be able to just throw buttons and other controls into the ItemControl and the line up real nice ). Would it be better to put the Controls into a collection of some kind and iterate.
Would love to get it nicely done but my WPF skills are still lacking. Are there any WPF books that teach beyond the basics and show how pro's would really do it?
