CheckBox MultiBindings
-
Hey All, I have a question about MultiBinding on multiple check boxes that I can't seem to figure out. For argument sake lets say I have three checkboxes in a group. Two of which could be described as children of the master checkbox. There are in turn three boolean properties on the datacontext object that need to be kept up to date with the contents of all three checkboxes. The master checkbox has a multibinding set to the two child checkboxes so if either is checked the master becomes checked and if the master is checked the two children become checked ... What I can't figure out is how to keep the 'master' property for the master checkbox updated with the master checkbox IsChecked value. This is easy if you start roaming into C# land but I want to do this purely in XAML ... The code I have is like this at the moment:
<CheckBox Margin="5"
Style="{DynamicResource BlackTextOnLeft}"
Width="325">chkBox1
<CheckBox.IsChecked>
<MultiBinding Converter="{StaticResource masterConfigCheckBoxConverter}">
<Binding Path="IsChecked" ElementName="chkBox2" Mode="TwoWay" />
<Binding Path="IsChecked" ElementName="chkBox3" Mode="TwoWay" />
</MultiBinding>
</CheckBox.IsChecked>
<CheckBox>Any pointers would be great ... Cheers,
