How to bind an object to a list of check boxes?

Question

Have a list of check boxes below:

<GridView x:Name="GvCategories" Margin="10,0,0,10">
                            <GridView.ItemTemplate>
                                <DataTemplate>
                                    <Grid>
                                        <CheckBox x:Name="CbCategory" Content="{Binding Name}" Foreground="#FF0A0A0A" Checked="CbCategoryChecked" Unchecked="CbCategoryUnchecked"/>
                                    </Grid>
                                </DataTemplate>
                            </GridView.ItemTemplate>
                            <GridView.ItemsPanel>
                                <ItemsPanelTemplate>
                                    <WrapGrid MaximumRowsOrColumns="6"/>
                                </ItemsPanelTemplate>
                            </GridView.ItemsPanel>
                        </GridView>

These check boxes represents categories with ID's. I need to save the category ID's of the categories that was selected. A list of category objects is bound to the gridview from the page's viewmodel class. How do I bind the ID or category object to the check box?

Answer 1

Binding the checkbox to a Boolean isn't difficult:

IsChecked="{Binding CheckedValue}"

But I'm not sure that's what you're asking for.  What do you want the end result to be?

NOTE: If I ask for code, please provide something that I can drop directly into a project and run (including XAML), or an actual application project. I'm trying to help a lot of people, so I don't have time to figure out weird snippets with undefined objects and unknown namespaces.

Answer 2

Wanted the object (to get id property) that's currently bound to the instance of the check box in the checked event handler. I figured it out by grabbing the datacontext of frameworkelement which is the gridview.

Answer 3

Try to bind the object itself with CheckBox's Tag property. So you get get all the properties of object.
