Select Checkbox inside a ListView programmatically

Question

How can I select a CheckBox inside a ListView via code? I found some code online to check the boxes but checked property is not available in windows phone 8.1

foreach (ListViewGroup grp in listFiles.Groups)
{
    foreach (ListViewItem item in grp.Items)
    {
        if (item.Index != 0)
        {
            item.Checked = true;
        }
    }
}

the xaml code is

<ListView x:Name="ContentListView" SelectionMode="Multiple">
    <ListView.ItemTemplate>
        <DataTemplate>
            <TextBlock Foreground="Black" Text="{Binding}" FontSize="25"></TextBlock>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

The checkboxes are automatically generated checkboxes of listview

The Checked property is available on CheckBox, in this code you are however iterating ListViewItems, not CheckBoxes. Without your view (e.g. XAML) it's impossible to guess where your CheckBoxes really are. — Manfred Radlwimmer

You should add item which you want to be checked to the ListView's SelectedItems list

foreach(var item in MyListView.Items)
{
    MyListView.SelectedItems.Add(item);
}

I would solve this by using the MVVM pattern. With MVVM you will seperate your business models & logic from the view. When implemented correctly you can modify your data and it will automaticly update the view.

This is a link that contains a walkthrough about how to use it. It also contains an example using the checkbox.

Ok when you check on ALL checkbox all other checkboxes get checked right?

i want to get them checked when ALL checkbox is checked...in the itemsource of the listview i am passing a list of strings..

Tom Droste Over a year ago

I would suggest converting the list of strings to an object that contains a boolean and a string.
