CheckBox Checked and Un-Checked Events in Data Grid Header

<CheckBox Name="chkDiscontinue" IsChecked="{Binding values,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" />

</DataTemplate>

</DataGridTemplateColumn.CellTemplate>

</DataGridTemplateColumn>

</DataGrid.Columns>

</DataGrid>

There are two events that take place in a Data Grid Header, namely checked event and unchecked event. I will explain both events one by one as shown below.

1. Check Box Checked Event in Data Grid Header Select Column

In this event, when you check the check box in the Data Grid header Select column then all the check boxes present in cells of that column will be in a checked state. See the following snapshot:



The code behind for the Check Box Checked Event in the Data Grid Header Select Column is:

private void CheckBox_Checked(object sender, RoutedEventArgs e)

{

Database DB = new Database();

Products products = new Products();

foreach (var r in DB.prod)

{

r.values = true;

}

DB.SaveChanges();

dataGrid1.ItemsSource = DB.prod.ToList();

}

2. Check Box Un-Checked Event in Data Grid Header Select Column

In this event when you un-check the check box in the Data Grid header Select column then all the check boxes present in the cells of that select column will be in the un-checked state. See the following snapshot:



The code behind for the Check Box Un-Checked Event in the Data Grid Header Column is:

private void CheckBox_Unchecked(object sender, RoutedEventArgs e)

{

Database DB = new Database();

Products products = new Products();

foreach (var r in DB.prod)

{

r.values = false;

}

DB.SaveChanges();

dataGrid1.ItemsSource = DB.prod.ToList();

}
