I would prefer to use the normal WPF-CkeckBox in a ColumnTemplate. Then simple bind the CheckBox to your ItemSource and go throught it.
我更喜欢在 ColumnTemplate 中使用普通的 WPF-CkeckBox。然后简单地将 CheckBox 绑定到您的 ItemSource 并通过它。
<DataGridTemplateColumn Header="Ist aktiv" IsReadOnly="True">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<CheckBox IsChecked="{Binding IsActiveBool}" Click="myIsActiveCheckBox_Click" />
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

On button click event
按钮点击事件
static int SelectColumnIndex = 0;
PerformAction_Click(object sender, System.EventArgs e)
{
string data = string.Empty;
foreach(DataGridViewRow row in MyDataGridView.Rows)
{
if(row.Cells[SelectColumnIndex].Value!=null &&
Convert.ToBoolean(row.Cells[SelectColumnIndex].Value) == true)
{
foreach(DataGridViewCell cell in row.Cells)
{
if(cell.OwningColumn.Index!= SelectColumnIndex)
{
data+= (cell.Value + " ") ; // do some thing
}
