privatevoidButton_Click(objectsender,EventArgse){//listbox1.Focus();//inti=listbox1.SelectedIndex;////DataRowdr=ListBox.SelectedItemasDataRow;//////stringselectedText=dr["字段"].ToString();//MessageBox.Show(Convert.ToString(i));listbox1.AddHandler(Grid.MouseDownEvent,newRoutedEventHandler(Grid_MouseDown1),true);}privatevoidGrid_MouseDown1(objectsender,RoutedEventArgse){//MessageBox.Show("listbox被点击");inti=listbox1.SelectedIndex;MessageBox.Show(Convert.ToString(i));}
解决方案
解决方案二：
应该获取Button的父控件ListBoxItem，使用类似：this.list.ItemContainerGenerator.IndexFromContainer();
来获取index值。
