[英]WPF C# Get text from a Textblock inside a ListBoxItem
如何訪問ListBoxItem內Stackpanel內的Textblock?
例如:
ListBoxItem MyItem = new ListBoxItem();
StackPanel StackPnl = new StackPanel();
TextBlock Title = new TextBlock();
Title.Text = "Item 1";
StackPnl.Children.Add(Title);
MyItem.Content = StackPnl;
以后如何使用Listbox.SelectedItem訪問該Textblock的Text屬性?
嘗試這個:
//listBox1 is your ListBox
ListBoxItem MyItem = listBox1.SelectedItem as ListBoxItem;
if(MyItem != null)
{
StackPanel sp = MyItem.Content as StackPanel;
if(sp != null && sp.Children.Count > 0)
{
TextBlock textBlock = sp.Children[0] as TextBlock;
if(textBlock != null)
{
string text = textBlock.Text;
}
}
}
