[英]Scroll to bottom of listbox wp7
I have a listbox with more than 20 items.我有一个包含 20 多个项目的列表框。 How I can scroll to bottom of it?我如何滚动到它的底部? I tried the ScrollIntoView
method, but no success:我尝试了ScrollIntoView
方法,但没有成功:
listmy.SelectedIndex = listmy.Items.Count;// listmy.Items.Count - 1;
listmy.ScrollIntoView(listmy.SelectedIndex);
listmy.UpdateLayout();
The ScrollIntoView method expects an object (the item to scroll to), but you are passing in the numeric index of the selected item. ScrollIntoView方法需要一个 object(要滚动到的项目),但您传入的是所选项目的数字索引。 This will work:这将起作用:
void MainPage_Loaded(object sender, RoutedEventArgs e)
{
listmy.SelectedIndex = listmy.Items.Count - 1;
listmy.ScrollIntoView(listmy.SelectedItem);
}
Call UpdateLayout before ScrollIntoView在 ScrollIntoView 之前调用 UpdateLayout
var item = listmy.Items[listmy.Items.Count - 1];
listmy.UpdateLayout();
listmy.ScrollIntoView(item);
listmy.UpdateLayout();
