实现:
即将跳转到页面A,在页面A中有一个listbox,在跳转的时候,接收参数,自动选中listbox中的某项
/// <summary>
/// 接收参数,定位当前选中项
/// </summary>
protected override void OnNavigatedTo(System.Windows.Navigation.NavigationEventArgs args)
{
IDictionary<string, string> parameters = this.NavigationContext.QueryString;
if (parameters.ContainsKey("Id"))
{
string id = parameters["Id"];//图片Id
int index = 0;
for (int i = 0; i < imglist1.Items.Count; i++)
{
//ImgInfoBase为listbox的Item项; imglist1.ItemsSource=(List<ImgInfoBase>) ...
ImgInfoBase item = (ImgInfoBase)imglist1.Items[i];
if (item.Id == id)
{
index = i;
break;
}
}
if (imglist1.Items.Count > index)
{
UpdateLayout();
imglist1.SelectedIndex = index;//使listbox滚动到指定的位置项上
//imglist1.ScrollIntoView(imglist1.Items[index]);
}
}
base.OnNavigatedTo(args);
}
