.net - why listview scrolliintoview is not working? -


I have a list of items and next I have a button I want functionality like this, when I click on the button I'll show items related to the list view at the top of the list. For this I thought that Screintwe would work, but unfortunately it is not working. Any suggestions?

... lstview.SelectedItem = lstview.Items.GetItemAt (lstview.SelectedIndex); Lstview.ScrollIntoView (lstview.SelectedItem); Lstview.UpdateLayout (); .....

The ScrollIntoView method will only show items, if it appears If it is already visible, then the method will not have any effect from the call. In your case, if you are able to click on the item, then the item is in the view and there is no need to scroll. Explanation.

If the object is not visible, then it is aligned above or below the viewport.

If you always want that item to be the first item in the viewport, you must adjust the vertical offset to get the Y value of your ListBox and scroll the scroll viewer to the Y value. 

  listBoxScrollViewer.ScrollToVerticalOffset (100); // Measure the Y value of your list box

You can get the scrollviewer from ListBox like you.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
