Scrolling the datagrid
in [Compact Framework]
|
From: Mesalem on 8 Feb 2005 06:47 I have a datagrid derived class where i want to scroll the horizontal scroll bar to the right. i tried the following code: HScrollBar sb = (HScrollBar)base.GetType().GetField("m_sbHorz", BindingFlags.NonPublic|BindingFlags.GetField|BindingFlags.Instance).GetValue(this); sb.Value=5; but i received a NullReferenceException in System.Windows.Forms.DataGrid.Dll, I tried the following code and the same exception happened HScrollBar sb = (HScrollBar)base.GetType().GetField("m_sbHorz", BindingFlags.NonPublic|BindingFlags.GetField|BindingFlags.Instance).GetValue(this); System.Reflection.PropertyInfo pi=sb.GetType().GetProperty ("Value",BindingFlags.Public | BindingFlags.Instance ); pi.SetValue (sb,90,null); any suggestions??

From: Sergey Bogdanov on 8 Feb 2005 10:21 You may consider EnsureVisible method and if you would like to scroll to the end of the list then call the method with "listView.Items.Count - 1".

From: Mesalem on 9 Feb 2005 04:21 this method will scroll the listview top or down (vertical), what about scrolling to the right or the left (horizonal)??
