向 Datagrid 添加新行时如何关注特定单元格？

Question

When using Silverlight/WPF Datagrid and you add a new row to the existing collection, how can I jump into a specific cell's edit mode in order to hint to the user that this field needs to be filled out right away?

Many Thanks,

Answer 1

This is how I was able to make it work in SL 5 RC.

dg.ItemsSource.Add(data);
dg.SelectedItem = data;                  //set SelectedItem to the new object
dg.ScrollIntoView(data, dg.Columns[0]);  //scroll row into view, for long lists, setting it to start with the first column
dg.Focus();                              //required in my case because contextmenu click was not setting focus back to datagrid
dg.BeginEdit();                          //this starts the edit, this works because we set SelectedItem above

Hope this helps.

In Silverlight 4 it is:

dg.SelectedItem = data;
dg.CurrentColumn = dg.Columns[1]; // You have to use this line instead
dg.Focus();
dg.BeginEdit();
