DataGrid Column Focus Out Event

Question

I have an editable datagrid and I'm trying to accomplish the
following:
When a user edits a cell, then focuses out, a function is
called that sends off a service with that value, along with the id
value in that same item. I've tried using itemFocusOut, but I'm
getting bizzare results---the function is executing multiple times.
So i need the function to know what cell was focused out, and also
all of the other information that accompanies that item.
Thanks for any help.

Answer 1

Here's what I ended up doing.
Somewhere after Load, I added:
PropertyDescriptor pd = DependencyPropertyDescriptor.FromProperty(DataGridColumn.ActualWidthProperty, typeof(DataGridColumn));
foreach (DataGridColumn column in Columns) {
//Add a listener for this column's width
pd.AddValueChanged(column, new EventHandler(ColumnWidthPropertyChanged));
Then the following 2 methods:
private bool _columnWidthChanging;
private void ColumnWidthPropertyChanged(object sender, EventArgs e)
// listen for when the mouse is released
_columnWidthChanging = true;
if (sender != null)
Mouse.AddPreviewMouseUpHandler(this, BaseDataGrid_MouseLeftButtonUp);
void BaseDataGrid_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
if (_columnWidthChanging) {
_columnWidthChanging = false;
/// whatever you wanted to do here
The ColumnWidthPropertyChanged fires constantly while the user drags the width around, so if you just listen to that, you'll be over-doing it.
Adding the PreviewMouseUp handler let me only do my processing when the user is done changing the width.
Hope this helps someone.
