Hi - thanks for your response.

It's kind of complicated, but I'll do my best to explain.

Our UI starts out with a list view, and when you click on a record, we shrink down the list view to one or two columns on the left with the detail showing in another pane on the right. When the user mouses over the left hand list view in this split mode we gray out the detail pane on the right and  want to effectively show the rest of the mouseover record. What I've done is create another xamWebGrid in the right hand pane that shows the remainder of the columns for the row the user is mousing over in the left hand side... make sense?

Another strategy I tried was to do something like this, but it fails with a null reference error

            UIElement x = this.xamGrid.Rows[0].Cells[0].Content as UIElement;

            x.MouseEnter += new MouseEventHandler(x_MouseEnter);

Ah, sorry, should have been more, clear. You should be able to  pass in the the xamWebGrid to the FindElementsInHostCoordinates method and into e.GetPosition.

And so is _panel the container of the xamWebGrid and the point object build off the location of the xamWebGrid's container? 

 private void xamGrid_MouseMove(object sender, MouseEventArgs e) {

Point position = e.GetPosition(GridContainer);

}

Steve,

That should do it. I really appreciate your help. Thanks so much.

Hi Greg, 

That article is pretty old, as the UIElement.HitTest method does not exist in Silverlight.  Instead, you can use the VisualTreeHelper.FindElementsInHostCoordinates

IEnumerable<UIElement> elements = VisualTreeHelper.FindElementsInHostCoordinates(new Point(x, y), this._panel);

CellsPanel cellsPanel = null;

foreach (UIElement elem in elements)

{

cellsPanel = elem as CellsPanel;

if (cellsPanel != null)

break;

} 

In the code above, a CellsPanel represents a Row's control. And it has a Row property associated with it.  If you need a Cell, then look for a CellControl. 

Hope this helps,
