Question

I have a grid and I need to dynamically replace a control that resides in one of the cells. I don’t know in terms of syntax to pinpoint the grid cell, as where do I put in the row and column number so I can delete whatever is in it.

Answer 1

If you know the cell and row that the control lives in, you can use a LINQ statement to grab it.

Here’s a LINQ statement that will get the first control that is in column 3, row 4.

var control = (from d in grid.Children
               where Grid.GetColumn(d as FrameworkElement) == 3 
                  && Grid.GetRow(d as FrameworkElement) == 4
               select d).FirstOrDefault();
