WPF Resize Grid Row when selected - wpf

Question

I have a data template that contains a grid. I would like to make the selected row of the grid larger (height-wise) when the user selects the row. Each cell in the row contains a rectangle for styling purposes and a textbox for data. I have the following that resizes the row when the user clicks on the rectangle, but not when they click inside the text box (which is where they are likely to click). How can I make the row resize when the user clicks in the textbox?
