The Watches window lets you view anything from simple variables to complex expressions. The Watches window is often used as a complement to the Local/Global Variables windows. You can add variables/expressions that you wish to track over the course of the debugging session, or that you wish to find quickly without having to sort through a bigger list in the Local/Global Variables windows.
Displays the expression or variable name. To edit, select the expression and click in the corresponding Name column.
Displays the value of the expression. If the expression is a variable, the value can be edited by selecting the expression and clicking in the corresponding Value column.
You can add a variable/expression to the watches window by clicking in the Name column of the last empty row, which will open it up for editing, and then type in the name of the variable or the expression and press Enter.
You can also use drag and drop to add watches. Select the desired text from the Code Editor, and drag the text using the mouse to the Watches window and drop it. The selected text will be added to the end of the list of watches.
Watches can also be added from the Local / Global Variables window as well as the Database Tables window. Select the specified variable/table column, right-click and select Add to Watches.
