This dialog is used to find a column in a grid by selecting its name from a dropdown list. This is useful when there are a great number of columns in the grid. The dialog is displayed when you right-click on a column heading and select Find column from the context menu.
Note that fields associated with a related object have an asterisk next to their name.
If you select a column with an asterisk, then it is the related object's column which will be found.
