Set the RepositoryItemBaseProgressBar.ShowTitle property to true to display text in the progress bar.
To apply custom formatting to the control’s value, use the RepositoryItem.DisplayFormat property.
To provide a custom display text, handle the RepositoryItem.CustomDisplayText event.
In the code fragment below, a DeleteFiles method removes all files contained within the directory specified by the source parameter. The ProgressBarControl is used to display the progress of file delete operations. The RepositoryItemProgressBar.Minimum and RepositoryItemProgressBar.Maximum properties are used to specify a range for the progress bar that is equivalent to the number of files to be removed. The code also uses the RepositoryItemProgressBar.Step property with the ProgressBarControl.PerformStep method, to increment the position of the progress bar as soon as a file is removed.
