This property specifies the lower limit of the ProgressBar.Value property. When the value of the ProgressBar.Minimum property is changed, the System.Windows.Forms.ProgressBar control is redrawn to reflect the new range of the control. When the value of the ProgressBar.Value property is equal to the value of the ProgressBar.Minimum property, the progress bar is empty. To change the value of the progress bar, use the ProgressBar.Step property with the ProgressBar.PerformStep method, use the ProgressBar.Increment(int) method, or set the value of the ProgressBar.Value property directly.
