Gets or sets the minimum value of the progress range.
Namespace : DevExpress.XtraEditors.Repository
Assembly : DevExpress.XtraEditors.v25.2.dll
NuGet Package : DevExpress.Win.Navigation
[DefaultValue(0)]

public int Minimum { get; set; }

Public Property Minimum As Integer
| Type | Default | Description |
|---|---|---|
| Int32 | 0 |
The minimum value.
|
The Minimum property specifies the lowest possible value of the ProgressBarControl. The current progress value (ProgressBarControl.Position property) must be greater than or equal to Minimum.
progressBarControl.Properties.Minimum = 0;
progressBarControl.Properties.Maximum = 100;
progressBarControl.Position = 25;
Note
Setting the Minimum property to a value greater than the Maximum property, automatically sets Minimum to match Maximum. This ensures the progress range remains valid.
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.
using System.IO;
using DevExpress.XtraEditors.Controls;
// ...
private void DeleteFiles(string source){
if (Directory.Exists(source)){
string[] fileEntries = Directory.GetFiles(source);
// Initializing progress bar properties
progressBarControl1.Properties.Step = 1;
progressBarControl1.Properties.PercentView = true;
progressBarControl1.Properties.Maximum = fileEntries.Length;
progressBarControl1.Properties.Minimum = 0;
// Removing the list of files found in the specified directory
foreach(string fileName in fileEntries){
File.Delete(fileName);
progressBarControl1.PerformStep();
progressBarControl1.Update();
}
}
}
// ...
DeleteFiles("d:\\Temp");
