RepositoryItemProgressBar.Minimum Property

Gets or sets the control’s minimum value.

Namespace: DevExpress.XtraEditors.Repository

Assembly: DevExpress.XtraEditors.v24.1.dll

NuGet Package: DevExpress.Win.Navigation

Declaration

C#

[DefaultValue(0)]
[DXCategory("Behavior")]
public int Minimum { get; set; }

VB.NET

<DXCategory("Behavior")>
<DefaultValue(0)>
Public Property Minimum As Integer

Property Value

Type	Default	Description
Int32	0	An integer value representing the minimum value.

Remarks

This property specifies the lower limit for the ProgressBarControl.Position property. When Minimum is modified, the control is immediately redrawn to reflect the new range.

Example

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.

C#

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");

VB.NET

Imports System.IO
Imports DevExpress.XtraEditors.Controls
' ...
Private Sub DeleteFiles(ByVal source As String)
   If Directory.Exists(source) Then
      Dim fileEntries As String() = 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
      For Each fileName As String In fileEntries
         File.Delete(fileName)
         progressBarControl1.PerformStep()
         progressBarControl1.Update()
      Next fileName
   End If
End Sub
' ...
DeleteFiles("d:\Temp")
