RepositoryItemProgressBar.Maximum Property
Gets or sets the maximum value of the progress range.
Namespace: DevExpress.XtraEditors.Repository
Assembly: DevExpress.XtraEditors.v25.1.dll
NuGet Package: DevExpress.Win.Navigation
Declaration
Property Value
| Type | Default | Description |
|---|---|---|
| Int32 | 100 | The maximum value. |
Remarks
The Maximum property specifies the highest possible value of the ProgressBarControl. The current progress value (ProgressBarControl.Position property) must be less than or equal to Maximum.
progressBarControl.Properties.Minimum = 0;
progressBarControl.Properties.Maximum = 100;
progressBarControl.Position = 25;
Note
Setting the Maximum property to a value less than the Minimum property, automatically sets Maximum to match Minimum. This ensures the progress range remains valid.
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.
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");
