The following code example uses a ProgressBar control to display the progress of a file copy operation. The example uses the Minimum and Maximum properties to specify a range for the ProgressBar that is equivalent to the number of files to copy.
The code also uses the Step property with the PerformStep method to increment the value of the ProgressBar as a file is copied. This example requires that you have a ProgressBar control created called pBar1 that is created within a Form and that there is a method created called CopyFile that returns a Boolean value indicating the file copy operation was completed successfully that performs the file copy operation.
The code also requires that an array of strings containing the files to copy is created and passed to the CopyWithProgress method defined in the example and that the method is called from another method or event in the Form. A ProgressBar control visually indicates the progress of a lengthy operation in one of three styles:. A block that scrolls across a ProgressBar in a marquee fashion.
The Style property determines the style of ProgressBar that is displayed. Note that the ProgressBar control can only be oriented horizontally. For an example of how to create a vertically oriented ProgressBar , see the ProgressBarRenderer class. The ProgressBar control is typically used when an application performs tasks such as copying files or printing documents.
Users of an application might consider an application unresponsive if there is no visual cue. By using the ProgressBar in your application, you alert the user that the application is performing a lengthy task and that the application is still responding.
The Maximum and Minimum properties define the range of values to represent the progress of a task. The Minimum property is typically set to a value of 0, and the Maximum property is typically set to a value indicating the completion of a task. For example, to properly display the progress when copying a group of files, the Maximum property could be set to the total number of files to be copied. The Value property represents the progress that the application has made toward completing the operation.
The value displayed by the ProgressBar only approximates the current value of the Value property. Based on the size of the ProgressBar , the Value property determines when to display the next block or increase the size of the bar. There are a number of ways to modify the value displayed by the ProgressBar other than changing the Value property directly.
You can use the Step property to specify a specific value to increment the Value property by, and then call the PerformStep method to increment the value. To vary the increment value, you can use the Increment method and specify a value with which to increment the Value property. Initializes a new instance of the ProgressBar class.

Open the App. Next, add the following XMLNS declaration at the top element — this is important as it tells the parser to look in your project for the code you added above. Now, go into the Resources section of the file and add this style you can also download as PerformanceProgressBarStyle.
Now, whenever you or your designers place a ProgressBar in your app, set the style to be PerformanceProgressBar and it will be picked up from the App. When people started seeing poor performance on applications that were using indeterminate progress bars, it was a stumper.
I jumped in and started looking at the root of the potential performance problem. It was definitely interesting because the emulator experience was pretty good though still heavy in the UI thread , but once these same apps were on real developer devices, the issue manifested.
The emulator is just that — it emulates , so there will be differences. Working to unpeel the onion and diagnose the indeterminate ProgressBar as the root of the performance issue, some of what was tried:. So there, the issue was in the animations and underlying template for the indeterminate ProgressBar and its use of Slider controls. A consistent and good-looking set of controls is an important part of the platform and so the progress bar has a very slick appearance.
The following code example illustrates how a progress bar can maintain a count of the files in a copy operation. C Progressbar Example Here is my example of using a simple for loop in C.
True to be active, False to be passive. NET application, C add progress bar to Windows Forms applications progress bar in c windows application program. I create a windows application program, I want to place a progress bar in this time. How to use it and how it works. Firstly, I will show you how simple this has become for application developers. In Windows Forms applications progress is typically shown using the standard Animated Progress Indicator in C Windows Some notes about the sample: How to download a file in C progressbar and download speed file in windows application and also i have to show how much it is upload in progress bar , please Here I will explain how to use progressbar control in windows application using c progress bar during postbacks in asp example in asp.
NET 1. BackgroundWorker example. It does this 10 times so we can see how to monitor progress. The image address is provided by the user in a WPF form, and we report the number of files downloaded in a progress bar on that form. Generic; using System. Linq; using System. Net; using System.
