Using DevExpress, you can enhance your application's user experience by adding a custom wait form to indicate progress during lengthy operations. Below, we’ll walk through creating and using a custom wait form (frmWaitForm
) in a Windows Forms application.
How to use SplashScreenManager in C#?
Open Visual Studio, then click New Project, then select Visual C# on the left, then Windows and then select Windows Forms Application. Name your project "ProgressIndicatorExample" and then click OK
Design your form as shown below.
frmWaitForm
Form1
The frmWaitForm
inherits from DevExpress.XtraWaitForm.WaitForm
and is the central component for displaying progress messages. The code below demonstrates how to customize this form.
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using DevExpress.XtraWaitForm; namespace ProgressIndicatorExample { public partial class frmWaitForm : WaitForm { public frmWaitForm() { InitializeComponent(); this.progressPanel1.AutoHeight = true; } #region Overrides public override void SetCaption(string caption) { // Set the caption text dynamically base.SetCaption(caption); this.progressPanel1.Caption = caption; } public override void SetDescription(string description) { // Set the description text dynamically base.SetDescription(description); this.progressPanel1.Description = description; } public override void ProcessCommand(Enum cmd, object arg) { base.ProcessCommand(cmd, arg); } #endregion public enum WaitFormCommand { } } }
In your main form, you can display the wait form during a long-running operation. The following example shows how to integrate the frmWaitForm
using a button click event.
private void simpleButton1_Click(object sender, EventArgs e) { // Show the wait form SplashScreenManager.ShowForm(this, typeof(frmWaitForm), true, true, false); // Update wait form caption SplashScreenManager.Default.SetWaitFormCaption("Processing data..."); // Simulate a lengthy operation for (int i = 0; i < 100; i++) { //Add your code here Thread.Sleep(10);//Only for demo } // Close the wait form SplashScreenManager.CloseForm(); }
Use SplashScreenManager.ShowForm
to display frmWaitForm
.
Use SplashScreenManager.CloseForm
to ensure the wait form is closed once the operation completes.
By combining the custom wait form frmWaitForm
with the SplashScreenManager
, you can create an elegant progress indicator for your DevExpress-based Windows Forms applications.
