RadProgressBar and waiting status

[Mirko]

Hello,

    I'm developing an application for my company. I use a radprogressbar and a radstatusstrip into an user control, that is inside a radribbonform. I use those control as waiting status in some operation.
I tried backgroundworker and timer but the progressbar after the operation finish. Also i use statusstrip.Refresh() but it doesn't work.

Please help me. !!!!

Hello Mirko,

Here is a simple implementation of using a separate thread to update a progress bar and status bar on a user control.

Main Form:

    public delegate void DelegateTickProgress();

    public partial class Form1 : Form
    {
        public DelegateTickProgress _delegateTickProgress;
        Thread _workerThread;

        public Form1()
        {
            InitializeComponent();
            _delegateTickProgress = new DelegateTickProgress(this.TickProgress);
        }

        private void radButton1_Click(object sender, EventArgs e)
        {
            statusUserControl1.ResetStatus();
            _workerThread = new Thread(new ThreadStart(this.WorkerThreadFunction));
            _workerThread.Start();
        }

        private void WorkerThreadFunction()
        {
            for (int i = 0; i < 10; i++)
            {
                Thread.Sleep(100);
                this.Invoke(this._delegateTickProgress);
            }
        }

        private void TickProgress()
        {
            statusUserControl1.UpdateStatus();
        }
    }

User Control:

    public partial class StatusUserControl : UserControl
    {
        public StatusUserControl()
        {
            InitializeComponent();
        }

        public void ResetStatus()
        {
            radProgressBar1.Value1 = 0;
        }

        public void UpdateStatus()
        {
            radProgressBar1.ProgressBarElement.PerformStepValue1();
            radLabelElement1.Text = radProgressBar1.Value1.ToString();
        }
    }

The WorkerThread function is where you should perform any time consuming operations.

I hope this helps.

Hi Robert,
    Thanks for your help but in my case it doesn't work.
My code are :

 

	delegate void setProgessBarCallback();
	private System.Timers.Timer m_timer;
	setProgessBarCallback _setProgessBarCallback ;
	MyUC()
	{
	InitializeComponent();
	m_timer = new System.Timers.Timer();
	m_timer.AutoReset = true;
	m_timer.Interval = 1000;
	m_timer.Elapsed += new System.Timers.ElapsedEventHandler(m_timer_Elapsed);
	_setProgessBarCallback = new setProgessBarCallback(setProgessBar);
	}
	void MyFunction()
	{
	StartProgressBar();
	//Do something
	StopProgressBar();
	}
	void StartProgressBar()
	{
	m_timer.Start();
	}
	void m_timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
	{
	this.Invoke(_setProgessBarCallback);
	}
	private void setProgessBar()
	{
	this.radProgressBarElement1.PerformStepValue1();
	if (this.radProgressBarElement1.Value1 >= this.radProgressBarElement1.Maximum)
	this.radProgressBarElement1.Value1 = this.radProgressBarElement1.Minimum;
	this.radProgressBarElement1.Text = this.radProgressBarElement1.Value1.ToString();
	//this.radStatusStrip1.Refresh();
	//this.radStatusStrip1.RepaintElements(radProgressBarElement1);
	//Application.DoEvents();
	}

Any suggestions?
