Progressvalue value is 0 but still show full status

[cde]

dear all,
 I  run into problem with progressbar .  some time gave progressbar value 0, but it show full progress status. following is code :

var wolist = Newtonsoft.Json.JsonConvert.DeserializeObject<List<workorder>>(e2.Result);

                  

                 

                  List<SaWOProcess> list = new List<SaWOProcess>();

                  lbSaProcess.ItemsSource = null;

                  foreach (var item in wolist)

                  {

                      double v = 0.0;

                      double qty = item.Qty ?? 0.0;

 

                      if (item.CompletedQty != null)

                      {

                          v = (double)item.CompletedQty / (double)item.Qty * 100.0;

                      }

                        

 

                      list.Add(new SaWOProcess() { Qty = qty, WOId = item.Id, WOName = item.WOName, CurrentValue = Convert.ToInt32(v)  , TotalInfo = string.Format("{0}/{1}", item.CompletedQty, qty) });

                        

                      

                  }

          

                  lbSaProcess.ItemsSource = list;

 

                  lbSaProcess.UpdateLayout();

<UserControl.Resources>

    <DataTemplate x:Key="dataTemplate">

Hi cde,

 Please make sure the CurrentValue is bound two-way:

Value="{Binding CurrentValue, Mode=TwoWay}"

and your ViewModel implements INotifyPropertyChanged:

public int  CurrentValue
 {
         get
         {
             return this.currVal;
         }
         set
         {
             if (this.currVal != value)
             {
                 this.currval = value;
                 this.OnPropertyChanged("CurrentValue");
             }
         }
}

Let us know if this helps you proceed further.
