    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();



    My xaml:

    <UserControl.Resources>
     
        <DataTemplate x:Key="dataTemplate">
     
             
                <Canvas  VerticalAlignment="Center"  Margin="10" Height="50"  >
     
                    <TextBlock  Foreground="#FF393838" x:Name="loadingPercentage" VerticalAlignment="Center"  Canvas.Top="16" Text="{Binding WOName}"
                        FontSize="15" />
                    
                    <telerik:RadProgressBar x:Name="pb" Canvas.Top="16" VerticalAlignment="Center" Canvas.Left="100" Width="500" Height="22" Minimum="0" Value="{Binding CurrentValue}"
                    Maximum="100"   />
                     
                    <TextBlock  Canvas.Left="630"  Canvas.Top="16" VerticalAlignment="Center" Foreground="#FF393838" x:Name="tbTotal" Text="{Binding TotalInfo}"
                        FontSize="15" />
                    <Button x:Name="btnViewDetail"  Canvas.Top="16" VerticalAlignment="Center" Tag="{Binding WOId}" Canvas.Left="685"   HorizontalAlignment="Right" Foreground="Black" Content="ViewDetail" Click="btnViewDetail_Click_1" />
     
                </Canvas>
     
            </DataTemplate>
     
     
     
        </UserControl.Resources>
     
     
     
     
            <ListBox Name="lbSaProcess" Grid.Row="1"  ItemTemplate="{StaticResource dataTemplate}" BorderThickness="0" Width="790" Height="750" >
     
      
            </ListBox>

    public class SaWOProcess
       {
           public int WOId { get; set; }

    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.
