Hi guys,

Im using the standard Progress Bar in Silverlight 3. Im returning a dataset using LINQ and then populating a liquid treeview by looping through the returned data.

What i want to do is show the progress of this through a progress bar.

The problem is progress bar only updates (or at least shows it) when the process had finished. Im not seeing the progress as i thought i would.

Here is my code

PlotXMLData = XDocument.Parse(e.Result)

            TreeProgBar.Value = 0

            Dim LettingCount = From i In PlotXMLData...<Letting> Select i.@LettingsID

            TreeProgBar.Maximum = LettingCount.Count

            'Dim Letting As Object

            Dim n As Liquid.Node

            For Each SiteNode As Liquid.Node In LettingsTree.Nodes

                Dim intSiteID As Integer

                intSiteID = SiteNode.ID

                Dim Letting = From i In PlotXMLData...<Letting> Select i.@LettingsID, i.@PlotID, i.@SiteID Where SiteID.ToString = intSiteID.ToString

                For c = 0 To Letting.Count - 1

                    n = New Liquid.Node

                    n.Title = Letting(c).PlotID

                    n.ID = Letting(c).LettingsID

                    SiteNode.Nodes.Add(n)

                    TreeProgBar.Value = TreeProgBar.Value + 1

                    TreeProgBar.UpdateLayout()

                Next

            Next

            LettingsTree.UpdateLayout

Any help would be great. Thanks

Hi,

I imagine to achieve this you would need to use something like a DispatcherTimer and perform 1 operation for each timer tick and update the progress bar there.

Thanks!
