Hi,

I hope i'm in correct subforum, i can't find one for progressarea and manager.

I've an issue with the ProgressArea control, as first i will describe the scenario:
At page default.aspx we have toolbar and grid. The grid displays list with all XML files available from a folder. After choosing a XML file, RadWindow will be displayed. In this window we will read the XML and process all contents into database. This take some time to complete, so we will display progressarea control to show the status to user. This works very well at first time but after second or third or fourth time the progressarea will not shown.

The progressarea showns with postback only, so we're forcing a postback when the window loads first time.
The code below is a stripped version. The progress will take more than 1 minute. The progress will reach 100 percent.

RadWindow:

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

<script language="javascript" type="text/javascript">

function StartSync(sender, args) {

sender.click();

}

</script>

</head>

<body>

<form id="frm" runat="server">

<div style="display: none">

<telerik:RadButton ID="cmdSync" runat="server" OnClientLoad="StartSync" />

</div>

<div style="padding-top: 10px;">

<telerik:RadScriptManager id="ScriptManager1" runat="server" />

<telerik:RadProgressManager id="radProcessMan" runat="server" />

<telerik:RadProgressArea id="radProcessArea" runat="server" Width="375px" SkinID="radProcArea">

<Localization CurrentFileName="Koppelen:" UploadedFiles="Status:" />

<ProgressTemplate>

<ul class="ruProgress" style="background-image: none; padding-top: 10px;">

<li class="ruFileCount">

<div id="SecondaryProgressBarOuterDiv" class="ruBar" runat="server">

<div id="SecondaryProgressBarInnerDiv" runat="server">

</div>

Status: <span id="SecondaryPercent" runat="server"></span>% (<span id="SecondaryValue" runat="server"></span>)

</li>

<li class="ruCurrentFile" style="font-size: 12px;">

Bestand: <br />

<div style="height: 30px; overflow: hidden;">

<b><span id="CurrentOperation" runat="server" style="font-size: 12px"></span></b>

</div>

</li>

</ul>

</ProgressTemplate>

</telerik:RadProgressArea>

</div>

</form>

</body>

</html>

Codebehing RadWindow:

Imports Telerik.Web.UI

Partial Class frmSync

Inherits System.Web.UI.Page

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

If Not Page.IsPostBack Then

radProcessArea.ProgressIndicators = Upload.ProgressIndicators.CurrentFileName Or _

Upload.ProgressIndicators.FilesCount Or _

Upload.ProgressIndicators.FilesCountBar Or _

Upload.ProgressIndicators.FilesCountPercent

End If

End Sub

Protected Sub cmdSync_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles cmdSync.Click

doSync()

ClientScript.RegisterClientScriptBlock(GetType(Page), "CloseWindow", "GetRadWindow().close()", True)

End Sub

Private Sub doSync()

Dim counter As Integer

Dim i As Integer

Dim strFileName As String

'set progress to zero

UpdateProgress(0, "adressen verwerken...", 0, 0)

Try

strFileName = "c:\temp\xmlfile.xml"

If File.Exists(strFileName) Then

xmldoc = New XmlDocument

xmldoc.Load(strFileName)

counter = xmldoc.SelectNodes("/nodes").Count

i = 0

Dim xmlNode As XmlNode

For Each xmlNode In xmldoc.SelectNodes("/nodes")

'Process each node

'update progressbar

UpdateProgress(CInt(i / (counter / 100)), "", counter, i)

i += 1

Next

End If

Catch ex As Exception

exceptions.log.Publish(ex)

Finally

xmldoc = Nothing

End Try

End Sub

Private Sub UpdateProgress(ByVal intPercent As Integer, ByVal strMessage As String, ByVal intCount As Integer, ByVal intCurrent As Integer)

Dim radProgress As RadProgressContext

Try

radProgress = RadProgressContext.Current

radProgress.SecondaryPercent = intPercent

radProgress.SecondaryTotal = 100

radProgress.SecondaryValue = String.Format("adres {0} van {1} adressen", intCurrent, intCount)

radProgress.CurrentOperationText = strMessage

Catch ex As Exception

exceptions.log.Publish(ex)

End Try

End Sub
