How i can change the maximum property when i use the server side progressbar
example? I create a recordset in the runtask method, and makes a for each loop. I know the
number of record only in this method, so want set a correct maximum value. But the control doesn't refresh the value.

Can you add a new function setMaxium to the Client API for the ProgressBar Object.
So i can add a Client Script to my page where correct the value.

Or have you another solution?

Here my example page:

ASPX:

Code: HTML/ASPX 
<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Test.aspx.vb" Inherits="Test" Debug="true" %>
<%@ Register Assembly="EO.Web" Namespace="EO.Web" TagPrefix="eo" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>My TestPage</title>
    
   
</head>
<body>
    <form id="form1" runat="server">
    <div>
         <eo:ProgressBar ID="ProgressBar1" runat="server" BackgroundImage="00060101"
            BackgroundImageLeft="00060102" BackgroundImageRight="00060103" ControlSkinID="None"
            IndicatorImage="00060104" IndicatorIncrement="7" ShowPercentage="True" StartTaskButton="Button1"
            Value="30" Width="250px">
        </eo:ProgressBar>
    </div>
        <asp:Button ID="Button1" runat="server" Text="Button" />
    </form>
</body>
</html>


VBS Code

Code: Visual Basic.NET 
Partial Class Test
    Inherits System.Web.UI.Page



    Protected Sub ProgressBar1_RunTask(ByVal sender As Object, ByVal e As EO.Web.ProgressTaskEventArgs) Handles ProgressBar1.RunTask
        ProgressBar1.Maximum = 150

        Dim i As Integer
        For i = 0 To 150
            'Stop the task as soon as we can if the user has
            'stopped it from the client side
            If e.IsStopped Then
                Exit For
            End If

            'Here we call Thread.Sleep just for demonstration
            'purpose. You should replace this with code that
            'performs your long running task.
            System.Threading.Thread.Sleep(100)

            'You should frequently call UpdateProgress in order
            'to notify the client about the current progress
            e.UpdateProgress(i)
        Next i

    End Sub


End Class

Hi,

You won't be able to do that. The only thing you can do in RunTask is to update the progess. In fact you rarely need to change the maximum value. Just prorate the progress value based on the maximum value. For example, you can always set the max value to 100 and then call UpdteProgress based on the correct percentage value.

Thanks
