myloonatic Posted September 5, 2007 Report Share Posted September 5, 2007 i coded my application to load the chart dynamically (i didn't drag and drop a chartfx chart component into my design page) but when it run, the scrollposition which is suppose to appear in the most right side didn't function as expected. i suspect it was something related to the way i render because when i render in .net , scrollposition malfunction. but when i omitted the render mode, scrollposition appears to be at the most right hand side, good news though but another problem occur which is the scrollbar cannot be scroll. once i click to scroll , error "ICallBackEventHandler not implemented" appear. can anyone help me with this ? below is my code: Private Sub LoadChart(ByVal strTestcell As String) Dim strCompletePath As String Dim strBinNo As String = "Overall1.mex" Dim chartGenerate As New ChartFX.WebForms.Chart m_strRootPath = Application("ChartFolderPath") strCompletePath = m_strRootPath & m_strDatePath & "\" & strTestcell & "\" & strBinNo Try If File.Exists(strCompletePath) Then chartGenerate.Import(FileFormat.Binary, strCompletePath) chartGenerate.Width = 1000% chartGenerate.Height = 450 If Me.chkEnableScrollbar.Checked = True Then chartGenerate.AxisX.AutoScroll = True chartGenerate.AxisX.PixelsPerUnit = 43 chartGenerate.AxisX.ScrollPosition = chartGenerate.AxisX.ScrollSize Else chartGenerate.AxisX.AutoScroll = False End If chartGenerate.RenderFormat = ".Net" Me.ChartPlaceHolder.Controls.Add(chartGenerate) Response.Write("<vbcrlf>") Else Me.ChartPlaceHolder.Controls.Add(New LiteralControl("<b>Chart For " & strTestcell & " Not Found !</b><br>")) End If Catch ex As Exception Response.Write("Exception Error LoadChart : " & ex.Message) End Try End Sub Quote Link to comment Share on other sites More sharing options...
Frank Posted September 6, 2007 Report Share Posted September 6, 2007 The problem here is this: chartGenerate.Width = 1000% The chart doesn't know its size at in the server and therefore chartGenerate.AxisX.ScrollSize will return a value based on the wrong size.
