Exports.ShowExportDialog causes exception.

[Shengfeng.yao]

I just upgrade the tee chart dll from "Teechart Pro for .Net v1" to "TeeChart for .Net 2010".
An exception occured when the ShowExportDialog invoked.
The exception information as follow:
System.ArgumentOutOfRangeException: Value of '0' is not valid for 'Value'. 'Value' should be between 'Minimum' and 'Maximum'.
Parameter name: Value
at System.Windows.Forms.NumericUpDown.set_Value(Decimal value)
at Steema.TeeChart.Editors.Export.ExportEditor.listBox1_SelectedIndexChanged(Object sender, EventArgs e)
at System.Windows.Forms.ListBox.OnSelectedIndexChanged(EventArgs e)
at System.Windows.Forms.ListBox.set_SelectedIndex(Int32 value)
at Steema.TeeChart.Editors.Export.ExportEditor.SetTabs()

at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)
at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam)

Is there any special setting for the "ShowExportDialog" in new interface?

Hello Shengfeng.yao,

When I use following line of code in last version:

Code: Select all

 tChart1.Export.ShowExportDialog();

It works fine for me. Please try to arrange a simple project for us, so we can try to help you to solve your problem.

Thanks,

Hi Sandra,
In my souce code, I defined a commander class wich inherit from teechart.commander.
The code for 'Print Button' (btnPrint) is similar with 'Save Button' (btnSave).
When run the program, code for 'Print Button' works well, but the 'Save Button', the error message displayed.

Any comments will be very appreciated.
Best Regards,

The source code as below:

public class CommanderEx : Steema.TeeChart.Commander, Steema.TeeChart.ITeeEventListener
{
//In this class, handle the click event
protected override void OnButtonClick(System.Windows.Forms.ToolBarButtonClickEventArgs e)
{
//other process....

HandleTBButtonClick(this, e);
}
}

public void HandleTBButtonClick(object sender, System.Windows.Forms.ToolBarButtonClickEventArgs e)
{
// Evaluate the Button property to determine which button was clicked.
switch ((TBButtons)((System.Windows.Forms.ToolBar)_toolBar).Buttons.IndexOf(e.Button))
{
case TBButtons.btn3D:
{
break;
}
case TBButtons.btnEdit:
{

break;
}
case TBButtons.btnCopy:
{

break;
}
case TBButtons.btnPrint: //This works well
{
try
{
if (this.ViewCollection.SelectedDistributionViews.Count == 1)
{
EnsureToolbarSelectedChart();

_toolBar.Chart.Chart.Printer.Preview();
}
}
catch (Exception ex)
{
Debug.WriteLine(ex.ToString());
}
break;
}
case TBButtons.btnSave:
{
try
{
if (this.ViewCollection.SelectedDistributionViews.Count == 1)
{
EnsureToolbarSelectedChart();
_toolBar.Chart.Chart.Export.ShowExportDialog(); //error message displayed,but the exception not caught.
}
}
catch (Exception ex)
{
Debug.WriteLine(ex.ToString());
}
break;
}
case TBButtons.btnFocused:
{

break;
}
case TBButtons.btnViewChart:
{

break;
}
case TBButtons.btnViewTable:
{

break;
}
case TBButtons.btnViewPercent:
{

break;
}

case TBButtons.btnConfig:
{
this.Cursor = Cursors.WaitCursor;

// Show the configuration form
this.ShowConfigForm();
this.Cursor = Cursors.Default;
break;
}
case TBButtons.btnDelete:
{
if (_mnuDeleteSelected.Visible == true)
{
this.HandleDelete(true);
}
else
{
this.HandleDelete(false);
}

break;
}
}

}
catch (Exception ex)
{
Trace.Instance.TraceException(ex, true);
MessageBox.Show("Error in Distributions: " + ex.ToString());
Debug.WriteLine(string.Format("HandleTBButtonClick : caught an exception {0}", ex.ToString()));
this.Cursor = Cursors.Default;
}
}
