  [activereports_archive]Hi
  
  I have a problem with CustomControl in SectionReport. The exception appears on PrintPreview and in Designer, if I set Height\Width from 0.01 to 0 in ActiveReport7 and ActiveReport9. Could you fix this bug?
  
  Thanks

  Code example:
  
  [csharp] CustomControl customControl = new CustomControl(typeof(System.Windows.Forms.TextBox));
  
  customControl.ImageType = ImageTypes.PNG;
  
  customControl.Width = 10;
  
  customControl.Height = 0.01f;
  
  detail.Controls.Add(customControl);[/csharp]

  On PrintPreview an exception appears:
  
  Parameter is not valid.

  [activereports_archive]The error most likely occurs because you’re using the System.Windows.Forms.TextBox control. The Height property of the TextBox is of type Int32 which might be causing the error.
  
  I would suggest you to try using GrapeCity.ActiveReports.SectionReportModel.TextBox instead of the MS TextBox, which does not cause an error.

  [csharp]CustomControl customControl = new CustomControl(typeof(GrapeCity.ActiveReports.SectionReportModel.TextBox));
  
  customControl.ImageType = ImageTypes.PNG;
  
  customControl.Width = 10;
  
  customControl.Height = 0.01f;
  
  rpt.Sections[“detail”].Controls.Add(customControl);[/csharp]

  If this does not meet your requirement, could you tell the purpose of setting the height to such a small value and the purpose of using the TextBox control.

  Thanks[/activereports_archive]

  [activereports_archive]System.Windows.Forms.TextBox is an example and it doesn’t matter.
  
  Why such a small value? Because the user can input such value in a designer and crashes the application.
  
  The exception occurs in CustomControl before calling Control.Paint function, so I can’t impact on it. Could you not print CustomControl if size is too small for Bitmap?

  Note. If TextBox has zero Height\Width no exceptions occurs.

  [activereports_archive]Let me get in touch with the development team on this and get back to you. I would like to inform that if found to be a bug, the fix would be available in the latest version as ActiveReports 7 is no longer in development. Tracking id - 219652[/activereports_archive]

  The issue you were facing was fixed in AR10 SP2 which can be downloaded from - http://cdn.grapecity.com/ActiveReports/ar10/hotfixes/ActiveReports-v10.2.8627.0.msi

  You could also download the latest version i.e AR12 instead of AR10, which also has the fix -
