Nope. Its not width problem. Its not changing like this always. Its rarely happens. If close the exe and open it again. It works fine.

I cant simulate this error also. Its happening only on client side PC. Its rarely coming. I cant even trace this problem.

Hi Mohan,

As I wrote, I was unable to reproduce this behavior with UltraNumericEditor in version 7.2 of Infragistics for Windows Forms. Actually, I was unable to reproduce this in any version I tested with.

I cannot investigate this without sample reproducing this behavior. To reproduce this, I will need your custom control you have created by inheriting UltraNumericEditor. Also I will need the code of all the events you are handling for your custom control. if I do not have this information or sample reproducing this behavior there is really nothing that I can do for you. There is no way to tell you what is wrong in a control I do not have access to.

So please, try to reproduce this in small sample project and send it to me, or give me all the information about your custom control including:

• Code snippet of your custom UltraNumericEditor implementation;
• Code snippet of any event you are handling for your custom UltraNumericEditor;

Looking forward to your reply.

Yes. we inherited UltraNumericEditor control and added some property to generalise the work among employees. we created it as separate dll. so that others wont know the code behind. they will use that property. but its not much difference than UltraNumericControl. Eg: NumValue property to avoid null. It will return 0 instead.

Hello Mohan,

Thank you for your feedback and code provided.

From the code snippet you sent me it seems that either you have created your own control inheriting UltraNumericEditor or this is not UltraNumericEditor. From all the properties you are setting on the control these ones are not part of UltraNumericEditor in version 7.2 of Infragistics for Windows Froms:

• AllowNegative;
• AllowNull;
• AutoSelect;
• AutoTab;
• EditBackColor;
• EditBackColorReq;
• HelpClickedStatus;
• HelpMultiSelect;
• Max – there is MaxValue property in UltraNumericEditor, but not Max property;
• Min – there is MinValue property in UltraNumericEditor, but not Min property;
• NeedHelp;
• NumValue – there is Value property in UltraNumericEditor, but not NumValue property;
• Range – this is probably your custom enumeration, as it should equals to TMControls.TMNumber.EnumRange.vnByte;
• SuppressZero;
• ToolTipText;
• ValidEntry;
• ValueModified;
• vText;

If you are using control which inherits from Infragistics UltraNumericEditor please send me sample with this custom control so I can check this behavior. Note, that without such sample there is not much I can do.

Thank you for using Infragistics controls.

Its UltraNumericEditor Control. Infragistics version : NetAdvantage for .NET 2007 Vol. 2 CLR 2.0.. Its seems like V7.2.

Hello Mohan,

Thank you for your feedback and video provided.

Now I know what the issue you are facing is. However, I was unable to reproduce this at my side. Also, I was unable to find any similar issue reported in past. In order to investigate this further I should be able to reproduce it at my side. So, can you try to reproduce this in small sample project and send this project to me.

Also, if you are not able to create such sample project, please send me information about:

1. What is the control you are facing this issue with? Form the video you sent me it seems that this is some type of UltraNumericEditor or UltraTextEditor. Please specify the exact control. I know you said you face this in number control, but we do not have such control. I need exact name of the control!
2. Which version of Infragistics for Windows Forms are you using? Please give me the exact specific version you are using. It should be something like 16.2.20162.1000.
3. Send me the code behind. I need both the code generated in Designer file for this numeric control as well as the code from each event handler related to this control.
4. What is the operating system where you are facing this issue?

Looking forward to your reply.
