Would you have any idea, why this is happening, we have just one
worksheet with one column and are trying to do an autofit on that.

Hi,

Please download and use the latest version: Aspose.Cells for .NET v7.2.0.2

If you still find the issue, kindly give us your template file and sample code to reproduce the issue on our end. We will check your issue soon.

Thank you.

Hi,
I have used the latest version and can still see this error happening.

There is no template file that i can provide, but this is happening when we try to use the autofitcolumn as can be seen from the debug trace.

It is happening when we call worksheet.AutoFitColumn(columnID)

I have provided you with the internal aspose debug trace and was expecting the developer to be able to figure out where exactly this error is coming from.
This is escalating into a very serious issue for our customers and we need to get this resolved soon. I would really appreciate if we get a speedy solution to this issue.

thanks,
Jaideep.

Hi,

Please download and try the latest version:
Aspose.Cells
for .NET v7.2.1.3
and see if it resolves your issue.

I am afraid, such issues can be replicated with template files which are causing the problem. I have tried the following code and it is working fine with the latest version.

So, please provide your sample file and the code to replicate this issue.

C#


Workbook workbook = new Workbook();


Worksheet worksheet = workbook.Worksheets[0];


worksheet.Cells[“A1”].PutValue(“Hello World”);

//Testing autofit column

worksheet.AutoFitColumn(0);


workbook.Save(“output.xlsx”);
