Hi there,

we have webgrid control on page, and sometimes we get the following error:

Type : System.FormatException, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
Message : The numeric part ('384.71') of '384.71px' cannot be parsed as a numeric part of a Pixel unit.

Error occurs most frequently when refreshing data in grid. The grid control version is 9_0_7200 and the browser is Internet Explorer 11 (Document Mode 11).

Do you have any idea what could be the problem?

Thank you in advance
