We are getting the below error when the focus is moved out of the grid. The telerik rad grid which we are using has got around 45 columns. In the row edit mode, it has got text boxes and drop downs binded to it.
The telerik version which we are using is v4.0.30319 and Visual Studio version is 2015.
If the number of grid columns is around 37, we are not getting any issue.
Please advise us on how to fix this
