We have a situation where the validation messages for the ej-grid control are either hidden, or are partially hidden.
In the attached zip file, the 'completely-hidden.png' file demonstrates where it is completely hidden (you'll have to take my word that it is there somewhere).
partially-hidden.png shows that it is hidden by the column headers.
Although it's not an exact replication of our issue, the following demo shows that if you enter an invalid value for the first row, the validation message is not fully visible:
I've included a screenshot of this (called demo.png) in the attached zip file.
On this occasion the message appears below the affected row, but the fact the message is not entirely visible matches our issue.
I've tried playing around with various z-index values but I've not been able to resolve it.
Could you take a look please?
