Hi Giuseppe,
Thank you for using Syncfusion products.
We have analyzed your query and we were not able to reproduce the issue. We have created a simple sample of your reported query with the
ClearType text mode and the usual grid appearance exists in both the scenario (i.e.) while loading at the first and then loading in the next consecutive form.
Could you please reproduce the issue in that sample, it would be much helpful for us to provide you the exact solution at the earliest.
