RadzenDataGrin disabled header

Hi,
After load data dynamically into a data grid I call the Reload and StatHasChanged methods to load the data into the tabel. Data is displayed but the header of the table stays disabled or it just seems to me so.
Could you help me, please?

I don't understand much from your post.

I'm sorry if I was misundersandable.
I want to use an inline editable RadzenDataGrid Component and I found that the header of the table is looks like as if it would be in a disabled state. Its colors are greyed and pale in color.

I'm sorry, I found the cause of this style appearance of my table. I was it.
