I'm sorry to say you always have the same answer " We are a little unclear about your scenario " what I said is clear "when I added the sfdatagrid to the form I added the columns manually" so when I load the form I see the header although I made the height to 0, I think it's more clear now!
Currently, we have understood your scenario, in that you mentioned the pre-columns for defining the columns using the designer. We have checked the reported issue “HeaderRowHeight does not update properly while defining the columns in designer and set HeaderRowHeight in the code behind” on our end and it is confirmed as a defect. And We have logged a bug. We will include this fix in our NuGet release which is scheduled on January 03, 2023. We will share the feedback link for this issue by tomorrow December 20, 2022.
