Hi Kind,
Thanks for contacting Syncfusion support.
Regarding your first query of “Does CellTextSize work for GridTemplateColumn at all ”
Initially, we don’t know which view would be loaded inside GridTemplateColumn. So, CellTextSize property is not applicable for GridTemplateColumn.
Regarding your Second query of “If so, will it be propagated to controls inside the DataTemplate ”
As mentioned in the previous query, CellTextSize is not works for GridTemplateColumn.
Regarding your third query of “If not,is there a general way of setting the font size in GridTemplateColumn ”
There is no general way available for setting the font size in GridTemplateColumn. For TimePicker, there is no inbuild FontSize property. However, you can achieve your requirement of setting font size for TimePicker by customizing the TimePickerRenderer.
