Hi Elster,
Thanks for choosing Syncfusion Products.
Currently, we haven’t support rowheight property in DataTemplate. You can achieve you requirement by setting the RowHeights property in the code behind. For more information please refer the code snippet and sample.
[Code Snippet]
[C#]
void _grid_Loaded(object sender, RoutedEventArgs e)
{
_grid.Model.RowHeights[2] = 90;
}
Please let us know if you need more information.
Thanks,
Karthick
