I've successfully made the columns in a DataGridView format numbers correctly
using the Format porperty. Now I'm trying to do the same with textboxes, but
the Mask property doesn't work the same way. In fact at run-time, it displays
the number from left-to-right in the mask. (If the mask is 00,000,009.99,
then 100 is displayed as 10,0 , . ) Is there a way to make the textbox
behave the same way as the DataGridView columns?
