I have a grid, and a combobox column and datetime column that I added programmatically inside the grid.
The datetime column and combobox column initially look like any other text column. However, once you click on them, a small triangle appears on their right.
In the attached pictures, the first 5 columns text column, 6th datetime and 7th combobox column. But they all look like text columns.
How can I change the initial appearance of these two columns; for example, can I display a calendar icon to the right of the DateTime column and a triangle to the right of the ComboCox column?
