Gridview column total
===

There is a gridview which includes 6 columns. I bound the data to some columns. For example, 3 and 5 th columns have data.
I want to show There is 2 data in first columns if there is 3 data in separate columns I want to write 3 in the first column.


    Column1   |   Column2   |   Column3    |   Column4   |   Column5    |   Column6

      2       |             |    stack     |             |   overflow   |


How can I do it?
