Sort DataGridView Data Numerically

Question

0.00/5 (No votes)

See more:

I have an unbound DataGridView w/ multiple columns(10). I add data to it programatically when a button is clicked. The first column contains durations in milliseconds(1000 = 1sec). Each time a row of data is added to the dataGridView, I need it to update the sort list of the rows depending on the value of column1(ms).
I'm using DataGridView1.listSortDirection(ascending), but it sorts them as strings instead of integers, when I need them to be sorted from least(top) to greatest(bottom). Someone mentioned setting the column's dataValueType, but I'm a novice at programming, and have no idea how to do this. Any help would be greatly appreciated.

Sorry for the confusion, but I'm the one who posted that original question. I was having some login problems, and was unable to comment, So I created a new account and asked again. The webmaster got it fixed though, and I posted a reply on that post.

DataValueType is correct - check the type of the field that contains millisecond.
If the type is string sorting would be based on strings.
If the type is numeric, the sort would be based on numbers.

OK, I changed the value Type to numeric, but I'm still getting the same results. I changed the DataValueType in the DataGridView Properties, is this the correct method, or do I need to do it in code?
