[HELP] Sorting Datagridview Column VB.NET

Question

0.00/5 (No votes)

I have this column named 'quantity' and I use these codes to sort that column.

VB

dgFast.Sort(dgFast.Columns(1), System.ComponentModel.ListSortDirection.Descending)
dgSlow.Sort(dgSlow.Columns(1), System.ComponentModel.ListSortDirection.Ascending)

It sorts but about 3 rows from the top and the remaining sort by themselves.

It looks like they're being sorted as strings rather than as numbers. Ensure that the table contains numeric data.

I've tried to convert it to integer with:

dgcol.columns(1).valuetype = getType(Integer)

but still it sorts incorrectly.

You can specify sorting criteria explicitly. Please see this CodeProject question: How to sort a DataGridView Column numerically?[^].
