how to sort string as number in datagridview in winforms
Solution 1:
You can register on the SortCompare
event, for example:
private void customSortCompare(object sender, DataGridViewSortCompareEventArgs e)
{
int a = int.Parse(e.CellValue1.ToString()), b = int.Parse(e.CellValue2.ToString());
// If the cell value is already an integer, just cast it instead of parsing
e.SortResult = a.CompareTo(b);
e.Handled = true;
}
...
yourGridview.SortCompare += customSortCompare;
...
I didn't check if that works, but you get the idea... ;)
Solution 2:
You can just convert to Int32 when you assign value to column
DataGridView.Cells["example"].Value= Convert.ToInt32(text);
And it will sort correctly
