DataGridView Multiple Column Sorting
Jun 9, 2009I'm trying to sort multple colums in the DataGridView which is unbound. I would prefer to sort by using a DataTable/DataView but for some reason another developer in my team experienced other problems relating to sorting so he abandoned using the DataTable to fill the grid :(
Here is the senario: I want the user to be able to choose which columns they want sort on. The way I envisaged was to show a form with a listbox, a grid and 3 buttons (Add to sort, Remove from sort and Apply Sort).
The list box would be populated from the parent form grid column headings.
The grid will show the columns and sort direction.
Button 1 would add the selected item of the list box to the grid.
Button 2 would remove from the grid the selected row.
Button 3 would Apply the Sort in the order of the grid and the columns SortDirection.
Now I looked at How to: Customize Sorting in the Windows Forms DataGridView Control using the IComparer [URL]
how I can use the IComparer to sort on multiple columns that a user has specified or another way to sort on multiple columns using unbound data.

View 5 RepliesSorting A Unbound Datagridview Column
Sep 8, 2011I have an unbound datagridview that I populate with data. When the user clicks on the column head the datagridview is sorted - which is fine for alphabetic fields but I have a column that contains numeric fields and goes from -100 to +100. This is sorted incorrectly by the number (all the 1s first then all the 2s and so on, ignoring the minus sign). How do I get it to sort my column numerically?

Nov 9, 2009I have a datagridview with a column called "Total Price". This is set to a string value type because I need to always show 2 decimals. For example:
4,3
must be in the datagridviewcolumn:
4,30
So I use string.format for this. However, now I have a problem with sorting because the column is a string value type and numbers get sorted like this:
50
4000
40
300
30
20
10000

Decimal Column In Datagridivew Is Not Sorting Numerically?
Mar 16, 2012I have a datagridview which is bounded to a table m_table constructed in my code. A column named price has decimal type.
DGV.DataSource = m_table
DGV.Columns(columnPrice).ValueType = System.Type.GetType("System.Decimal")
All prices are in decimal. But I found that when clicking the column header of DGV, the price column is sorted like a string. For example:
9.0, 13.5, 8->13.5, 8, 9.0
But I want sort numerically, that is 8,9.0,13.5
I wonder why decimal type cannot be sorted numerically. How to achieve this?
