Sort Datagrid by Column contents

Question

4.00/5 (1 vote)

I want to order the data in a grid based on a column contents.

I have tryed the instruction (OperationGrid is my grid's name, and "Part Number" the title of the first column)

C#

OperationGrid.Sort(OperationGrid.Columns["Part Number"], ListSortDirection.Ascending);

In that case, I get the error
"Value cannot be null.
Parameter name: dataGridViewColumn"

Any idea of where can the error come from?

and also

C#

OperationGrid.Sort(OperationGrid.Columns[0], ListSortDirection.Ascending);

Now I get the error "DataGridView control must be bound to an IBindingList object to be sorted".

Any idea of where can the error come from?
Maybe I forgot something to define? but the grid works fine without sorting.

I believe that the problem is that I have forgotten something to declare or a type can be wrong. Any idea about that?

Thank you in advance.
David

Your first error "Value cannot be null. Parameter name: dataGridViewColumn" could be a misspelling of the column name ... e.g. is it PartNumber or Part number. I can't reproduce the 2nd error which is why I'm posting this as a comment rather than a solution

Thank you for the suggestion but it is not a misspelling, as I copied the value direct from the configuration file. I also used the array index that refers to this column (like col[0].Title) with the same results.

I would like to avoid sort it programmatically. It is a lot of work and as the sorting method already exists, it must be something that I left to do, but I do not guess what.

Define the IComparable feature and create the comparison feature inside the class:

C#

public class Component : IComparable<component>
{
   private string PartNumber;

...

   public int CompareTo(Component toSort)
   {
      return PartNumber.CompareTo(toSort.PartNumber)
   }

...

}
</component>

Usage:

private void ListSort(list<component> _list2Sort)
{
   _list2Sort.Sort();
}

</component>
