[c#] How to disable sort in DataGridView?

How can I disable sort in DataGridView? I need to disable the header DataGridView sorting.

For extending control functionality like this, I like to use extension methods so that it can be reused easily. Here is a starter extensions file that contains an extension to disable sorting on a datagridview.

To use it, just include it in your project and call like this

myDatagridView.DisableSorting()

In my case, I added this line of code in the DataBindingComplete eventhandler of the DataGridView where I wanted sorting disabled

Imports System.ComponentModel
Imports System.Reflection
Imports System.Runtime.CompilerServices
Imports System.Windows.Forms

Public Module Extensions

<Extension()>
Public Sub DisableSorting(datagrid As DataGridView)
    For index = 0 To datagrid.Columns.Count - 1
        datagrid.Columns(index).SortMode = DataGridViewColumnSortMode.NotSortable
    Next
End Sub


End Module

Use LINQ:

Datagridview1.Columns.Cast<DataGridViewColumn>().ToList().ForEach(f => f.SortMode = DataGridViewColumnSortMode.NotSortable);

foreach (DataGridViewColumn column in dataGridView.Columns)
{
    column.SortMode = DataGridViewColumnSortMode.NotSortable;
}

If you want statically make columns not sortable. You can do this way

1. Open the EditColumns window of the DataGridView control.
2. Select the column you want to make not sortable on the left side pane.
3. In the right side properties pane, select the Sort Mode property and select "Not Sortable" in that.

You can disable it in the ColumnAdded event:

private void dataGridView1_ColumnAdded(object sender, DataGridViewColumnEventArgs e)
{
    dataGridView1.Columns[e.Column.Index].SortMode = DataGridViewColumnSortMode.NotSortable;
}

I was looking for a way to disable my already existing DataGridView and came across several answers. Oddly enough, the first few results on google were some very old topics. This being the earliest one of them, I decide to put my answer here.

private void dgvDetails_ColumnStateChanged(object sender, DataGridViewColumnStateChangedEventArgs e)
{
    e.Column.SortMode = DataGridViewColumnSortMode.NotSortable;
}

The description when you click on ColumStateChanged in the properties window is:

"Occurs when a column changes state, such as gaining or loosing focus"

Granted there are many ways to do this but I thought I'd add this one here. Can't say I found it anywhere else but then again I only read the first 5 topics I found.

It's very simple:

foreach (DataGridViewColumn dgvc in dataGridView1.Columns)
{
    dgvc.SortMode = DataGridViewColumnSortMode.NotSortable;
}

If you can extend the DataGridView you can override the Sort method with am empty one. This disables Sort for the DataGridView entirely.

public override void Sort(DataGridViewColumn dataGridViewColumn, ListSortDirection direction)
{
    //base.Sort(dataGridViewColumn, direction);
}

Note: You cannot even programmatically sort any column.

private void dataGridView1_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
{
      for (int i = 0; i < dataGridView1.Columns.Count; i++)
      {
           dataGridView1.Columns[i].SortMode = DataGridViewColumnSortMode.NotSortable;
      }
}
