Sort Column with Type = CheckBox in DataTable?

Hello,

today I recognized that I can sort all 7 columns in my datagridview but not the column with type checkbox. I want to sort all rows with checkbox set to TRUE.

I found the info that I can not sort the DataTable but only the DataGridView?!

column0 is the column with the CheckBox.

How can I sort the first column with checkbox without destroying my whole code?
public void SetColumnsReadProperty()

        {

            for (int i = 2; i < articlesDataGridView.Columns.Count; i++)

                articlesDataGridView.Columns[i].ReadOnly = true;

             

        }
 

public void BindArticleList(AdsExtendedReader reader)

        {

            if (articlesDataGridView.InvokeRequired)

            {                

                articlesDataGridView.Invoke(uPB, new object[] { reader });

            }

            else

            {

                InitDataGridView();

                dataview.Table.Load(reader);

                articlesDataGridView.DataSource = dataview;

                SetColumnsReadProperty();

            }

        }
 

private void InitDataGridView()

        {

            datatable = new DataTable();

            dataview = new DataView(datatable);

            

            var column0 = new DataColumn { ColumnName = "Artikelfilter", ReadOnly = false, DataType = typeof(Boolean) };           

            datatable.Columns.Add(column0);           

            

            var column1 = new DataColumn { ColumnName = "Punkte", ReadOnly = false, DataType = typeof(int) };

            datatable.Columns.Add(column1);           
 

            articlesDataGridView.AllowUserToResizeRows = false;

            datatable.CaseSensitive = false;

            articlesDataGridView.DataSource = dataview;

            

        }

instead of column0 being a plain DataColumn can you use DataGridViewCheckBoxColumn

then you can set the sort property
column0.SortMode == DataGridViewColumnSortMode.Automatic;

I did the sort thingie already but it did not work, so I saw your post and tried the DataGridViewCheckBoxColumn suggestion, see code below.


The first Column gets displayed so far but when I set some checkbox to true and sort the new checkboxcolumn it doesnt get sorted ALTHOUGH I set the sortmode to every column to AUTOMATIC in the foreach. 
What can I do else?

private void InitDataGridView()

        {

            datatable = new DataTable();

            dataview = new DataView(datatable);
 

            var columnFilter = new DataGridViewCheckBoxColumn(false); // { ColumnName = "Artikelfilter", ReadOnly = false, DataType = typeof(Boolean) };

           // datatable.Columns.Add(columnFilter)
 

            articlesDataGridView.Columns.Add(columnFilter);
 

            foreach (DataGridViewColumn col in articlesDataGridView.Columns)

            {

                col.SortMode = DataGridViewColumnSortMode.Automatic;

            }

            

            var columnPunkte = new DataColumn { ColumnName = "Punkte", ReadOnly = false, DataType = typeof(int) };

            datatable.Columns.Add(columnPunkte);           
 

            articlesDataGridView.AllowUserToResizeRows = false;

            datatable.CaseSensitive = false;

            articlesDataGridView.DataSource = dataview;

            

        }

I have an empty DataGridView on my form. In the code below, I create a datasource and assign it to my grid.  The grid is set to auto generate columns.  I manually add the first checkbox column, so I can easily set the properties I want.
public partial class Form1 : Form

{

    protected DataTable datatable = null;

    protected DataView dataview = null;
 

    private void BindArticleList()

    {

        datatable.Rows.Clear();

        datatable.Rows.Add(new object[] { false, 1 });

        datatable.Rows.Add(new object[] { true, 3 });

        datatable.Rows.Add(new object[] { false, 4 });

    }
 

    private void InitDataGridView()

    {

        datatable = new DataTable();

        datatable.Columns.Add(new DataColumn { ColumnName = "Artikelfilter", ReadOnly = false, DataType = typeof(Boolean) });

        datatable.Columns.Add(new DataColumn { ColumnName = "Punkte", ReadOnly = false, DataType = typeof(int) });

        dataview = new DataView(datatable);
 

        DataGridViewCheckBoxColumn dgvCbColumn = new DataGridViewCheckBoxColumn { DataPropertyName = "Artikelfilter", HeaderText = "Artikelfilter", SortMode = DataGridViewColumnSortMode.Automatic };

        articlesDataGridView.Columns.Add(dgvCbColumn);
 

        articlesDataGridView.DataSource = dataview;

    }
 

    private void Form1_Load(object sender, EventArgs e)

    {

        InitDataGridView();

        BindArticleList();

    }
 

    public Form1()

    {

        InitializeComponent();

    }
 

}

that was the code which helped me:

DataGridViewCheckBoxColumn dgvCbColumn = new DataGridViewCheckBoxColumn { DataPropertyName = "Artikelfilter", HeaderText = "Artikelfilter", SortMode = DataGridViewColumnSortMode.Automatic };
        articlesDataGridView.Columns.Add(dgvCbColumn);
