I have a DataGridView in which there are multiple columns, There is a check box Column like this:

I want to sort my datagridview in descending order according to column "weight". But if the checkbox next to weight is checked, that row should go down at the bottom of the list. Finally, I want to have a sorted (in descending order) datagridview according to weight column and I see the unchecked rows first, and then the checked rows. Please help me.

try this

 List<DataGridViewRow> newRowcheck = new List<DataGridViewRow>();

 List<DataGridViewRow> newRowUncheck = new List<DataGridViewRow>();



            foreach (DataGridViewRow row in dataGridView1.Rows)

            {

                if (Convert.ToBoolean(row.Cells[1].Value) == false)

                {

                    newRowUncheck.Add(row);

                }

                else

                {

                    newRowcheck.Add(row);

                }





            }





            dataGridView1.Rows.Clear();





            int RowIndex;



            for (RowIndex = 0; RowIndex < newRowUncheck.Count; RowIndex++)

            {

                dataGridView1.Rows.Add();

                dataGridView1.Rows[RowIndex].Cells[0].Value = newRowUncheck[RowIndex].Cells[0].Value;

                dataGridView1.Rows[RowIndex].Cells[1].Value = newRowUncheck[RowIndex].Cells[1].Value;



            }





            dataGridView1.Sort(dataGridView1.Columns[0], ListSortDirection.Descending);



            DataGridView tempDataGridView = new DataGridView();

            tempDataGridView.Columns.Add("Column1", "Column1 Name in Text");

            tempDataGridView.Columns.Add("nColumn2", "Column2 Name in Text");



            for (int i = 0; i < newRowcheck.Count; i++)

            {

                tempDataGridView.Rows.Add();

                tempDataGridView.Rows[i].Cells[0].Value = newRowcheck[i].Cells[0].Value;

                tempDataGridView.Rows[i].Cells[1].Value = newRowcheck[i].Cells[1].Value;

            }



            tempDataGridView.Sort(tempDataGridView.Columns[0], ListSortDirection.Descending);      



            for (int i = 0; i < tempDataGridView.Rows.Count; i++)

            {

                dataGridView1.Rows.Add();

                dataGridView1.Rows[i + RowIndex - 1].Cells[0].Value = tempDataGridView.Rows[i].Cells[0].Value;

                dataGridView1.Rows[i + RowIndex - 1].Cells[1].Value = tempDataGridView.Rows[i].Cells[1].Value;

            }
