How can I set value from textbox suppose if I add value in textbox 17 then it should be considered as 0-17?

how can I set value from textbox suppose if I add value in textbox 17 then it should be considered as 0-17 in datagridview, and then if I add 35 it should be 17-35 in datagridview and suppose after adding two value I am adding third value 25 then it should be 0-17,17-25 and 25-35.

the no. should be between 0 to 100 only and thats I have already done in textbox event. currently I am adding a value directly from text box to datagrid view.

private void AddButton_Click(object sender, EventArgs e)
        {
            
            
            try
            {
                connection = new OleDbConnection("provider=microsoft.ace.oledb.12.0;data source=F:\\Floro_sense\\Floros.mdb");
                connection.Open();
               // if (FloroValueExists(ValueTextBox.Text)) { MessageBox.Show("The floro Value already exists."); return; }
                if (FloroTypeExists(TypeTextBox.Text)) { MessageBox.Show("The floro type already exists."); return; }
               

                OleDbCommand command = new OleDbCommand("INSERT INTO Sflorotype(Sflorovalues, Sflorotypes) VALUES ('" + ValueTextBox.Text + "','" + TypeTextBox.Text + "');", connection);
                var result = command.ExecuteNonQuery();

                OleDbDataAdapter adapter = new OleDbDataAdapter("select * from Sflorotype", connection);
                DataTable table = new DataTable();
                adapter.Fill(table);

                var data = string.Join(Environment.NewLine,
                table.Rows.OfType<DataRow>().Select(x => string.Join(" ; ", x.ItemArray)));

                BindingSource bind = new BindingSource();
                bind.DataSource = table;
                dataGridViewList.DataSource = bind;
                adapter.Update(table);

               
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            finally
            {
                connection.Close();

            }

        }

private void ValueTextBox_TextChanged(object sender, EventArgs e)
        {
            //Add a reference to Microsoft.VisualBasic.dll

            if (Microsoft.VisualBasic.Information.IsNumeric(this.ValueTextBox.Text))

            {

                int i;

                int.TryParse(this.ValueTextBox.Text, out i);

                if (!(i > -1) || !(i < 101))

                {

                    this.ValueTextBox.Clear();

                }

            }

            else

            {

                this.ValueTextBox.Clear();

            }

        }
