Write this code on Button_Click Event

if (this.dataGridView1.SelectedRows.Count > 0)
            {                        dataGridView1.Rows.RemoveAt(this.dataGridView1.SelectedRows[0].Index);
            }

That depends on how you wants to delete your data from datagridview.Here i mentioned some links that describes different delete approaches:

Following is solution Deleting a record via Delete button or by clicking keyboard delete button for selected row

private void Form1_Load(object sender, EventArgs e)
        {
            this.dgview.CellClick += new DataGridViewCellEventHandler(this.dgview_CellClick);
            this.dgview.UserDeletingRow += dgview_UserDeletingRow;
            loadData();
        }

private void loadData()
        {
            try
            {                
                   DataTable dt =new DataTable();
                   DataColumn dc;
                   dc=new DataColumn("ID", typeof(int));
                   dt.Columns.Add(dc);
                   dc=new DataColumn("FirstName", typeof(string));
                   dt.Columns.Add(dc);
                   dc=new DataColumn("LastName", typeof(string));
                   dt.Columns.Add(dc);                  
                 
                   dt.Rows.Add(1,"Ali","khan");
                   dt.Rows.Add(1,"Affan","raja");
                   dt.Rows.Add(1,"Amjad","marwat");
                   dt.Rows.Add(1,"Zohaib","awan");

                    dgview.DataSource = dt;
                
                    foreach (DataGridViewColumn column in dgview.Columns)
                    {
                        column.SortMode = DataGridViewColumnSortMode.NotSortable;
                        column.AutoSizeMode = DataGridViewAutoSizeColumnMode.DisplayedCells;
                    }

                    if (dt.Rows.Count > 0)
                    {
                        DataGridViewButtonColumn btn = new DataGridViewButtonColumn();
                        dgview.Columns.Add(btn);
                        btn.HeaderText = "Delete";
                        btn.Text = "Delete";
                        btn.Name = "btnDelete";
                        btn.UseColumnTextForButtonValue = true;
                    }
               
            }
            catch (Exception ex)
            {
                throw ex;
            }
        }

// this can work when you press delete button in gridview at columIndex=3

private void dgview_CellClick(object sender, DataGridViewCellEventArgs e)
       {
           if (e.ColumnIndex == 3)
           {
               dgview.Rows.RemoveAt(e.RowIndex);
               int ID = Convert.ToInt32(dgview.Rows[e.RowIndex].Cells["ID"].Value.ToString());
               //Send call to you db for updated the ISDelete bit where yourPrimaryID=ID
           }
       }

// This can work when select a row and clicking delete key from keyboard

private void dgview_UserDeletingRow(object sender,DataGridViewRowCancelEventArgs e)
       {
           DialogResult response = MessageBox.Show("Are you sure you want to delete this row?", "Delete row?", MessageBoxButtons.YesNo, MessageBoxIcon.Question, MessageBoxDefaultButton.Button2);
           if ((response == DialogResult.No))
           {
               e.Cancel = true;
           }
           else
           {
               //int ID = e.Row.Cells["yourPrimaryID"].Value.ToString();
               //Send call to you db for updated the ISDelete bit where yourPrimaryID=ID
           }
       }
