I have a datagridview with a check box column as the first column in it.

I want the users to select multiple check boxes and on a button click event, an SQL update query should be executed based on the values from the second column of the datagridview.

Example query : Update table set confirm=0 where empname in ('Mike','Jack')

Mike and Jack are the selections by the user using the check box column.

Please suggest me a solution for this.

Thanks in advance

please describe your problem properly

Update table set confirm=0 where empname in ('Mike','Jack')
Hi All,

I got the solution finally.

for (int i = 0; i < dtgrdUnconfirm.Rows.Count; i++)
                    DataGridViewCheckBoxCell clmSelect = new DataGridViewCheckBoxCell();
                    clmSelect = (DataGridViewCheckBoxCell)dtgrdUnconfirm.Rows[i].Cells[0];                 
                    if (clmSelect.Value != null &&
                           Convert.ToBoolean(clmSelect.Value) == true)
                        data += (dtgrdUnconfirm.Rows[i].Cells[6].Value.ToString())+",";                        
                data = data.TrimEnd(',');                
                if (lstbxUnconfirm.SelectedItem.ToString() == "ID")
                    updatesql = "update tablename set Confirmed=0 where id in (" + data + ")";
