Try something like this:

            // set up dgv

            dataGridView1.ColumnCount = 3;

            dataGridView1.Columns[0].HeaderText = "Id";

            dataGridView1.Columns[1].HeaderText = "Name"; 

            dataGridView1.Columns[2].HeaderText = "ItemToBuy";

            dataGridView1.AutoSizeRowsMode = DataGridViewAutoSizeRowsMode.AllCellsExceptHeaders;

            dataGridView1.Columns[2].DefaultCellStyle.WrapMode = DataGridViewTriState.True;

           

            string[] data = 

            {

                "1,mike,Toshiba portage",

                "1,mike,Dell latitude",

                "2,nancy,Toshiba portage",

                "2,nancy,Sony vaio",

                "3,rosa,Asus",

                "3,rosa,Hp",

                "4,farid,Sony vaio",

                "4,farid,Hp"

           };

           // analyze data and create rows

           Dictionary<string, int> dict = new Dictionary<string, int>(); 

           int rowNum = 0;

           foreach(string line in data)

           {

               string[] items = line.Split(',');

               

               if (dict.ContainsKey(items[0]))

               {

                   dataGridView1.Rows[dict[items[0]]].Cells[2].Value += "\r\n" + items[2];

               }

               else

               {

                   dict.Add(items[0], rowNum);

                   dataGridView1.Rows.Add(items[0], items[1], items[2]);

                   rowNum++;

               }

           }

Hi Vulpes thank you for replay but i want really separated row

Answer 3

You have to set the column's WrapMode property to true to get it to accept multiple lines of text in the first place.

However, if you try the code, you'll see that the text is not actually wrapping because I'm using "\r\n" to force a new line before the next computer name is added for a particular ID.

try this

 DataTable dt = new DataTable();
            DataRow dr = dt.NewRow();
            dt.Columns.Add("Id", typeof(int));
            dt.Columns.Add("Name", typeof(string));
            dt.Columns.Add("ItemToBuy", typeof(string));
            dr["Id"] = 1 ;
            dr["Name"] = "Mike";
            dr["ItemToBuy"] = "Toshiba portage";
            dt.Rows.Add(dr);
            DataRow dr1 = dt.NewRow();
            dr1["Id"] = 1;
            dr1["Name"] = "Mike";
            dr1["ItemToBuy"] = "Dell Latitude";
            dt.Rows.Add(dr1);
            DataRow dr2 = dt.NewRow();
            dr2["Id"] = 2;
            dr2["Name"] = "nacny";
            dr2["ItemToBuy"] = "Dell Latitude";
            dt.Rows.Add(dr2);
            DataTable dt1 = new DataTable();


            dt1.Columns.Add("Id", typeof(int));
            dt1.Columns.Add("Name", typeof(string));
            dt1.Columns.Add("ItemToBuy", typeof(string));
         
           
            var query = from row in dt.AsEnumerable()
                        group row by row.Field<int>("Id") into grp
                        select new
                        {
                            Id = grp.Key,
                            name=grp.Select(m=>m.Field<String> ("Name")).First(),
                            Joined = string.Join(" ", grp.OrderBy(s => s.Field<int>("Id"))
                                          .Select(s => s.Field<string>("ItemToBuy")))
                        };
            foreach (var grp in query)
            {
                DataRow row = dt1.NewRow();
                row["ID"] = grp.Id;
                row["Name"] = grp.name;
                row["ItemToBuy"] = grp.Joined;
                dt1.Rows.Add(row);
            }
           


Now in your datatable Dt1 you wil have the format as you wanted.. Check the attached solution
