See more:

have two datagridview they are; dgOne and dgTwo,
sql data display in dgOne.
and add checkedlistbox to choose column what we need to copy.
when select rows and select column from checkedlistbox.
problem is cels and rows copy correctly but rows and columns are empty dgOne values not display on dgTwo. below is the code that I tried.

What I have tried:

else if (chekAll.Checked == false)
                {

                    try
                    {
                        List<string> list = new List<string>();
                        
                        foreach (var item in checkedListBox1.CheckedItems)
                        {
                            list.Add(item.ToString());
                        }

                        DataTable table = new DataTable();

                        for (int i = 0; i < list.Count; i++)
                        {
                            table.Columns.Add(list[i].ToString(), typeof(string));
                        }

                        foreach (DataGridViewRow row in dgOne.Rows)
                        {
                            bool isSelected = Convert.ToBoolean(row.Cells["Column0"].Value);

                            if (isSelected)
                            {

                                DataRow rowitem = table.NewRow();

                                for (int i = 0; i < list.Count; i++)
                                {
                                    int count;
                                    if ("Serial No" == list[i]) {
                                        count = 1;
                                    }
                                    else if ("Register No" == list[i])
                                    {
                                        count = 2;

Here, have a look at this previously answered query: How can I copy selected column data and row from one datagridview to another in C# using checkedlistbox.[^]

BTW, for learning, do have a look at this: Copy datagridview row into another datagridview[^]
