The column of 'tbl' are 1. FIRST NAME 2. LAST NAME 3. DATE OF BIRTH 4. AGE 5. GENDER And that of 'tblSwapedColumns' are 1. GENDER 2. DATE OF BIRTH 3. AGE 4. LAST NAME 5. FIRST NAME

The Problem might be the names of your Columns in SQl it would be fine. Try not to name your Field names with Spaces , when Defining your Column names use something like th First_Name or Firstname Last_Name or LastName please Fix that and try to run your code again

I'm not using any SQL Query to fill datatable. I'm just coying data from one datatable to an other datatable without the use of any Query.

Hi Malik. Just Assign one table to other like DataTable dt=datatable; if one table already contains some records and you don't want to loss that then use the following code.

//copy tbl1 to tbl2
public DataTable MergTables(DataTable tbl1, DataTable tbl2)
{
if (tbl1.Rows.Count > 0)
{
foreach (DataRow row in tbl1.Rows)
{
DataRow newrow = tbl2.NewRow();
newrow["Col1"] = row["Col1"].ToString();
newrow["Col2"] = row["Col2"].ToString();
newrow["Col3"] = row["Col3"].ToString();
tbl2.Rows.Add(newrow);
tbl2.AcceptChanges();

            }
        }
        return tbl2;
    }
