Question

I have a datatable which contains 10 rows. I now need to insert 11th row at the position specified by some conditions.

I have tried the InsertAt method but that gives the error of “this row already belongs to another table”.

I cannot use ImportRow method as that simply import the rows into datatable and inserts the row at the end of the existing rows.

What should i do? Kindly help!

Thanks

UPDATED CODE

        int iCount = 0;
        foreach (DataRow dr in dtWithBundle.Rows)
        {
            DataRow drClone = dtOppClone.NewRow();
            drClone.ItemArray = dr.ItemArray;
            dtOpps.Rows.InsertAt(drClone, iIndex + iCount);
            //dtOpps.ImportRow(drClone);
            //dtOpps.Rows.Add(drClone.ItemArray); // Commented on Aug-4 2011 1700HRS
            iCount++;
            dtOpps.AcceptChanges();
        }

Try this. I think the error you are getting is bcz you are not creating NewRow.

    DataTable dt = new DataTable();
    dt.Columns.Add("Name", typeof(string));

    DataRow dr;
    dr = dt.NewRow();
    dr[0] = "A";
    dt.Rows.Add(dr);

    dr = dt.NewRow();
    dr[0] = "C";
    dt.Rows.Add(dr);

    dr = dt.NewRow();
    dr[0] = "B";
    dt.Rows.InsertAt(dr,1);

    foreach (DataRow d in dt.Rows)
    {
        Console.WriteLine(d[0].ToString());

    }

    Console.Read();
