DataTable.ImportRow is not adding rows

Question

I\'m trying to make a DataTable and then add a couple rows to it. Here\'s my code:

using System;
using System.Collections.Generic;
using System.Linq;
using          


        

Answer 1

Try this code:

dt.Rows.Add(dr)

Answer 2

You first need to add the row:

 dt.Rows.Add(dr);

Then you must call below method to commit it:

 dt.AcceptChanges();

Answer 3

If the row is detached (as it is when it is first created) ImportRows fails silently (no exception) - to be able to import rows you have to Add it into the table. Afterwards you can import it into other tables.

Its May Help you

DataTable table = new DataTable();
table.Columns.Add("Dosage", typeof(int));
    table.Columns.Add("Drug", typeof(string));
    table.Columns.Add("Patient", typeof(string));
    table.Columns.Add("Date", typeof(DateTime));

    //
    // Here we add five DataRows.
    //
    table.Rows.Add(25, "Indocin", "David", DateTime.Now);
    table.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);
    table.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);
    table.Rows.Add(21, "Combivent", "Janet", DateTime.Now);
    table.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);
