Hi, Use ImportRow to import rows from another table ** You can use DataTable.Load method to load data from a IDataReader object, which can be created through DataTable.CreateDataReader Also when load data into datatable, you should call BeginLoadData, EndLoadData so as to turn off event notification(improve performance Regards VIJI RAJKUMAR Pls rate my Answer if it was supportive http://vijirajkumar.blogspot.com

Hi, check the below sample code. it might help you or give you an idea to use the import row `//Fill the datatable before using the sample code datatable dtNodeGridLoadFiles = new datatable(); foreach (DataRow drOnGrid in dtOnGrid.Rows) { if ((drOnGrid != null)) { if (drOnGrid .Length > 0) { dtNodeGridLoadFiles.ImportRow(drOnGrid); } } }` Regards JK Thanks & Regards D.Jeya Kumar(JK)

DataTable dtNew = new DataTable(); dtNew.Merge(dtOrginal); if u make any chnages in dtNew table, it will not effect to the dtOrginal. Regards Raaj
