The Merge() method of the datatable is used to Merge a datatable (second datatable) and stores the result to the first datatable.
For example , assume the following datatables are present EmployeeDataTable1 and EmployeeDataTable2 .
If you want to merge the data from EmployeeDataTable2 to EmployeeDataTable1 , you could do something like below.
protected void Page_Load(object sender, EventArgs e) { EmployeeDataTable1.Merge(EmployeeDataTable2); }
When merging the datatable , verify if both the datatable contain the same columns and other constraints(if defined)
