data gridview tasks

What you can do is create a new datarow and add that to a datatable. That then goes to a dataview which you associate to the datagrid. This example is in vb.net but it should be easy enough to translate to c#

Ive added comments in to help you out

'Define a datatable, datarow and dataview
Dim dt As DataTable
Dim dr As DataRow
Dim dw As DataView


'Associate the currnt datasource to the data table
dt = DataGrid1.DataSource

'Create a new row
dr = dt.NewRow()

'Populate the fields in that datatable
dr("ID") = "100"
dr("MyValue") = "Quomon"

'Add this new DataRow to the DataTable
dt.Rows.Add(dr)

'Now add that DataTable to a new instance of a DataView
dw = New DataView(dt)

'And finally add that dataview to the DataGrid datasource
DataGrid1.DataSource = dw

I think this is the c# equivalent

It assumes u have a datagrid control called dataGrid1
and datasource has 2 columns ID and MyValue

   DataTable dt;
   DataRow dr;

   dt = DataGrid1.DataSource;

   dr = dt.NewRow();
   dr("ID") = "100"
   dr("MyValue") = "Quomon"
   dt.Rows.Add(dr)

   DataView dw = new DataView(dt);
   dataGrid1.DataSource = dw;
