Hi,

Here is the sample code i tried to add rows dynamically on clicking of "Add New Record".

C#:

public static int count = 0;
protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
{
    DataTable ds = new DataTable();
    RadGrid1.DataSource = addBlankLines(ds, count);

}
private DataTable addBlankLines(DataTable ds, int count)
{
    if (count != 0)
    {
        DataRow drBlank = default(DataRow);

        for (int i = 0; i < count; i++)
        {

            drBlank = ds.NewRow();
            ds.Rows.Add(drBlank);


        }
    }
    return ds;
}
protected void RadGrid1_ItemCommand(object sender, Telerik.Web.UI.GridCommandEventArgs e)
{
    if (e.CommandName == RadGrid.InitInsertCommandName)
    {
        e.Canceled = true;
        count = count + 1;
        RadGrid1.Rebind();
    }
}

Thanks,
Shinu.
